Perform post-incident analysis

Testing reliability is crucial to validate the resilience of your workload. Conducting thorough post-incident analysis allows you to learn from customer-impacting events and enhances your ability to respond effectively. It ensures that you can limit future incidents and improves overall system reliability.

Best Practices

Conduct Thorough Post-Incident Reviews

• Establish a structured process for reviewing incidents that impact customers to ensure all relevant information is captured. This is essential for understanding root causes and improving reliability.
• Involve cross-functional teams in the review process to gain diverse perspectives and insights, which can lead to more comprehensive solutions.
• Document all findings and recommendations in a centralized repository for future reference, enabling continuous learning and improvement across the organization.
• Communicate findings effectively to all stakeholders, tailoring the information to different audiences (e.g., technical teams, management, customer support) to ensure clarity and promote accountability.
• Create action items from the review that are specific, measurable, achievable, relevant, and time-bound (SMART) to facilitate effective implementation of mitigation strategies.

Questions to ask your team

• Have you documented and reviewed all previous incidents involving your workload?
• What processes are in place to identify the root causes of incidents?
• How do you ensure that corrective actions from post-incident analyses are implemented?
• Are lessons learned from incidents shared across teams to improve overall reliability?
• What metrics do you use to assess the effectiveness of your response to incidents?
• How often do you conduct post-incident reviews, and who is involved in the process?
• Is there a systematic approach to prioritizing and addressing identified risks from incidents?
