90-Day OODA Loop Protocol: Compress Your Decision Cycle for Competitive Advantage

How this programme adapts

Once a week, the player runs a short check-in and reads the week you actually logged — not the week the plan assumed. Every check-in lands on one of the adjustments below. These are the engine's own rules, rendered word for word.

Consolidation week
Consistency comes first. This week holds your current habits exactly and focuses on completing one full observe-orient-decide-act-review cycle, with no new complexity added until your log rate is stable.
Focus on one complete cycle
Your log rate is solid but the cycle count is low. This week narrows the focus to a single situation you will carry all the way from observation through after-action review before opening any new loops.
Orientation challenge week
Your logs show low orientation flexibility this week. The priority is the counter-argument exercise: write the strongest case against your current working model on one open problem before making any further decisions in that domain.
Add one more loop
Your cycle rate and orientation flexibility are both strong. This week adds one additional loop target: pick a situation outside your usual domain and run the full cycle through it.
On track
Your numbers are in a normal range. This week keeps your current rhythm and layers in the next scheduled habit or drill.

Pattern insights are gated behind your own record: the first unlocks after 7 logged days, and every insight states the evidence it stands on. Milestone reviews at day 30, day 60, day 90 read your whole record and choose their coaching from it.

The 90-day programme map

Every day of the programme, in full — the same steps the interactive player walks you through. Expand a week to read its days.

Month 1 — Foundation · Days 1–30

Learn the cycle: build observation habits, map your mental models, and complete your first deliberate loops

Week 1Situation AuditDays 1–7

Day 1 · First Observation 10 min

Your decision cycle begins before any deciding happens. Today you install the one habit that anchors everything else in this programme: a short daily log of what surprised you. Surprises mark the gap between your prediction and reality, and that gap is the raw material of sharper observation. The cycle has names from military decision science — those names are labels; what they describe is how any practitioner gets faster and more accurate at reading dynamic situations.

Set up your observation log now: a notes app, paper notebook, or voice memo; consistency of tool matters more than format
Write your first entry: name one thing from yesterday that you noticed you had missed or that landed differently than you expected
Set a recurring morning reminder labeled 'Observation Log' so tomorrow's entry is already scheduled

Day 2 · Peripheral Vision 10 min

Strong observation needs width, not just depth. Today you practise attention to the edges: the quiet signals, the absent faces, the data that stays the same when you expected it to change. Your observation log habit is already running; today adds one exercise to sharpen its scope.

Before your first meeting or key task today, spend 2 minutes listing what you expect to observe
After the event, add one line to your log noting what fell outside your prediction, however minor it seemed

Day 3 · Signal vs Noise 10 min

Not everything you notice is actionable. Today's exercise in the Situation Audit week is separating signals from background: information that could change what you decide from information that merely fills the picture. The skill is recognising which is which before committing to a frame.

In your observation log today, label each entry as S (signal: could change a decision) or N (noise: context only)
Review the last two days' entries and note whether any noise entries turn out to be signals when you look again

Day 4 · Decision Cue Scan 10 min

In the recognition-primed decision model, practitioners act on cues, not full analyses. Today you add a second running habit: a brief cue log after each significant decision. Noting the 2 or 3 things that actually triggered your choice reveals the cue set your pattern recognition is working from.

After each significant decision today, write the 2-3 cues that most influenced your choice in your decision log
For today's first entry, identify which cues came from direct observation and which came from memory or assumption

Day 5 · Observation Audit 15 min

You are four days into your observation log. Today you step back and look across the entries rather than adding a new one. Patterns in what you consistently notice and what you consistently miss are more informative than any single surprising entry.

Re-read your observation log entries from days 1 through 4 in a single sitting
Write two lines: one type of signal you notice reliably, and one type you appear to miss or log late

Day 6 · Information Gaps 10 min

A decision cycle also depends on what you did not observe. Today you map the gaps: the information you would have wanted before a recent decision but did not have. Naming gaps makes them visible and turns absence into a searchable cue type.

Pick one decision from the last week and list the information you wish you had had at the time
Mark each gap as either collectable (you could have found it) or unavailable (genuinely missing at the time)

Day 7 · Week 1 Synthesis 15 min

You have completed the Situation Audit week. Today you consolidate what you have learned about your own observation patterns before moving into orientation next week. Two habits are running: your daily observation log and your decision cue log. These carry forward automatically from here.

Write a one-paragraph summary of your observation patterns this week: what you notice readily, what you miss, and one gap category you want to close
Set a note at the top of your log labeling your most common gap type so it stays visible during week 2

Week 2Mental Models InventoryDays 8–14

Day 8 · Orientation Audit 15 min

Orientation is the lens through which observation gets interpreted. This week you inventory the mental models shaping how you read your domain. Today you add the third core habit: a weekly orientation review, run on the same day each week, where you note one assumption you updated. This inventory is specific to your decision cycle — you are mapping your schemas as inputs to the observe-orient loop, not as general reasoning tools. The exercise looks similar to a general mental models audit but serves a different purpose: here the output is a cue-set, not a framework selection guide.

Each week on this day, write one assumption about your work or project domain that you updated or revised this week
For your first entry, name the mental model you rely on most heavily to interpret your main work domain
Note whether that model has been revised in the last 6 months or has stayed largely unchanged

Day 9 · Map vs Territory 10 min

Your mental model is a map, not the territory. Maps are always incomplete and sometimes outdated. Today you find one specific area where the map you are currently using diverges from what recent observations suggest is true.

Identify one area in your current work where a recent observation did not fit your working model
Write two sentences: what the model predicted, and what you actually observed

Day 10 · Schema Inventory 15 min

You likely use a small number of interpretive schemas repeatedly, often without noticing. Naming them is the first step toward being able to choose between them deliberately rather than defaulting to whichever one loads fastest. The Mental Models Inventory week gives you time to map this.

List the 3 main frameworks or interpretive lenses you use most often to make sense of situations in your work
For each, write one word that captures its dominant assumption about how things work

Day 11 · Orientation Bias Patterns 10 min

Everyone has a preferred orientation style. Some people orient fast and update rarely; others orient slowly and update often. Neither is universally right. Today you characterise your own default pattern so you can work with it deliberately.

Look back at your decision cue log from week 1 and note whether your cues came mostly from fresh observation or from existing assumptions
Write one line describing your orientation default: do you tend to update your frame quickly on new data, or to hold your frame and seek confirming evidence?

Day 12 · Cross-Frame Practice 15 min

Orientation flexibility means being able to load a second frame onto the same situation. Today you practise this deliberately on a real open problem. The goal is not to find the right frame but to notice what each one highlights and what each one hides.

Pick one current open problem and write how it looks through your primary mental model from day 10
Write a second interpretation of the same problem using a different framework, even one that feels less natural
Note one piece of evidence that each frame foregrounds and one it downplays

Day 13 · Assumption Listing 15 min

Every decision rests on a layer of assumptions that often go unexamined. Surfacing them before acting is one of the clearest ways to spot where an orientation might be wrong. Today you take one active decision and write its assumption layer explicitly.

Choose one active decision you are facing and list every assumption embedded in your current approach
Mark each assumption as tested (you have recent evidence for it) or untested (you are taking it on faith)

Day 14 · Week 2 Review 15 min

You have completed the Mental Models Inventory week. You now have a clearer map of the frames you default to and some of the gaps in them. Three habits are running. Next week moves from orientation into the Decide and Act phases.

Re-read your orientation audit entry from day 8 and your assumption list from day 13
Write one sentence naming the assumption you are least confident in heading into week 3

Week 3Decision TempoDays 15–21

Day 15 · Tempo Inventory 15 min

The Decide phase has a tempo problem in both directions: deciding too fast misses relevant signals, and deciding too slow lets the situation change before action lands. Today you add the fourth core habit: a brief pre-decision pause to name what you know and what you do not before committing. This week is experiential: alongside the tempo audit, you run your first complete cycle on a real current situation today so that the rest of the week can debrief it.

Before any significant decision today, pause for 60 seconds to name: what you know for certain, what you are assuming, and what is still unknown
Map three decisions from the last month: mark each as too-fast (acted before you had key data), calibrated, or too-slow (delayed past the useful window)
Run your first complete cycle on a real current situation: spend 5 minutes observing it, 5 minutes orienting on it, 2 minutes deciding, and take one small action before end of day; set a reminder for 48 hours from now to note what changed

Day 16 · Recognition Drill 10 min

Rapid decision-making in familiar domains tends to run through pattern recognition rather than option comparison. Today you look back at a past decision where recognition worked well: you saw the situation, knew what kind it was, and chose an action without deliberate analysis.

Identify one past decision where you acted quickly and the outcome was good; describe in two sentences how you recognised the situation type
Write the 2 or 3 cues that were present and that triggered your recognition

Day 17 · Decision Pace Audit 10 min

Not all decisions deserve the same tempo. This week's Decision Tempo theme is about calibration, not speed. Today you review recent decisions specifically for mismatch: cases where your pace did not fit the situation's demands.

List two decisions from the last two weeks where the pace you chose did not match what the situation required
For each, write one sentence on what information you were waiting for or avoiding that drove the mismatch

Day 18 · Pre-Run Simulation 10 min

Before acting on a decision, mentally simulating the action forward is a practical check used in high-tempo domains. You are not evaluating options; you are checking whether the action you are about to take will survive contact with the situation as you understand it.

Choose one upcoming decision and, before taking action, spend 5 minutes describing how you expect the situation to unfold after you act
Note the point in the simulation where your confidence drops; that is where your observation needs to be most active after you act

Day 19 · Commit and Move 10 min

A decision cycle completes only when you act and then observe the result. Today you practise the discipline of committing to one decision and not revisiting it until you have new data. This is not about certainty; it is about completing the loop so feedback can arrive.

Choose one open decision you have been deferring and commit to a specific course of action before the day ends
Write the earliest date when you will have enough new data to re-evaluate; set a reminder for that date

Day 20 · Decision Map 15 min

Mapping one recent decision as a cycle, phase by phase, makes the structure visible and shows where the loop ran cleanly and where it broke down. This is different from simply recalling a decision; it is a structural diagnosis of how the cycle moved.

Pick one decision from this week and write four bullet points: what you observed, how you oriented, what you decided, and what you did
Mark the weakest phase in your four bullets and write one sentence on what was missing there

Day 21 · Week 3 Review 10 min

Decision Tempo week is complete. You have added the pre-decision pause and started mapping your cycle structure. Four habits are running. Week 4 closes the loop: the after-action review transforms completed cycles into learning events.

Review your decision map from day 20 and your tempo inventory from day 15; note which phase is most consistently strong and which is most consistently weak

Week 4Close the LoopDays 22–30

Day 22 · First After-Action Loop 15 min

The after-action review is the feedback mechanism that turns a completed cycle into a learning event. Today you install the fifth core habit: three questions run at the end of any day that contained a significant decision or action. The questions are what you observed, what frame you used, and what you would change.

At the end of each day that included a significant decision or action, answer three questions: what did I observe, what frame did I apply, what would I change next time
Run your first after-action review right now on the decision you mapped in day 20

Day 23 · Loop Anatomy 15 min

A loop is not just the four phases; it is the full arc from the first observation through the moment the result of your action reaches you. Today you trace one completed loop end-to-end to see how long each phase actually took and where time was spent.

Choose one fully closed decision cycle from the past two weeks and write the approximate duration of each phase: how long you observed before orienting, how long you oriented before deciding, and how long between decision and action
Note which phase consumed the most time and whether that allocation felt appropriate given the situation

Day 24 · Surprise Inventory 10 min

After action comes observation of the result, and results often contain surprises. Cataloguing surprises from past actions is a rich source of orientation updates. Today you identify one result from a recent action that arrived differently than your pre-run simulation predicted.

Look back at one action you took this week and note the most significant way the result differed from what you expected
Write one sentence on which phase of the cycle, observation, orientation, or decision, the gap most likely originated in

Day 25 · Orientation Update 10 min

The feedback from week 3 actions is now available. Today you run a deliberate orientation update: you take the surprise from yesterday and ask what your working model needs to change to accommodate it. This is the feedback loop doing its job.

Based on your surprise inventory from day 24, write one specific revision to your current working model in the domain where the surprise occurred
Add this revision to your weekly orientation review log so it carries forward

Day 26 · One Full Cycle 20 min

Today you run a complete OODA cycle deliberately on a current real situation. The goal is to move through all four phases in a single session: observe a situation, orient on it, make a decision, and take at least a small action before the day ends.

Pick a current open situation, spend 5 minutes observing it, 5 minutes orienting on it, 2 minutes deciding, and take one small action before end of day
Set a reminder for 48 hours from now to run your after-action review on this cycle

Day 27 · Peer Check 15 min

A trusted colleague's observation of a situation you have already cycled through often surfaces cues you missed. Today you share one completed cycle with someone else and ask specifically what they observed that you did not mention.

Describe one completed decision cycle to a colleague or trusted peer and ask what they would have added to the observation phase
Log any new cues they surface in your observation log

Day 28 · Four-Week Review 15 min

Four weeks in, your log contains enough material to look for patterns across cycles rather than within single ones. Today you scan your after-action entries for recurring gaps: the same weak phase appearing across multiple loops.

Re-read your after-action entries from days 22 through 27 and mark which phase, observation, orientation, decision, or action, appears most often as the weak link
Write one sentence naming the recurring gap you will focus on first in Month 2

Day 29 · Month 2 Preparation 10 min

Month 2 sharpens and compresses what you have built. Before it starts, you choose one high-stakes situation as your primary training ground for the next 30 days. Having a consistent subject for your loops accelerates the pattern recognition that the Optimisation phase is designed to build.

Name one ongoing situation, project, or domain that will serve as your primary loop subject for Month 2 and write a two-sentence description of why it is a good training context

Day 30 · Camp I: Foundation Complete 15 min

Thirty days complete. You have built five running habits and run your first deliberate cycles. The Foundation phase is done. Month 2 begins tomorrow with sharper observation and a compressed loop tempo.

Review all five habits and confirm each is running: observation log, decision cue log, weekly orientation review, pre-decision pause, after-action loop
Write one sentence per habit describing how consistently it has run and whether it needs any adjustment going into Month 2

Month 2 — Optimisation · Days 31–60

Compress and sharpen: faster observation, more flexible orientation, calibrated decision tempo

Week 5Sharper ObservationDays 31–37

Day 31 · Pre-Meeting Scan 10 min

Month 2 opens with sharper observation. A 2-minute pre-meeting scan, run before any significant conversation or group decision, gives you an explicit prior that makes surprises easier to catch. Today you add this as the sixth core habit.

Before any meeting or high-stakes conversation, spend 2 minutes writing the key uncertainties you are entering with and the one cue you most want to observe
After your first scan today, compare what you wrote beforehand with what you actually observed

Day 32 · Multi-Source Observation 10 min

Single-source observation is vulnerable to confirmation bias: if the source tends to confirm your current orientation, the observation phase stops doing its job. Today you practise drawing from at least three distinct sources before orienting on a current situation.

Choose one active situation from your Month 2 primary training context and list at least three distinct sources of information available to you
Check each source and note one observation from each that you would not have had from any single source alone

Day 33 · Delayed Interpretation 10 min

Orienting immediately on every incoming cue compresses observation before it is complete. Today you practise holding observations without immediate interpretation: collecting three cues and only then asking what they mean together.

In your next significant situation today, log three observations before allowing yourself to orient; write them as plain descriptions with no interpretive language
After collecting all three, write your orientation in a separate step and note how it differs from what you would have said after cue one

Day 34 · Observation vs Inference 10 min

Observation and inference are different operations that often get conflated in the same sentence. Separating them in your log makes the observation phase more reliable by keeping the raw data distinct from your reading of it. Today you practise that separation on three events.

Pick three entries in your observation log from this week and rewrite each one as two parts: the raw fact observed, and the inference you drew from it
Mark any inference that could have a different observation supporting an alternative reading

Day 35 · Peripheral Signal Review 10 min

Five weeks of observation logs now contains a record of what you notice at the edges of your attention. Peripheral signals, the ones that recur without ever becoming central, are sometimes early indicators of a shift in the situation. Today you scan for any that have appeared more than once.

Scan your observation log for any signal or cue type that has appeared in multiple entries without becoming a primary cue
Write one sentence on whether this recurring peripheral signal is worth moving to your active observation focus

Day 36 · Attention Audit 10 min

Observation quality is partly a function of attention management. Today you identify what most reliably diverts your observation in high-tempo situations, whether it is the loudest voice in the room, the most recent data point, or your own most urgent concern.

Name the two most common attention hijacks in your work context: the things that draw your focus away from the signals you most need to track
Write one practical adjustment you can make to your pre-meeting scan habit to counter each one

Day 37 · Week 5 Review 10 min

Sharper Observation week is complete. Your pre-meeting scan habit is running, and you have practised multi-source observation, delayed interpretation, and observation-inference separation. Six habits are active. Week 6 shifts to orientation flexibility.

Review your pre-meeting scan entries from this week and write one sentence on how close your pre-scan predictions were to what you actually observed

Week 6Flexible OrientationDays 38–44

Day 38 · Frame Stress Test 15 min

Orientation flexibility begins with the ability to interrogate your own most confident frames. Today you take the assumption you hold with the highest confidence in your primary training domain and write its most convincing refutation. The goal is not to abandon the frame but to know its limits.

Identify the assumption in your Month 2 training domain that you hold with the highest confidence
Write a 3-5 sentence argument for why that assumption might be wrong, drawing on real observations from your log

Day 39 · Context Shift 10 min

The same situation can look substantially different depending on the role you occupy when you observe it. Today you reorient one current problem as if you held a different role: a customer, a direct report, or a person in a different function than yours.

Choose one open problem in your primary training domain and describe how it would appear to someone with a completely different role or stake in the outcome
Note one cue or concern that becomes visible from that perspective that your current role tends to background

Day 40 · Novel Framing 15 min

Borrowing a framework from an unrelated domain forces your orientation mechanism to use unfamiliar concepts and often surfaces structure you cannot see from inside your expertise. Today you apply a framework from outside your main domain to one current situation.

Name one framework from a domain you know but that is outside your primary work expertise, for example, ecology, architecture, or navigation
Apply that framework to one current situation: what does it highlight, what does it predict, and what does it leave out?

Day 41 · Update Speed Practice 10 min

Orientation update speed is something you can practise. Today you run a timed exercise: you receive a piece of contradicting information and give yourself a maximum of 10 minutes to articulate how it changes your working frame. The constraint forces a decision rather than indefinite deliberation.

Find one piece of data or feedback from this week that conflicts with something you assumed; set a 10-minute timer
Before the timer ends, write the updated version of the assumption that accommodates the new information

Day 42 · Orientation Under Pressure 15 min

Orientation degrades under time pressure if you have not practised it under those conditions. Today you simulate a tight-deadline orientation: 10 minutes to make sense of a real open problem and name the frame you will use to decide.

Choose a real open problem in your primary training domain; set a 10-minute timer and write your full orientation: what you know, what frame you are using, and what you are most uncertain about
Compare the output to what a more leisurely orientation would have produced and note what was different

Day 43 · Durable Assumptions 10 min

Not every assumption needs updating. Some assumptions are durable because they rest on solid, repeatedly-confirmed observations. Today you identify which assumptions in your weekly orientation log have remained unchanged and ask whether their durability is justified or merely habitual.

Review your weekly orientation review entries from the last 5 weeks and note any assumption that has appeared across multiple entries without revision
For each durable assumption, write one sentence on whether it has stayed unchanged because of consistent confirming evidence or because you have not actively tested it

Day 44 · Frame Synthesis 15 min

The Flexible Orientation week closes today. You have worked with multiple frames on the same situation and run orientation under pressure. Today you ask whether two frames you have been using in parallel can be integrated into a single richer model.

Look at two frames from this week's exercises and write a brief description of where they agree, where they contradict, and whether a synthesis that keeps the best of each is possible
Add any useful synthesis to your orientation review log as your updated working model

Week 7Tempo and AccuracyDays 45–51

Day 45 · Orientation Challenge 15 min

The Tempo and Accuracy week starts with the seventh core habit: a weekly orientation challenge. Once each week you write the strongest argument against your current working model on one active problem and sit with it for at least 24 hours before deciding whether to update your frame.

Once each week, write the strongest counter-argument to your current orientation on one active open problem and wait at least 24 hours before deciding whether it changes your frame
Run your first orientation challenge now on the primary training domain from Month 2

Day 46 · Good-Enough Decision 10 min

The speed-accuracy trade-off has a practical resolution for many situations: identifying when you have enough information to act, given the reversibility of the action and the cost of further delay. Today you practise recognising that threshold on a real current decision.

Choose one open decision and run your pre-decision pause; ask explicitly whether you have enough to act now given how reversible the action is
If the answer is yes, act. If not, write the specific piece of information that would move it to yes and by when you expect to have it

Day 47 · Reversibility Map 10 min

Reversibility is one of the most useful lenses for calibrating decision tempo. Decisions that can be undone quickly afford faster action at lower cost; decisions with high lock-in deserve a longer observation window. Today you classify five recent decisions by reversibility.

List five decisions from the past two weeks and classify each as high reversibility (easy to undo or adjust), medium, or low (hard to reverse once taken)
Compare the pace you used for each to its reversibility rating and note any mismatches

Day 48 · Data Threshold 10 min

Setting a data threshold in advance, before pressure builds, is one way to separate the decision of when to act from the pressure of the moment. Today you set an explicit threshold for one current active decision: what must be known, and how confident you need to be, before you commit.

For one current open decision, write explicitly: what is the minimum set of information you need before acting, and what confidence level is required
Note the earliest date you expect to reach that threshold and set a reminder

Day 49 · Acceleration Drill 35 min

Practising a full cycle at high speed on a low-stakes situation reveals where the cycle has slack and where it has structural dependencies that cannot be compressed. Today you run one complete loop in under 30 minutes on a real but low-consequence situation.

Set a 30-minute timer and run a full observe-orient-decide-act loop on a current but low-stakes situation; aim to complete all four phases within the window
After the timer, note which phase was hardest to compress and why

Day 50 · Accuracy Audit 15 min

Fast cycles have costs. Today you review one decision from this month where speed was a priority and ask honestly what accuracy was traded away to achieve that pace. This is not a critique of the decision but a calibration of the trade-off.

Identify one decision from Month 2 where you acted quickly and write what information you did not have at decision time that later proved relevant
Write one sentence on whether having that information beforehand would have changed your decision, and whether the cost of delay would have been worth it

Day 51 · Week 7 Review 10 min

Tempo and Accuracy week is complete. You have added the orientation challenge habit and practised setting data thresholds, assessing reversibility, and compressing cycles. Seven habits are running. Week 8 moves into compressed loops at higher volume.

Review your reversibility map from day 47 and your data threshold from day 48 and note whether your pace decisions this week were better calibrated than in your day 15 tempo inventory

Week 8Compressed LoopsDays 52–60

Day 52 · Tight Loop Practice 15 min

The Compressed Loops week raises the volume of deliberate practice. The goal this week is three complete cycles on your primary training domain, each with an after-action review. Today you plan those three loops and identify the situations that will serve as practice material.

Identify three distinct situations in your primary training domain that you will use as loop material this week; write one line per situation describing the key decision it contains
Start your first loop today: observe the situation for 5 minutes and write your raw observation notes

Day 53 · Parallel Loops 15 min

In practice, decision cycles rarely run one at a time. Today you carry two separate loops in your log simultaneously and notice whether tracking both affects the quality of observation on either one.

Open a second loop in your log today alongside the one from day 52 and observe both situations before orienting on either
Note in your after-action review whether carrying two loops changed how much attention you gave to each observation phase

Day 54 · Interrupted Cycles 10 min

Real cycles get interrupted. A meeting ends, a priority shifts, new information arrives mid-orientation. Today you deliberately interrupt one of your active loops and practise resuming it cleanly: reading your prior notes and re-entering the cycle without losing your position.

Pause one of your active loops before orienting and leave a note for yourself summarising your observation to date
Resume the loop at least 2 hours later and note whether the pause changed your orientation

Day 55 · Recognition Speed 10 min

Six weeks ago you completed your first recognition drill in week 3. Today you run the same exercise again on a current situation and compare: do you recognise situation types more readily now than you did at the start of Month 2?

Observe a current situation for 3 minutes and write the situation type you recognise and the candidate action it suggests
Compare the time and confidence of this recognition to your day 16 drill entry and note any differences

Day 56 · 60-Second Assessment 10 min

A 60-second rapid situation assessment is a practical tool for high-tempo contexts where a full pre-meeting scan is not possible. Today you practise the compressed version: one minute to name the key fact, the key uncertainty, and the most likely next event.

Set a 60-second timer and assess one current situation: key fact, key uncertainty, most likely next event
After the timer, check your assessment against your fuller observation log and note what the compression missed

Day 57 · Cycle Rhythm 10 min

Every situation has a natural cycle tempo: the rate at which meaningful new information arrives and decisions need to be taken. Today you characterise the rhythm of your primary training domain and compare it to the cycle tempo you have been running.

Write down how frequently meaningful new information typically arrives in your primary training domain, whether hourly, daily, weekly, or at variable intervals
Compare that cadence to how often you have been completing full cycles and note whether your tempo is matched, lagging, or ahead of the situation

Day 58 · Month 2 Loop Count 10 min

Counting deliberate loops completed is a structural measure of practice volume. Today you tally how many full cycles you have completed in Month 2, where a full cycle means you observed, oriented, decided, acted, and ran an after-action review.

Count the full cycles you have completed in Month 2 by reviewing your after-action log entries
Write the total and note whether the volume this month feels adequate given the complexity of your primary training domain

Day 59 · Adaptation Rate 10 min

Adaptation rate is the ratio of orientation updates to observations received. A high adaptation rate means your frame is changing with each new cue; a low rate means you are holding your model stable. Today you estimate your rate across Month 2 and consider whether it has been appropriate.

Count how many times in Month 2 you updated your working model in your weekly orientation review versus how many significant observations you logged
Write one sentence on whether your adaptation rate has been higher, lower, or about right for the pace of change in your domain

Day 60 · Camp II: Optimisation Complete 15 min

Sixty days complete. The Optimisation phase is done. You have sharpened your observation, increased orientation flexibility, calibrated your decision tempo, and run compressed loops at higher volume. Month 3 integrates these across new domains.

Review your week 8 loop count and adaptation rate alongside your week 1 synthesis to see the arc from day 1 to day 60
Write two sentences on what has changed most clearly in how you run a cycle between Month 1 and Month 2

Month 3 — Mastery · Days 61–90

Integrate and transfer: run compound cycles, build a personal pattern library, apply across domains

Week 9Pattern RecognitionDays 61–67

Day 61 · Pattern Catalogue 15 min

A pattern library is a personal catalogue of recurring situation types and the cycle responses you have found reliable for each. Building one converts individual loop experiences into reusable decision scaffolding. Today you start a dedicated section in your log for this catalogue.

Create a new section in your log titled 'Pattern Catalogue' and note the format you will use: situation type, cue set, reliable orientation, and first-order action
Add the first entry: one situation type that has appeared multiple times in your logs, with its typical cue set and the orientation you have found most accurate

Day 62 · Loop Count Habit 10 min

Tracking your cycle volume weekly gives you a concrete signal about whether your practice rate is sustainable. Today you add the eighth and final core habit: a weekly loop count recorded in your log. All eight habits now run in parallel.

Once each week, count and log the number of full OODA cycles you completed, where a full cycle includes an after-action review
Log your count for this week and note whether the number is consistent with your target from week 8

Day 63 · Named Patterns 15 min

Naming a pattern gives it a handle that the recognition system can load faster. Short, specific names, drawn from the cue set that triggers the pattern, are more useful than descriptive labels. Today you give names to three recurring patterns from your loop history.

Identify three situation types that have appeared repeatedly in your decision log and give each a short name that captures its key cue or structure
Add all three to your pattern catalogue with their cue sets and the orientations you have used

Day 64 · Pattern Contrast 15 min

Two situations can look similar on the surface but call for different orientations and different cycle tempos. Today you find two patterns in your catalogue that share surface features but diverge at the point of orientation, and you describe what distinguishes them.

Find two patterns from your catalogue that share at least two cues but require different orientations
Write the distinguishing cue or feature that separates them and note how you learned to tell them apart

Day 65 · Anti-Pattern Log 10 min

Anti-patterns are recurring orientations that reliably produce poor cycles. Naming them carries the same benefit as naming productive patterns: once identified, they load into recognition and can be caught earlier. Today you document one.

Identify one recurring orientation or decision tendency in your logs that has consistently led to weaker outcomes and give it a short name
Add it to your pattern catalogue as an anti-pattern with the cue set that tends to trigger it

Day 66 · Cross-Domain Pattern 15 min

Some patterns transfer cleanly across domains; others break down when the context changes. Today you look for one pattern from your primary training domain that you have also used, successfully or unsuccessfully, in a different domain.

Identify one pattern from your catalogue and note one occasion when you applied it outside your primary training domain
Write whether the transfer worked, and if it did not, which element of the cue set was absent in the new domain

Day 67 · Week 9 Review 10 min

Pattern Recognition week is complete. Your pattern catalogue has at least four entries including an anti-pattern and a cross-domain transfer note. All eight habits are running. Week 10 takes the practice into a domain where you hold no prior patterns.

Count the entries in your pattern catalogue and write one sentence on which entry you expect to be most useful in Month 3

Week 10Multi-Domain PracticeDays 68–74

Day 68 · New Domain Entry 15 min

The Multi-Domain Practice week asks you to run deliberate loops in a domain where you hold no prior patterns. Entering a new domain as a deliberate decision practitioner is different from entering it as a domain learner: you are practising the cycle, not the content.

Choose a domain outside your primary expertise where you will run at least two full cycles this week and write a one-sentence description of why it qualifies as unfamiliar
Run the observation phase on your first situation in the new domain and note the cues that are available to you

Day 69 · Beginner Observation 10 min

In unfamiliar territory, observation widens because no strong frame is yet filtering what comes in. Today you use that openness deliberately: you log more cues than usual without sorting or prioritising them, and you notice what your habitual filters would have screened out.

Spend 10 minutes observing the new domain situation from day 68 and write every cue you notice without filtering for relevance
Compare this list to a typical observation log entry from your primary domain and note what the unfiltered approach captured that your usual practice misses

Day 70 · Frame Import 15 min

One of the core multi-domain skills is knowing which frames from your expertise transfer and which ones introduce error. Today you deliberately import one framework from your primary domain into the new domain and trace how it performs.

Apply your strongest framework from your primary domain to the new domain situation and write your orientation as if it were the right lens
Note where the imported frame fits well and where it produces an orientation that feels forced or incomplete

Day 71 · Cycle Speed Comparison 10 min

Your cycle speed in familiar territory reflects accumulated pattern recognition. In unfamiliar territory, the cycle runs slower because each phase requires more effort. Today you measure this difference and treat the gap as useful diagnostic information rather than a performance problem.

Run one full cycle in the new domain today and estimate the time each phase required
Compare these times to a recent cycle in your primary domain and write one sentence on where the extra time in the new domain is going

Day 72 · Expert vs Novice Orientation 15 min

In expert domains, orientation loads a rich schema almost automatically; in novice domains, it assembles slowly from first principles. The difference is informative: it tells you exactly where your pattern library is doing the work and where the cycle is running on raw processing.

Describe in two sentences how your orientation process in the new domain differs from your orientation in your primary domain
Identify the first point in the new domain where you feel your orientation solidifying and write the cue that anchored it

Day 73 · Transfer Log 15 min

At the end of the multi-domain week, you record what transferred and what did not. This log becomes a reference for future domain entries and also refines your understanding of which parts of your cycle are domain-general versus domain-specific.

Write a short transfer log: which habits, frames, or cue types moved cleanly from your primary domain to the new one
Note one thing that did not transfer and write the domain-specific element that was missing

Day 74 · Week 10 Review 10 min

Multi-Domain Practice week is complete. You have run deliberate cycles in an unfamiliar domain, documented what transfers, and identified the limits of your current pattern library. Week 11 builds compound cycles: loops that nest smaller cycles within a larger arc.

Review your transfer log from day 73 and write one sentence on the domain-general principle your cycle practice seems to rest on

Week 11Compound CyclesDays 75–81

Day 75 · Nested Loops 20 min

Compound cycles contain smaller loops within a larger arc. A project decision, for example, might be a large loop containing dozens of smaller daily cycles. Today you map one situation where a large cycle contains smaller ones and practise managing both levels simultaneously.

Choose one ongoing situation that has a long arc and identify the smaller daily or weekly cycles it contains
Draw or write the nested structure: which smaller cycles feed into the observation phase of the larger one, and at what interval

Day 76 · Team Observation 15 min

Group decision cycles are noisier than individual ones because each member's observation and orientation runs partially in parallel and partially in conflict. Today you observe how a group you work with runs, or fails to run, a collective cycle.

In your next team meeting or collaborative session, observe which phase of the cycle the group spends most time in
Note in your log where the group's collective orientation appears to diverge and how that divergence was, or was not, resolved before any decision was taken

Day 77 · Compression Under Stakes 20 min

Compression drills on low-stakes situations build the habit; applying it under real pressure tests whether the habit holds. Today you run a timed full cycle on a decision that actually matters to you, with a 20-minute maximum from first observation to committed action.

Set a 20-minute timer and run a full cycle on a real decision you have been approaching with more caution than the situation probably warrants
Note what the time constraint forced you to prioritise in each phase and whether the output decision felt adequately grounded

Day 78 · Accuracy Preservation 10 min

High cycle speed creates pressure to shortcut observation and compress orientation. Today you identify which accuracy-preservation practices you are keeping at high speed and which ones you are dropping. Knowing what you are trading away is a prerequisite for calibrating the trade-off consciously.

Review the last three compressed cycles in your log and note which observation or orientation steps you abbreviated or skipped
For each shortcut, write one sentence on whether the cost was acceptable given the stakes and reversibility of the decision

Day 79 · Speed Limit Test 15 min

Every domain has a minimum observation window below which orientation becomes unreliable regardless of how strong your pattern library is. Today you find the practical speed limit of your cycle in your primary domain: the compression point where accuracy starts to fall off in a way that matters.

Run two cycles today in your primary domain: one at your usual pace and one compressed by roughly half; compare the orientation output of each
Write one sentence naming the phase that degrades first when you compress, and what the practical minimum time for that phase appears to be

Day 80 · System Review 15 min

With ten weeks of practice and eight habits running, you can now see which elements of the system are doing the most work. Today you review all eight habits and identify which one has changed your cycles most visibly since Month 1.

List all eight habits and rate each from 1 to 5 on how consistently it is running and how much it has changed your cycle quality
Write one sentence on the habit with the highest combined score and why you believe it has had the clearest effect on your cycle quality

Day 81 · Week 11 Review 10 min

Compound Cycles week is complete. You have run nested loops, observed group cycles, and found your speed limit. One week remains. Week 12 integrates the full system through review, synthesis, and the act of teaching what you have built.

Write two sentences on how your understanding of the speed-accuracy trade-off has shifted since day 47 when you first mapped reversibility

Week 12Full IntegrationDays 82–90

Day 82 · Full System Run 20 min

The Full Integration week starts by running the entire system in a single session. Today you describe one complete cycle you have run recently, tracing it from the first observation through the after-action review, and noting how each of the eight habits played a role.

Choose a significant recent cycle from week 10 or 11 and trace it in writing, noting where each habit touched the cycle
Identify any phase where no habit was active and note whether that absence affected the quality of that phase

Day 83 · Observation Portfolio 15 min

Eighty-three days of observation logs. Today you look across the full portfolio, not for individual entries but for the shape of the collection: how your observation vocabulary has changed, how the gaps have narrowed, and which signal types you now catch that you missed in week 1.

Compare three observations from week 1 with three from the last two weeks and write two sentences on what is different about the quality or specificity of the recent entries
Note one category of signal that you now log regularly that was absent from your week 1 entries

Day 84 · Orientation Flexibility Assessment 15 min

Orientation flexibility was the central theme of week 6. Today you run a self-assessment against the baseline from that week. The question is not whether you are faster but whether you now reach for a second frame more readily when the first one runs into contradicting evidence.

Read your frame stress test from day 38 and your cross-frame practice from day 12 and compare how you handled the exercise then to how you handle it now
Write one sentence characterising how your orientation flexibility has changed and one sentence on what drove that change

Day 85 · Decision Tempo Map 15 min

On day 15 you mapped your decision tempo for the first time. Today you draw the updated version: the calibration you now bring to pace decisions, the reversibility lens you applied in week 7, and the compression skills from week 11.

Re-read your day 15 tempo inventory and write a two-sentence description of how your approach to decision pace has changed since then
Write down the two heuristics you use most reliably now to decide how fast to act on a given decision

Day 86 · Pattern Library Complete 15 min

Your pattern catalogue has been growing since day 61. Today you close it out at its current size and review it for completeness: are the entries clear enough that you could hand them to your future self and still find them useful six months from now?

Review every entry in your pattern catalogue and rewrite any that are too vague to trigger recognition; aim for at least 6 entries with clear cue sets
Mark the 3 entries you expect to use most frequently going forward

Day 87 · Long-Loop Trace 20 min

A long loop is a cycle that ran over weeks or months rather than hours. Today you trace one decision from the last 60 days through its full arc: all the observation cycles that fed into it, the orientation updates along the way, and the after-action review you ran on the outcome.

Choose one significant decision from the last 60 days and reconstruct its full cycle arc using your logs
Write two sentences on where the cycle ran cleanly and where the biggest gap between your observation and the eventual outcome appeared

Day 88 · Teaching Loop 15 min

Teaching something you have practised for 88 days exposes the structure of what you know and surfaces the gaps that solo practice can obscure. Today you explain one of your named patterns to a colleague as if they were about to use it themselves.

Choose one pattern from your catalogue and explain it to a colleague in 5 minutes: the cue set, the typical orientation, the first-order action, and when it breaks down
Note any question the colleague asked that you could not answer cleanly and add it to your pattern entry as an open question

Day 89 · System Handover 15 min

Tomorrow is day 90. Today you write the three-sentence summary that your future self needs to re-enter the system after any break: the three habits that matter most, the most important thing your pattern library contains, and the single rule you have found most reliable for calibrating decision tempo.

Write a system handover note of exactly three sentences: your three most important habits, your most valuable pattern, and your most reliable tempo rule
Save it at the top of your observation log where it will be the first thing you see if you return after a break

Day 90 · Summit: Day 90 Complete 20 min

Ninety days complete. You have run your first deliberate cycles, sharpened your observation and orientation, compressed your tempo, built a pattern library, and transferred your practice to new domains. The programme ends; the system you have built does not.

Review all eight habits and confirm each is running; write one sentence per habit on how you plan to maintain it going forward
Read your day 89 handover note and confirm it accurately describes the system you are handing to yourself
Write a final after-action loop on the full 90-day programme: what you observed, what frame you used, and what you would change if you ran it again

The evidence

The frameworks this programme is built on — each anchored to peer-reviewed research, cited with its DOI and verified against the Crossref registry at build time. Where the evidence has honest limits, the framework says so.

Situation Awareness

Endsley, Mica R. · Human Factors · 1995

The three-level model of situation awareness describes how practitioners perceive elements in their environment, comprehend their meaning, and project their future state. This architecture underlies the Observation phase of any decision cycle: the quality of perception sets the ceiling on every downstream step.

Sensemaking and Orientation

Weick, Karl E., Sutcliffe, Kathleen M., Obstfeld, David · Organization Science · 2005

Sensemaking is the process by which people extract cues from a flux of events and fit them into a working frame that guides further perception and action. It maps onto the Orientation phase: updating the mental model that filters what gets noticed and shapes what gets decided.

DOI: 10.1287/orsc.1050.0133

Maitlis & Christianson, 2014 — Review of sensemaking research covering triggers, processes, and outcomes in organisational contexts doi:10.5465/19416520.2014.873177

Naturalistic Decision Making

Klein, Gary · Human Factors · 2008

In high-tempo, uncertain environments, practitioners tend to recognise situations as belonging to known types and mentally simulate a single satisficing action rather than comparing options analytically. The recognition-primed decision model describes this process and informs how the Decide phase of a cycle is trained through repeated exposure to varied contexts.

DOI: 10.1518/001872008X288385

Deliberate Practice and Feedback Loops

Ericsson, K. Anders, Krampe, Ralf T., Tesch-Römer, Clemens · Psychological Review · 1993

Expert performance is shaped by structured practice with immediate corrective feedback, not raw accumulated experience. Ericsson's research identified external feedback from a teacher or coach — not self-directed review — as the distinguishing feature of deliberate practice over mere accumulated experience. This protocol uses after-action self-review as a structured feedback approximation; peer check (Day 27) extends this toward the external feedback that Ericsson's research identifies as central to deliberate practice.

Speed-Accuracy Trade-off

Bogacz, Rafal, Brown, Eric, Moehlis, Jeff, Holmes, Philip, Cohen, Jonathan D. · Psychological Review · 2006

A formal account of the trade-off between response speed and accuracy in choice tasks: committing earlier reduces accuracy; waiting longer raises it at the cost of tempo. Decision cycle training works at this boundary, building calibrated commitment rather than pursuing either speed or accuracy in isolation.

Safety & fit

This 90-day protocol is a structured, educational programme describing decision-making and cognitive practices informed by published research in cognitive science, organisational behaviour, and expertise studies. It is not medical advice and is not a substitute for professional guidance. Every framework it draws on is referenced to peer-reviewed literature for educational context only.

Questions, answered

How much time does this take?

The OODA Loop Protocol runs 90 days across 12 themed weeks. Each day asks for between 10 and 35 minutes of deliberate practice — the daily tasks are listed in the programme map on this page, so you can read the whole arc before you start.

How does the programme adapt to my week?

A weekly check-in reads the week you actually logged — not the week the plan assumed. Depending on the week you actually had, it lands on one of 5 adjustments: Consolidation week; Focus on one complete cycle; Orientation challenge week; Add one more loop; On track. Milestone reviews at day 30, day 60, day 90 read your whole record so far.

Where is my progress stored?

Entirely in this browser. Your daily log, notes, and check-ins live in local storage on this device — no account, no server, and nothing you type is transmitted. You can export your full log as a CSV file or delete everything, at any time, from the My log tab.

Is this medical advice?

No. This is a structured, educational programme built on peer-reviewed research — it is not medical advice, therapy, or a substitute for professional guidance. The full disclaimer, and every framework the programme draws on with its DOI, is on this page.

What happens if I miss days?

The programme is built to absorb real weeks. The weekly check-in works from whatever you logged: a thin week adjusts the plan rather than failing you, and no adjustment ever deletes your record. The adaptation rules above describe exactly how each kind of week is handled.

Where does the evidence come from?

Every phase of the programme is grounded in 5 evidence frameworks — 9 peer-reviewed references in total, each cited with its DOI in the evidence section on this page and verified against the Crossref registry at build time. Where the evidence has honest limits, the framework says so.
