Decision-Making Process - Avoiding Traps
Executive Readiness Lens
Good leaders are not people who never make mistakes; they are people who design decisions so predictable mistakes are less likely. Most bad managerial decisions come from familiar traps: anchoring, confirmation bias, sunk-cost escalation, overconfidence, framing effects, and groupthink. This chapter gives you an operating method to detect and neutralize these traps before they become expensive commitments.
Canonical Grounding
- Simon: bounded rationality explains why managers satisfice instead of optimize.
- Kahneman: System 1 is fast and intuitive; System 2 is slow and effortful.
- Heath and Heath: WRAP provides a practical decision hygiene process.
- Klein: pre-mortem methods improve risk visibility before commitment.
Working Heuristic
Use the TRAPS-5 decision hygiene stack:
- Trigger clarity. Define the exact decision and why it matters now.
- Range of options. Force at least three viable options, not binary choices.
- Assumption challenge. Identify what must be true for each option to work.
- Pre-mortem and tripwires. Assume failure, map causes, and set stop/pivot triggers.
- Score and commit. Choose with explicit criteria, owner, and review date.
When to use this framework
- Capital allocation and portfolio decisions.
- Hiring and promotion calls with long-term implications.
- Crisis response under time pressure.
Key leadership principle
If a decision has no explicit assumptions and no tripwires, it is opinion, not governance.
Corporate Reality Check
Run this check before approving any high-impact decision.
Common failure patterns:
- Binary framing: "do it or do nothing".
- Data collected only to confirm the preferred view.
- Escalation of commitment because of sunk costs.
Failure signals:
- Teams cannot explain why alternatives were rejected.
- Confidence remains high while evidence quality is low.
- Review meetings revisit the same unresolved assumptions.
What to do instead: require option range, disconfirming evidence, and pre-committed tripwires before final approval.
Case Lens
Many post-mortems show that failed decisions were rarely unpredictable; warning signs were visible but ignored. Teams had data, but lacked a process that made dissent, assumption testing, and stop conditions mandatory.
Lesson: decision quality is designed before commitment, not after outcomes arrive.

1. Case Context
A business unit pursued a turnaround program for an underperforming product line. Leadership had already invested heavily and was reluctant to revisit the thesis.
2. Decision Trigger
Performance continued to miss targets for three consecutive quarters while management proposed additional funding.
3. Timeline (Simplified)
| Phase | What Happened | Decision Relevance |
|---|---|---|
| Initial investment | Growth thesis approved | High optimism and narrow scenario range |
| Early misses | KPIs fell below plan | Warning signs framed as temporary |
| Escalation point | More budget requested | Sunk-cost pressure increased |
| Reset decision | Tripwires enforced | Pivot and value preservation |
4. Options Considered
- Continue funding under the original plan.
- Continue with milestone-gated release of funds.
- Pause and redeploy capital to higher-confidence opportunities.
5. Execution Moves
- Added a formal pre-mortem before approving new spend.
- Required one executive sponsor and one independent challenger.
- Set explicit tripwires for continuation versus pivot.
6. Outcomes and Evidence
Decision cycles became faster, fewer low-probability bets were funded, and post-decision audit quality improved.
7. What to Transfer to Managerial Practice
What to copy:
- Three-option rule for major choices.
- Disconfirming evidence requirement.
- Tripwires tied to dates and owners.
What to avoid:
- Momentum approvals based on past investment.
- Confidence language without probability ranges.
8. What We Know vs What Is Inferred
| Category | Statement Type |
|---|---|
| What we know | Bias-driven traps recur across industries and functions. |
| What is inferred | Teams with formal decision hygiene outperform ad hoc judgement over time. |
9. Discussion Questions
- Which trap appears most often in your leadership forum?
- What is one decision where a pre-mortem would change the current plan?
- Which tripwire should be mandatory for capital-intensive bets?
Monday Morning Playbook
30-minute prep

Role-Based Activation
- People Manager: enforce option range and assumption clarity in team proposals.
- Functional Leader: require disconfirming evidence before approvals.
- BU Leader: institutionalize tripwire governance for major bets.
- Strategy Office: maintain a decision journal and quarterly calibration review.
KPI and Evidence Block
Track both decision process quality and outcome quality.
| Metric Type | Suggested Metric | Review Cadence |
|---|---|---|
| Leading | % major decisions with >=3 options considered | Monthly |
| Leading | % decisions with documented tripwires | Monthly |
| Lagging | % decisions meeting target outcomes | Quarterly |
| Lagging | Capital redeployed from failing bets due to tripwires | Quarterly |
| Risk | % decisions without disconfirming evidence review | Monthly |
