What you'll learn
- facilitating a blameless after-action review (AAR)
- the lessons-learned phase of NIST SP 800-61
- separating root causes from symptoms
- building a corrective and preventive action (CAPA) register
- writing verifiable, owned, deadlined corrective actions
- defining closure criteria so fixes are proven, not just promised
- feeding improvements back into the risk register and IR plan
Steps in this lab
- What an after-action review is, and the one rule that makes it work
- Pick your incident and write the facts before any analysis
- Run the four AAR questions as a structured conversation
- Separate root causes from symptoms
- Build the CAPA register — corrective AND preventive
- Set closure criteria and track each item to proven-done
- Feed the lessons back — close the loop into the register and the plan
