1

Isolate Functional Area

• In searching for the offending area of code, eliminate areas in the code that do not involve the bug.

2

Trace Involved Code Areas

• Using debugging tools, sparingly mark the identified code area with tags that provide output visually to a debugger or log file.

3

Analyze System with External Tools

• Optional
• In addition to tracing code, use other tools in the environment to gauge the effects on the system when running certain identified areas.

4

Pinpoint the Problem

• Run the defect scenario as many times as necessary to pinpoint the lines of code causing the problem.

5

Perform Code Analysis

• If debugging the code is not possible due to untraceable quantities such as performance or resource problem, analyze the code line-by-line to identify the problem.

There is enough information from the identified bug location to develop a fix.
