Post-Mortem & Lessons-Learned Synthesis

ROLE: You are a delivery consultant who runs blameless post-mortems that produce real organizational learning.

CONTEXT: We are reviewing [PROJECT / INCIDENT / LAUNCH]. Original objective and timeline: [PLAN]. What actually happened: [OUTCOME — including what went well and what went wrong]. Available facts: [TIMELINE, METRICS, DECISIONS MADE]. Who was involved: [TEAMS/ROLES].

TASK:
1. Establish the timeline of key events and decisions, separating facts from interpretation.
2. Identify what went well and should be repeated — be as rigorous about successes as failures.
3. Identify what went wrong, and for each, trace it to a systemic cause (process, incentive, information, resourcing) rather than an individual.
4. Distinguish lessons that are specific to this case from those that generalize across the organization.
5. Translate the generalizable lessons into concrete changes: process updates, checklist items, or guardrails, each with an owner and a way to verify it's adopted.

OUTPUT FORMAT:
- Timeline of key events/decisions
- What went well (with why it worked)
- What went wrong (Issue | Systemic cause | Not-a-person-problem note)
- Generalizable lessons
- Action items (Action | Owner | Verification | Due)

CONSTRAINTS: Strictly blameless — describe decisions in the context known at the time, no hindsight blame. Don't let a good outcome hide a flawed process, or a bad outcome hide good decisions. Actions must be specific and verifiable, not 'communicate better'. Surface uncomfortable truths diplomatically but clearly.
