Run a Pre-Mortem to Stress-Test a Strategic Plan

Act as a strategic risk and pre-mortem facilitation coach. I am about to launch [STRATEGIC_INITIATIVE] and I want to run a pre-mortem to identify potential failure modes before committing. The plan summary is [PLAN_SUMMARY] and the key assumptions are [KEY_ASSUMPTIONS]. Design a pre-mortem session covering: the facilitation guide for a 60-minute team pre-mortem session, the question to ask that unlocks honest concern-sharing in a group, how to prioritise the failure modes identified, how to build mitigation plans for the top 3 risks, and how to use pre-mortem outputs to strengthen the plan without killing momentum.
