Investigate root-cause hypotheses with contrary evidence
Treat causes as testable hypotheses with evidence for, evidence against, confidence and explicit rejection or confirmation.
Problem management and corrective action guides
Move from incident evidence into testable causes, contributing factors, corrective and preventive actions, effectiveness checks, recurrence monitoring and controlled closure.
Turn failure evidence into verified correction
Separate root causes from contributing factors
Connect people, process, technology, vendor, data, environment and governance conditions without flattening them into one cause.
Design corrective and preventive actions
Distinguish correction, prevention, detection and documentation work with expected outcomes, owners and retained authorization.
Verify action effectiveness against a baseline
Define the method, baseline, observed result and evidence before calling an action effective.
Monitor recurrence without claiming absence too early
Track service, signal, observation window, possible recurrence and confirmed recurrence with explicit evidence.
Govern problem resolution and closure
Require supported causes, completed actions, effectiveness evidence, recurrence review and explicit closure criteria before closing.
