Root Cause Analysis (RCA) is the process of identifying the underlying cause of an incident or failure rather than just addressing its symptoms. It helps teams understand why an issue occurred and how to prevent it from happening again. Often referred to as incident root cause analysis, it is critical for reliable operations.
Without proper Root Cause Analysis, teams may fix symptoms instead of underlying problems, leading to repeated incidents. RCA enables long-term reliability improvements, reduces recurring outages, and strengthens confidence in systems and processes.
After an incident, teams collect relevant data such as timelines, metrics, logs, and deployment history. This information is analysed to identify the primary trigger and contributing factors. Findings are documented, and corrective actions are implemented to prevent recurrence. Teams also use these tools to automate deployment log analysis, eliminating the manual review process from on-call workflows and enabling AI-powered on-call alert reduction by suppressing noise before engineers are paged.
BuildPiper supports effective RCA by correlating incidents with deployments, environment changes, and observability data. This context helps teams quickly identify whether issues stem from recent releases, configuration changes, or infrastructure behavior.
Incident Response focuses on restoring service quickly, while RCA is performed after stabilisation to understand why the incident occurred and how to prevent it.
Metrics, logs, traces, events, and deployment timelines are all critical for effective RCA, especially in distributed systems.
BuildPiper helps with RCA by linking operational incidents to release and deployment context, enabling faster and more accurate identification of root causes.
