Minimax Strategy: Always Have a Backup Plan
How to Prepare for the Worst While Working Toward the Best (Game Theory)
Hack №: 669 — MetalHatsCats × Brali LifeOS
At MetalHatsCats, we investigate and collect practical knowledge to help you. We share it for free, we educate, and we provide tools to apply it. We learn from patterns in daily life, prototype mini‑apps to improve specific areas, and teach what works.
We begin with one sentence that frames our aim: we want to work toward the best realistic outcome while keeping a clear, small, immediately deployable Plan B that prevents catastrophic backsliding. The habit is simple to state and harder to keep because it forces us to hold two images at once: the attractive, long‑term plan and the compact, robust fallback.
Hack #669 is available in the Brali LifeOS app.

Background snapshot
- This approach borrows from early game theory (minimax strategies), emergency planning, and resilience engineering. Its practical cousin appears in naval navigation (contingency anchor points) and in startup roadmaps (pivot-ready milestones).
- Common traps: over‑planning for unlikely extremes, false security from vague "plans", and paralysis by too many contingencies.
- Why it often fails: we either make Plans B that are too heavy to maintain, or we never rehearse them; both outcomes mean the fallback is unusable when needed.
- What changes outcomes: specificity (one‑page actions with times and numbers), rehearsal (a micro‑test), and aligning the fallback with daily tasks so it doesn't feel like a separate project.
We will walk, then act. This is meant to be a long reading session interleaved with choices you can make in the next 30 minutes and actions you can perform today. Our aim is practical: by the end of this piece you'll have a concrete Plan B, a tied Plan A, three check‑ins to track progress, and a tiny rehearsal you can run in under 10 minutes.
Why we care, practically
We have watched projects drift because people optimized for the dream—perfect launches, ideal partners, full funding—and overlooked brittle single points of failure: critical suppliers, a one‑person knowledge silo, or an income line that covers 70% of expenses. Preparing for the worst is not pessimism; it’s a calibration of risk and human bandwidth. We don't need to predict every catastrophe; we need to make our plans degrade gracefully.
What this hack is and is not
- It is a daily habit: spend 3–10 minutes reviewing one small contingency tied to a key goal.
- It is an operational pattern: replace vague backups with actionable, rehearsed tasks weighing minutes, counts, or grams.
- It is not a call to stockpile forever or to craft a hundred pages of contingency diagrams that no one reads.
- If we do it correctly, we convert anxiety into micro‑actions and a measurable readiness metric.
A practice story: the Tuesday pivot Last spring we were managing a six‑week product pilot. Our Plan A banked on one supplier delivering a batch of 500 parts on week four. We assumed the supplier's track record (on‑time 90% in the last year) meant we were safe. On Tuesday morning a single line in an email—“delay probable” —changed the calculus. We could have panicked, or we could execute the Plan B we had sketched the prior month: shift to a 12‑unit parallel assembly, source 50 units from a secondary vendor at +15% cost, and cut an aesthetic feature that cost 8 minutes per unit to assemble.
We assumed X (supplier will deliver)
→ observed Y (delay probable) → changed to Z (deploy backup vendor + simplify assembly). The pivot cost us an extra $750 and reduced margin by 4 percentage points, but it kept the pilot timeline and customer trust intact. The Plan B wasn't ideal; it was survivable. That small rehearsed move prevented a major stall.
Step 1 — Clarify our objective and the acceptable range of outcomes (10–20 minutes)
We start with a single decision: what is the one core achievement we cannot let fail in the next 90 days? Keep it tight. Avoid compound objectives. Examples:
- "Ship version 0.9 to 200 beta users by December 15."
- "Cover 80% of monthly expenses from active income streams by quarter end."
- "Finish 20 therapy sessions and apply two techniques to anxiety before summer."
We prefer three calibrations:
Failure mode definition: the event which, if it occurs, triggers full Plan B.
Write these down in one line. A single sentence forces clarity and forces trade‑offs to surface. If you hesitate, ask: what is the practical minimum that preserves the project’s viability? Quantify it. For shipping software, that might be "100 users with 10% weekly retention." For income, "new income covering $1,200 of rent."
Choice and friction: we notice three common anchors that make this step sticky.
- Optimism bias: we inflate the target by 20–50% and understate resource limits.
- Loss aversion: we make the minimum acceptable too close to the target, making plan B expensive.
- Detail fatigue: we attempt to plan every contingency and stall.
We prefer a compact statement and a 10‑minute limit to avoid these traps. Put the sentence into Brali LifeOS now: one task, one due date, one metric. If you do it in under 10 minutes, you've already started the habit.
Step 2 — Identify the single most likely catastrophic interruption (10 minutes)
List three possible single points of failure that would stop the objective: vendor, funding, personal time, mental health, legal, tech. Then select the one with the highest product of probability × impact. This is not about remote catastrophes; it’s about the most plausible thing in the next 6–12 weeks.
Calculate quickly:
- Assign probability as low/medium/high (we'll map to 10%, 30%, 60% for quick math).
- Assign impact as small/moderate/large (map to $100/$1,000/$10,000 or tasks missed).
- Multiply for a quick risk score: probability × impact.
Examples:
- Vendor delay: probability medium (30%), impact large ($3,000) → score 0.3×3000 = 900
- Personal illness: probability medium (30%), impact moderate ($1,000) → score 300
Pick the highest score; that's the thing to prepare against. This focused selection prevents us from scattering energy across many low‑value contingencies.
A micro‑scene: the morning commute decision We once rated a project's risk and early on assumed the "server outage" was rare; after scoring we discovered the "lead technician's one‑person knowledge" had a higher risk score. The morning we realized this, we walked to his desk and asked for a 20‑minute knowledge transfer. It felt awkward, but it replaced suspense with a 20‑minute action that reduced risk by ~60% (in probabilistic terms). The small social cost was worth the measurable reduction in chance of failure.
Step 3 — Create a one‑page Plan B: actors, actions, times, and costs (20–40 minutes)
Translate the risk into a one‑page plan. We insist on four elements:
- Trigger: the explicit observable that activates Plan B (an email, missed payment, server down for 2 hours).
- Immediate actions (first 0–48 hours): 3–6 items with times and owners.
- Sustaining actions (3–30 days): steps to stabilize.
- Costs and margins: a quick estimate of money, time, and quality impacts.
Use concrete units: minutes, counts, grams, dollars. Avoid vague verbs like "contact partner"—specify "email partner with subject X using template Y; allow 48 hours for reply; if no reply, call and leave voicemail number Z."
We assumed X → observed Y → changed to Z pivot must show up here: "We assumed continuous supply → saw delay → changed to partial substitution + reduced feature list." Put that sentence in the plan so it reminds us why we chose the backup.
A Plan B example (for a small product launch)
- Trigger: supplier fails to confirm shipment by T–10 days.
- Immediate actions (0–48 h):
- Purchase 50 units from backup supplier B at +15% cost (estimate: $1,150), 60 minutes owner: procurement.
- Modify assembly instructions to skip non‑essential aesthetic cap (reduces assembly time by 8 minutes/unit), 90 minutes owner: production lead.
- Update customer communication template: schedule email explaining minor cosmetic change, 30 minutes owner: comms.
- Sustaining actions (3–30 days):
- Rebalance inventory plan to hold 30 units in reserve (3 hours).
- Negotiate price adjustment with original supplier for future runs (2 hours).
- Costs: immediate cash outlay +$1,150, margin lower by 4 percentage points, timeline preserved.
We observe the trade‑offs: higher cost and slightly reduced quality for preserved customer trust and timeline. Quantify the value of the timeline—if each delayed week reduces adoption by 20 users valued at $30 each, the cost of delay equals $600/week, which might exceed the backup cost.
Step 4 — Make Plan B minimal and executable in ≤48 hours A Plan B that requires 10 meetings and 200 emails is not a Plan B; it's a second Plan A. We reframe: "Plan B must be executable by one person, using existing resources, within a 48‑hour window, and with clear metrics for success."
Why 48 hours? Because human systems tend to worsen rapidly if we don't stabilize them. A 48‑hour action window buys time to consider longer maneuvers. If nothing in our plan can be completed solo, find the smallest portion someone can do to stop immediate harm.
Micro‑ritual: the 10‑minute readiness test Pick one element of the Plan B and do a dry run in under 10 minutes. It might be:
- Draft the exact email template with subject line and the two key sentences.
- Call the backup vendor and confirm price and two‑day lead time.
- Remove the non‑essential aesthetic part on a single unit and time the assembly.
We assumed full staff coordination → observed that we were one person short → changed to Z (choose the smallest solo action to stop the drift). After the dry run, note in Brali LifeOS: time taken, friction points, and one micro‑improvement.
Step 5 — Link Plan B to daily habit architecture (3–10 minutes daily)
This is the habit core. Every day, for 3–10 minutes, we run a quick micro‑check:
- Check the trigger signals (emails, inventory thresholds, cash levels).
- Run one micro‑task that keeps Plan B alive (call a secondary vendor, confirm a calendar invite, update a simple tracker).
The daily habit keeps Plan B from being a forgotten document. It can be short: spend 3 minutes scanning two rows of a spreadsheet or sending one clarifying message. The habit's cost should be under 10 minutes to avoid resistance. Over 30 days, these 3–10 minute checks compound; they reduce the probability of catastrophic oversight by an estimated 40–70% depending on context.
A practice micro‑scene: the lunchwalk check We take a 10‑minute lunch walk and, while walking, read the day's dashboard on our phone: cash balance, key email flag, and inventory level. On one walk, we noticed inventory for a critical part at 8 units (threshold 10). We made one call, bought 20 units from a local supplier for $240, and avoided a two‑day production stoppage. The action was under 10 minutes and saved an estimated $800 in downtime.
Step 6 — Quantify the costs and benefits (5–30 minutes)
A Plan B that feels overly costly will languish. We must compare the cost of Plan B to the expected cost of failure, using quick math and simple assumptions.
Method:
- Estimate expected loss from failure (Probability × Impact).
- Estimate Plan B cost (cash + time + quality delta).
- If Plan B cost < expected loss, it's economically rational. If not, rethink either the Plan B design or the probability estimate.
Example numbers:
- Probability of supplier failure in next 6 weeks: 30% (0.3).
- Expected impact (lost revenue + reputational damage): $5,000.
- Expected loss = 0.3 × 5000 = $1,500.
- Plan B immediate cost = $750 + 4 hours of work (valued at $120) = $870.
- Since $870 < $1,500, Plan B is justified.
We prefer this simple expected‑value framing because it prevents us from overspending for low‑probability—low‑impact events.
Sample Day Tally (how to reach readiness using 3–5 items)
We like concrete examples. Here's a Sample Day Tally for a small creative studio that wants to ensure client deliverables while growing new income.
Goal: Keep client deliverables on schedule while launching a new online course in 90 days. Minimum acceptable: Deliver all client work on time; course promotion paused if necessary.
Items to reach readiness today:
- Call backup freelancer and negotiate 8 hours of on‑demand work at $30/hour = 8 × $30 = $240 (15 minutes).
- Move $300 into a contingency float (online transfer) (5 minutes).
- Save a "cut list" that reduces course launch tasks by 30% (remove non‑essential items) — list 6 items, reassign 90 minutes of future work (20 minutes now to draft). Totals today: cash reserved $300, contracted backup 8 hours, 90 minutes of deferred work identified. Time spent now: 40 minutes.
This tally provides a measurable record: contingency cash ($300), backup hours (8), deferred work minutes (90). Over a month, these numbers become our operational readiness metrics.
Trade‑offs and constraints we say aloud We always narrate trade‑offs because choices are moral and material. Choosing a backup vendor at +20% cost preserves timeline but reduces short‑term margin. Keeping cash in reserve reduces immediate investment in growth. Each trade‑off has a quantifiable outcome; we record it. If we can accept a 3–5 percentage‑point hit to margin in exchange for timeline certainty, that becomes a policy.
Step 7 — Communicate the Plan B to the smallest necessary circle (10–30 minutes)
Plan B should not be secret and it should not be broadcast to everyone. Decide who absolutely needs to know and what language to use. Use scripts for clear, quick messages.
We prefer two levels of communication:
- Core team (1–3 people): full Plan B with owner assignments.
- Stakeholders (customers, funders): brief, preapproved message templates that we will use if Plan B is triggered.
Keep messages short and factual. For customers: "A minor supplier delay may affect cosmetic finish. We will ship with the same functionality by X date. Expect email update on Y." For internal team: assign the immediate 48‑hour actions and state who is the escalation owner.
A micro‑scene: the 9:30 a.m. check‑in We draft the two templates and send them to our core team. One person objects to the phrasing; we adjust one clause and test it on a colleague. This small interaction costs 12 minutes but reduces miscommunication and preserves public confidence if Plan B is used.
Step 8 — Rehearse and measure (weekly, with a 3–5 minute daily micro‑check) Rehearsal is the most neglected element. We build frictionless practice: one weekly 10‑minute run, comprised of:
- 3 minutes: check triggers and metrics.
- 5 minutes: perform one Plan B micro‑action (draft message, call backup supplier, remove a non‑essential feature from a sample unit).
- 2 minutes: log results and adjust Plan B if needed.
Each week we record two metrics: a readiness score (0–10)
and the time since last rehearsal. Rehearsal increases the likelihood Plan B is usable from near zero to about 70–90% in our experience. We accept that rehearsal consumes time, but it multiplies Plan B usefulness by an order of magnitude.
Mini‑App Nudge If we were to design a tiny Brali module for this, it would be a "48‑Hour Plan B Dry Run" check‑in that asks: (a) What is the trigger? (b) What two actions can I perform in 10 minutes? (c) What did I learn? Use it three times in sequence to convert Plan B from paper to muscle memory.
Common misconceptions and edge cases
- Misconception: Having many backup plans is always better. Reality: many plans increase cognitive load and reduce rehearsal frequency. Prefer one robust Plan B.
- Misconception: Plan B must be cheap to be valid. Reality: cost is a trade‑off; Plan B should be cheaper than expected loss.
- Edge case: Personal health crises. These can be high impact/low control. For personal resilience, focus Plan B on delegating critical tasks and preserving cash for 2–4 weeks. This changes the elements of Plan B (care contacts, automated bill payments).
- Edge case: Legal or regulatory shocks. If these are plausible, Plan B might be "stop actions" rather than "substitute actions"—legal guidance and documentation become key.
Risks and limits
- Plan B can create moral hazard: if teammates know Plan B exists they may deprioritize prevention. We offset this by making Plan B explicitly costly (we quantify cost) so it remains a last resort.
- Over‑reliance on short windows (48 hours) without longer recovery planning can lead to repeated rescues rather than solving root causes. Pair Plan B with a root cause loop every 30 days.
- Cognitive load: maintaining many Plans B increases decision fatigue. Limit to top 1–3 risks per project.
We assumed that a single person could keep Plan B current → observed that in some teams knowledge and ownership diffused → changed to Z: assign a Plan B steward who owns the rehearsal schedule and the two‑minute daily check. This steward role reduced drift dramatically.
How to do this today — step‑by‑step (30–60 minutes)
We want you to leave with a real Plan B and the habit started. Here is a practical sequence you can complete now, in the Brali LifeOS app or on paper.
- 5 minutes: Write the one‑line objective (Target, Minimum acceptable, Failure mode). Put it into Brali LifeOS as a task with due date 90 days out.
- 10 minutes: Rapidly list three single points of failure and score them (probability × impact). Choose the highest score and note it.
- 20 minutes: Draft a one‑page Plan B using the four elements (Trigger; Immediate 0–48h actions with times and owners; Sustaining 3–30 days actions; Costs and margins). Make each action time‑bounded (minutes/hours) and assign an owner—even if it’s you.
- 5 minutes: Run a 10‑minute dry run on one action (write the exact email subject/body, call the backup, or modify one unit to test the simplified assembly).
- 5 minutes: Log the rehearsal and update the Plan B with one micro‑improvement.
- Optional 10 minutes: Create two message templates: one for internal escalation and one for customer communication.
This sequence is practice‑first. It produces a Plan B that is concrete, executable, and rehearsed.
Narrative vignette: the chain of small decisions We recall a month when supply chain anxieties filled the team Slack. We could have held daily panic sessions. Instead, we made three small decisions one morning:
- Decide to reserve $1,000 as float (5 minutes: transfer).
- Sign a two‑hour backup work contract with a freelancer (15 minutes: call and confirm).
- Remove a non‑critical feature from the immediate release plan (10 minutes: update roadmap).
Those three micro‑decisions cost $1,200 and a rearrangement of priorities. The week after, the main supplier missed a shipment. Because we had taken small, decisive actions, we adjusted with the backup and shipped on schedule. The sum of small choices preserved momentum.
Longer view: policy and review (monthly, quarterly)
Plan B isn't a one‑time exercise. We treat it like a policy: every 30 days, review the top risk list and the Plan B status. Every 90 days, perform a deeper review: re‑estimate probabilities, adjust costs, and decide whether to retire or upgrade the Plan B.
A simple review template:
- Score current readiness (0–10).
- List events in last 30 days that affected risk.
- Rehearse one Plan B micro‑action.
- Adjust readiness metric and assign next 30‑day micro‑task.
This routine makes Plan B part of operational rhythm rather than a one‑off checklist. Over time, the habit reduces the variance of outcomes, which is the practical definition of resilience.
Measuring success: metrics and the psychology of numbers We recommend one primary metric and an optional secondary metric:
- Primary: readiness count (number of Plan B elements validated in last 30 days) or minutes of contingency rehearsals logged per month.
- Secondary (optional): contingency cash reserved ($), backup capacity contracted (hours or units).
Numbers matter because they make readiness visible and reduce magical thinking. We prefer weekly micro‑scores: 0–10 readiness, minutes rehearsed, and a single dollar figure for contingency cash. Over three months, aim for:
- readiness score ≥7,
- rehearsed minutes ≥120 total,
- contingency cash enough to cover 2 weeks of critical costs.
How to scale this across teams
For teams, we add two structural pieces:
- Plan B steward: one person who owns the rehearsal calendar and the Plan B documents.
- Escalation rule: define when Plan B triggers are public to the team (e.g., any trigger that would change timeline by >3 days).
We also keep Plan B simple: one page per project and a shared board for proofs of rehearsal. This approach scales because it limits complexity and clarifies ownership.
One alternative path for busy days (≤5 minutes)
If you have only five minutes, do this:
- Review the single trigger you defined. Is any metric within 10% of the trigger threshold? (Yes/No)
- If yes: perform one micro‑action (draft the subject line of the customer message or text your backup contact: "Can you take 4–8 hours over next 48h if needed?").
- If no: check off the daily Plan B micro‑task in Brali LifeOS and log one readiness minute.
This 5‑minute path maintains momentum without derailing busier priorities.
How ready do I feel on a scale of 0–10? (numeric)
Weekly (3 Qs)
— progress/consistency focused
Metrics (numeric measures)
- Readiness minutes logged this week (minutes).
- Contingency cash reserved (USD) OR backup capacity contracted (hours or units).
We recommend logging these metrics weekly in Brali LifeOS. Over a month, they become a durable record of action rather than wishful thinking.
A small case study in numbers
We worked with a freelance studio that used this hack for three months. Their starting metrics:
- Readiness score: 3/10
- Rehearsed minutes per month: 0
- Contingency cash: $0
After 12 weeks:
- Readiness score: 8/10
- Rehearsed minutes per month: 150 minutes
- Contingency cash: $1,200
- Result: one supply glitch avoided a 3‑day delay; cost = $400 for expedited parts; estimated avoided revenue loss ≈ $1,200.
The studio judged the Plan B cost effective and continued the habit.
Final thoughts: the psychology of "prepare but continue" Preparing for the worst while working toward the best is a balancing act. We must avoid two traps:
- Defensive overcommitment: turning Plan B into the primary focus and losing momentum toward Plan A.
- Optimistic neglect: never rehearsing Plan B because it feels distant.
The habit we propose—daily 3–10 minute checks, weekly 10‑minute dry runs, and clear one‑page plans—keeps Plan B lightweight, rehearsed, and usable. It also builds a culture of small, decisive actions that reduce systemic fragility.
We assumed that people prefer to plan for extremes → observed that most people prefer micro‑actions that reduce immediate anxiety → changed to Z: design Plan B as a sequence of micro‑actions, each 3–30 minutes, prioritized by impact.
Mini‑experiment for the week Try this mini‑experiment over one week:
- Day 1: Draft one‑line objective + Plan B trigger (10 minutes).
- Day 3: Draft exact email template + send to core teammate for review (10 minutes).
- Day 5: Run a 10‑minute dry run and log readiness minutes (10 minutes total). You will have spent 30 minutes and created a usable Plan B. Notice how anxiety shifts into concrete steps.
We finish with a small invitation: treat Plan B as an ongoing conversation, not a one‑time anchor. Update it as conditions change. Use the rehearsal to keep it alive, and measure with numbers that matter.
We will check in with you. If you want, open the Brali LifeOS link now, enter your one‑line objective, and tell us the trigger; we will suggest a 10‑minute dry run tailored to that trigger.
