A Practical Root Cause Analysis Workflow for Engineering Teams
Root cause analysis gets better when teams separate symptoms, evidence, hypotheses, validation, and memory instead of jumping straight to the first explanation.


Root cause analysis is not a single moment where someone guesses the answer. It is a workflow for turning messy incident data into a validated explanation.
The strongest teams do this consistently. They separate what happened from what might have caused it, attach evidence to every claim, and preserve the final path so the next engineer does not repeat the same investigation.
1. Start With The Symptom
A good investigation starts by naming the user-visible problem: failed login, payment timeout, boot failure, WiFi drop, API latency, or data mismatch. Avoid starting with a suspected cause too early.
Sagy reads the initial report and extracts the affected system, timeframe, users, environment, severity, and known constraints. That gives the team a shared starting point.
2. Gather Evidence Across Tools
Evidence usually lives across several places:
- Slack or Teams conversations
- Jira tickets and linked incidents
- GitHub pull requests, commits, and issues
- logs, traces, dashboards, and runbooks
- docs and prior engineering decisions
This is why root cause analysis belongs naturally inside an AI incident investigation workflow.
3. Form Hypotheses, Then Validate
A hypothesis is useful only when it can be tested. Instead of saying "probably the deploy," the workflow should say which deploy, which changed file, which error pattern, and which source link supports the idea.
Sagy prepares those hypotheses for human review. The engineer still makes the judgment, but starts with a mapped path instead of scattered tabs.
4. Preserve The Final Path
The last step is the one teams skip most often. After the incident is resolved, capture the symptoms, false leads, commands, links, and validated fix.
That turns the incident into engineering memory. The next investigation begins with what the team already learned.
