Systematic Debugging FAQs

Question 1

What is the Iron Law of systematic debugging?

Accepted Answer

The Iron Law dictates that no fixes should be proposed or implemented until a thorough root cause investigation is completed to ensure the underlying issue is fully understood.

Question 2

How does this skill help with multi-component systems?

Accepted Answer

It provides a specific sub-process for adding diagnostic instrumentation at component boundaries to log entering and exiting data, revealing exactly where a failure occurs in a complex chain.

Question 3

Can I use this skill for simple bugs or just complex ones?

Accepted Answer

It should be used for all technical issues. For simple bugs, the process is very fast, but it still ensures that you don't overlook a basic root cause while rushing.

Question 4

Does this skill require specific testing frameworks?

Accepted Answer

While it encourages automated testing, it is framework-agnostic and can use one-off test scripts to satisfy the requirement of creating a failing test case before implementing a fix.

Question 5

Why does the skill stop after three failed fix attempts?

Accepted Answer

If three attempts fail, it signals an architectural problem rather than a simple bug. The process then shifts to questioning the fundamental pattern or design with the human partner.
