RootCauseAnalysis

A blameless postmortem builds an evidence-based timeline first, framing failures as system conditions rather than individual mistakes, and identifies actionable contributing factors to prevent recurrence.

Mapping root causes for recurring defects uses Five Whys for causal chains and Fishbone diagrams for category mapping, decomposing issues into systemic, actionable causes rather than stopping at proximate cause.

Fault tree analysis is needed for safety-critical security events, applying Boolean logic to evaluate failure paths and identify the deepest cause where you can implement a change within organizational control.

Yes, Kepner-Tregoe supports pre-launch risk inversion and incident analysis by performing IS and IS-NOT deviation analysis to isolate evidence-based contributing factors and produce concrete corrective actions.

Blameless incident analysis actively resists hindsight and confirmation bias by enforcing a timeline-first execution order, ensuring systemic causes are identified through evidence-based decomposition before assigning corrective actions.
