trace-fault

Root-cause analysis uses hypothesis-driven investigation to identify the source of software failures before applying fixes. You reproduce the failure, form hypotheses, test them against collected evidence, and document the root cause to guide the correction.

Hypothesis-driven debugging is an investigation workflow that traces faults by forming and testing hypotheses against evidence. It enforces a prove-first approach, ensuring the root cause of unexpected behavior is verified through evidence-based analysis before any fix is proposed.

Structured fault tracing applies to debugging failures, crashes, or unexpected behavior across development, staging, and production environments. It tracks hypotheses and evidence consistently, regardless of the environment where the fault occurs.

The best way to document evidence during a software investigation is through evidence-based root cause documentation. This approach records tested hypotheses and supporting proof, creating a traceable narrative that justifies the final fix and regression tests.

A prove-first workflow prevents premature fixes by requiring evidence to validate the root cause before changes are made. This structured approach avoids introducing new bugs from untested assumptions and ensures fixes target the actual fault.

After identifying the root cause of a crash, transition to a prove-first workflow for fixes and regression tests. This ensures the proposed correction directly addresses the verified root cause and prevents future regressions of the same fault.
