Systematic Debugging: 4-Phase Root Cause Analysis

Overview

Systematic debugging follows a structured 4-phase approach to identify, isolate, and resolve issues efficiently. This methodology prevents the common debugging trap of random changes and ensures comprehensive problem-solving with reproducible results.

The 4-Phase Debugging Process

Phase 1: REPRODUCE - Isolate the Problem

Establish a reliable way to reproduce the issue consistently.

Objectives:

• Create minimal reproduction case
• Document exact steps to trigger the bug
• Identify environmental factors
• Establish success/failure criteria
