Root Cause Analysis That Sticks
01
Resist racing through the questions. Tie each why to observable evidence, not opinions, and stop when you hit a process or assumption that can be measurably changed. Try it on your next incident and report your learnings below.
02
Sketch a quick causal graph showing signals, triggers, and contributing conditions. Visualizing relationships helps avoid scapegoating while revealing leverage points. Grab a whiteboard, snap a photo of your graph, and share it with the community.
03
Think in three layers: stop the bleeding, fix the defect, and harden the system so it never recurs. Keep a short checklist near your desk and comment with additions we should adopt across teams.
Craft a Disprovable Hypothesis
Write a clear statement that could be proven wrong, including expected signals. If it cannot be falsified, it cannot lead you out of confusion. Post your latest hypothesis format and ask readers to pressure-test it.
Design Minimal, Reproducible Experiments
Reduce the moving parts until you can reliably trigger the bug. Capture exact steps, input data, and environment details. A minimal repro is a kindness to your future self—share your best template for others to reuse.
Instrument, Measure, Iterate
Add lightweight probes, logs, or counters focused on your hypothesis. Compare expected versus actual values, then iterate quickly. If a probe teaches nothing, remove it. Comment with a tale where one metric revealed everything.
Decomposition: Slicing Problems Into Solvable Pieces
Before changing code, specify a property that must remain true across all steps, like contract shapes or latency ceilings. Invariants anchor progress. Share one invariant you use daily and invite critique on its precision.
Observability as a Strategy, Not a Tool
Structure logs around user intent, request identity, and outcome. Include timings and correlation keys. Avoid noisy trivia. Paste a sample log line that answered a question instantly, and ask others how they’d refine it.
Distributed tracing reveals where time and errors accumulate. Use spans to reflect meaningful work, not implementation detail. Share a trace screenshot where a single hot span redirected your entire investigation within minutes.
Choose a handful of service-level and error-rate metrics that reflect user pain. Add alert thresholds that encourage investigation, not flapping. Comment with your lean metrics stack and why each metric truly earns its place.
Run Blameless War Rooms
Assign clear roles—commander, scribe, comms—and keep chatter out of the main channel. Decisions are logged, experiments queued, emotions acknowledged. Post a short template your team uses to kick off war rooms effectively.
Ask Powerful, Neutral Questions
Replace accusations with curiosity: What changed? What evidence supports that? What would disprove it? Neutral questions unlock better data and calmer minds. Share a phrasing that consistently turns tension into progress.
Use Decision Records
Capture context, options, trade-offs, and the chosen path. Lightweight records prevent circular debates and guide future audits. Drop a link to your favorite ADR format and invite feedback on making it even faster.
Watch for confirmation bias, sunk cost, and anchoring. Say them out loud in reviews to neutralize their power. Share a moment you escaped a mental trap, and encourage others to do the same.
List hard limits—time, budget, compliance—and soft preferences. Constraints focus creativity rather than kill it. Post your constraint sheet for an upcoming sprint and ask the community to challenge anything ambiguous.
Define what “good enough” means before you begin. Optimize only where it matters to users. Celebrate stopping early when the goal is met. Comment with a story where restraint saved the project’s momentum.
