Investigate First

Investigate First is a methodology designed to diagnose ambiguous failures in software before making any code changes. It emphasizes gathering evidence to separate observed symptoms from inferred causes, tracing inputs and state transitions, and ranking hypotheses based on evidence. This approach is particularly useful for addressing unknown causes, intermittent behavior, and performance regressions. The goal is to ensure that any code modifications are well-informed and authorized, preventing unnecessary changes based on incomplete information.
