How do you approach post-mortem analyses in your organization?
-
Five "Why"s! And five may be too few. "Thorough" is in the eye of the reader. Only those who helped resolve the incident can judge whether the post-mortem is thorough.
-
Effective post-mortems turn downtime into growth by prioritizing learning over blame. Foster psychological safety to address process gaps, not individuals. Merge logs/metrics with team insights to identify root causes (e.g., unpatched firmware from manual workflows). Use the "5 Whys" to uncover flaws, then define fixes: immediate mitigations (manual checks) and sustainable solutions (automation). Share findings transparently, emphasizing business impact (e.g., downtime) and assigning owners. Recognize proactive efforts to reinforce vigilance. This approach reduces repeat incidents, builds trust, and shifts teams from reactive firefighting to prevention. How does your organization strengthen resilience through post-mortems?

After resolving a major network downtime incident, I ensure a thorough post-mortem analysis by following these steps: First, I meticulously document everything—the timeline, the impact, the mitigation steps I took, and the identified root cause, possibly using the 5 Whys technique. Next, I assemble a team representing all affected areas to gain diverse perspectives and ensure comprehensive understanding. We focus on the root cause, not just the symptoms, and brainstorm corrective actions to prevent recurrence. Finally, I prioritize continuous improvement by documenting lessons learned, adjusting processes, and sharing the post-mortem findings widely to promote organizational learning.

After addressing a significant network outage problem, begin by compiling all pertinent information, such as logs, alarms, and team interactions, in order to reconstruct the chronology of events and guarantee a comprehensive post-mortem study. Organize a structured conversation on the impact, root cause, and resolution process with important stakeholders, such as engineers, IT support, and management. Encourage candid criticism and spot procedural and technical flaws by taking a blameless stance. Put remedial measures into place, such as updated response procedures, better monitoring, or upgraded infrastructure. Lastly, to boost future incident response efforts and reinforce learning, share findings with the larger team.

Crisis averted! The network is back, but before we move on, let’s do a post-mortem to prevent a repeat disaster. Step 1: Rewind the Tape – When did the alarms go off? How long were we in panic mode? What finally fixed it? Step 2: What Broke? – Hardware failure? Bad update? Human error? Step 3: Who Felt the Pain? – Users? Services? Any financial loss? Step 4: Could We Have Caught It Sooner? – Were alerts useful? Was our response smooth? Step 5: Lock It Down – Fix weak spots, improve monitoring, and automate. Step 6: Document & Share – Lessons learned, no tech jargon. Step 7: Follow Up – Assign tasks, check progress, and celebrate with pizza!

Case study is the best approach to do a post -mortem analysis just right every detail down about what happened and what actions were taken step by step untill the full resolution this will help you to get insight of vulnerabilities in the deployed network and how to overcome them in future.

Conducting a thorough post-mortem analysis after a major network downtime is crucial for preventing future incidents. First, gather all relevant data, including logs, metrics, and system reports, to get a clear picture of what happened. Next, involve key stakeholders—engineers, administrators, and support teams—who were directly involved, ensuring a comprehensive understanding of the incident. Then, use root cause analysis techniques like the “5 Whys” or fishbone diagrams to identify the underlying issues. Finally, document findings, implement corrective actions, and update response strategies to enhance system resilience. A structured approach ensures continuous improvement and minimizes future disruptions.

A couple of key points that I've learned... 1) take your ego out of the equation. Consider your own actions in both a positive and negative light. Look at how you could have done things better - even if you consider your actions to have been "perfect". 2) Encourage both positive and "less than positive" honest feedback. Ask pointed questions about how you and your team handled things. 3) Create a plan that involves everything you learn and has real, actionable, improvements... Even if they seem small. And share this openly. Call out those whose contributions made an impact Demonstrate that you take feedback seriously and you'll find most people are more patient should things go pear shaped again.

Resolving a major network downtime is just the first step. To ensure a thorough post-mortem analysis, gather all stakeholders to review timelines, root causes, and response effectiveness. Document lessons learned, identify gaps in monitoring or processes, and update incident response plans. Implement preventive measures to avoid recurrence. Transparency and continuous improvement are key to building resilience.

To ensure a thorough post-mortem analysis after resolving a major network downtime incident, follow these steps: 1. Document the Incident Timeline Record when the issue was first detected, reported, and resolved. Note all actions taken and their timestamps. 2. Identify Root Cause Conduct a root cause analysis (RCA) using methods like the 5 Whys or Fishbone Diagram. Check logs, alerts, and configurations to pinpoint the exact failure point. 3. Gather Stakeholder Input 4. Analyze Impact 5. Evaluate Response Effectiveness 6. Develop Preventive Measures Implem 7. Create a Detailed Post-Mortem Report 8. Conduct a Review Meeting
