checklist

description

Activate when: user says 'let's make sure we don't skip anything', 'we need a pre-flight', 'build me a checklist for X', 'we keep missing steps in our deployment / close / launch', 'Gawande / Pronovost / checklist manifesto'. Do NOT activate when: the task is simple and one-off with no recurrence; the user is asking for a to-do list or project plan (not a must-not-skip operational gate). More: deciqai.com/s/checklist

Checklist

Overview

A checklist is a short written list of must-not-skip steps for a complex repeated operation. It externalizes working memory — which fails under load, ego, time pressure, and fatigue — so attention stays on the situation rather than step recall. Boeing 1935 → Pronovost ICU 2001 → WHO Surgical 2008: each produced 36-47% reductions in major adverse events at near-zero cost.

Composes with metacognition, confirmation-bias, cognitive-load-theory, premortem, inversion.

When to Use

• High-stakes repeated operations (deployments, launches, M&A close, hiring decisions, financial close)
• Multiple steps where skipping one costs far more than running the checklist
• Multi-person operations where coordination must be consistent
• New team members joining a critical workflow

Not when: operation is simple/one-off; no recurring pattern exists; checklist culture creates false confidence (mechanical checking without thought).

Coaching Novices (Adaptive Front Door)

• Engine mode: user has a specific operation → run The Process directly.
• Coach mode: user is new to the framework → guide step by step.

In Coach mode, respond one step at a time. Each [WAIT] is a hard stop — output only that step's question, then stop.

1. One-line: for any complex repeated operation, a 6-10 item checklist outperforms expert memory under load — it externalizes the steps that fail systematically.
2. Check fit: repeated + high-stakes + consequential errors = checklist candidate. Simple or one-off = skip.
3. Elicit their real case: what operation, where does it fail, what near-misses have occurred?

[WAIT — do not advance until user responds]

4. Run The Process one step at a time with their input: what items must never be skipped? DO-CONFIRM or READ-DO? who runs it and when?

[WAIT — do not advance until user responds]

5. Close: present drafted checklist + format + workflow integration, name the key reliability insight they uncovered.

[WAIT — do not advance until user responds]

The Process

Step 1 — Identify the operation: operation name, frequency, stakes of errors, current failure modes, near-miss history.

Step 2 — List 15-25 candidate items: steps that have been skipped, steps that prevent major errors, coordination steps, bias-catching steps, reversibility checkpoints.

Step 3 — Cut to 6-10: keep only items that are critical, easily missed by skilled operators, and verifiable (yes/no signal). Longer lists get truncated in use.

Step 4 — Choose format: READ-DO (read → act → next item; use for novices, novel procedures, multi-person coordination) vs DO-CONFIRM (pause → confirm all done; use for skilled experts where flow matters).

Step 5 — Embed in workflow: define trigger, owner, consequence of skipping, and cultural reinforcement (leadership models it, peers enforce it).

Step 6 — Iterate: after each near-miss, check if an item would have caught it and add it. Quarterly review: remove stale items, add new failure modes.

Pack: Domain Patterns

Domain	Gate	Checklist focus
Aviation	Pre-flight	Systems, fuel, weather, navigation, crew brief
Surgery / ICU	Pre-incision / central-line	Patient identity, site, antibiotics, hand hygiene, drapes
Software	Pre-deploy	Tests pass, monitoring, rollback ready, comms sent
Investment	Pre-decision	Bias check, valuation, management, structural risks
M&A / Hiring	Pre-close / pre-offer	Due diligence complete, financing committed, rubric coverage

Applying It Well

• 6-10 items is the empirical optimum; cut ruthlessly — longer lists get skipped.
• Match format (DO-CONFIRM vs READ-DO) to the natural rhythm of the work.
• Cultural commitment is load-bearing: consistent use and genuine attention, not mechanical checking.
• Iterate after every near-miss; the list must evolve with real failure patterns.

Common Rationalizations

[D] = designed upfront | [O] = observed in real use. [O] entries are more valuable.

Fake move	Reality
[D] "I know what I'm doing; I don't need a checklist"	Expert intuition fails under load. B-17's pilot was one of the most experienced of his era.
[D] "Checklists slow us down"	Slightly — but prevent rework and catastrophes. Net benefit overwhelmingly positive.
[D] "Checklists are for amateurs"	Lufthansa pilots, neurosurgeons, and top investors all use them.
[D] "We have one but no one uses it"	Value comes from consistent use. Culture and workflow integration are part of the discipline.
[D] "More items = better"	False. >10 items get truncated. Aim for the critical few.
[D] "We tried one and it didn't help"	Likely wrong design (too long, wrong format, misaligned with workflow). Iterate.
→ Add [O] entries here after each real use — paste the actual failure pattern	What went wrong and why

Red Flags

• Complex repeated high-stakes operation has no checklist; or checklist exists but seniors skip it
• 20+ items and users are truncating it; or near-misses are not updating it
• Items run mechanically without genuine attention; no one owns maintenance

Verification

• Operation identified, failure modes documented, near-miss history noted
• 6-10 items, each critical, easily missed, and verifiable (yes/no signal)
• Format (DO-CONFIRM or READ-DO) matches operation pace and expertise level
• Embedded with clear trigger, owner, consequence of skipping, cultural reinforcement
• Near-miss tracking and quarterly review scheduled
