Root Cause Analysis Step 1

Define/scope the incident

Root Cause Analysis Step 2

Determine the causal relationships that led to the incident

Root Cause Analysis Step 3

Identify an effective solution

Root Cause Analysis Step 4

Implement and track the solutions

Lessons Learned Process

Document experiences during incidents in a formalized way

After-Action Report

Collects formalized info about what occurred
