Standard : Blameless incident reviews focus on learning, not finger-pointing
Purpose and Strategic Importance
This standard ensures that incident reviews are conducted in a blameless manner, prioritising understanding, learning, and systemic improvement over assigning fault to individuals. Focusing on learning fosters psychological safety, encourages open communication, and leads to more effective prevention of future incidents.
It supports the policy “Create a Culture of Respect and Trust” by embedding respect and accountability without fear. Without this standard, fear of blame can suppress transparency, hinder problem resolution, and perpetuate recurring issues.
Strategic Impact
- Promotes honest and transparent incident analysis
- Increases psychological safety and trust within teams
- Drives meaningful, systemic improvements to reduce incident recurrence
- Enhances collaboration and shared responsibility for reliability
- Supports a culture of continuous learning and resilience
Risks of Not Having This Standard
- Incident reviews devolve into blame games, damaging morale
- Underreporting or hiding of issues due to fear of reprisal
- Repeated incidents due to unaddressed systemic causes
- Reduced team cohesion and communication breakdowns
- Slower incident resolution and recovery times
