Debug It!

Put It in Action

• Make sure to do the following:

  • Work out why the software is behaving unexpectedly.

  • Fix the problem.

  • Avoid breaking anything else.

  • Maintain or improve overall quality.

  • Ensure that the same problem does not occur elsewhere and cannot occur again.

• Leverage your software’s ability to show you what’s happening.

• Work on only one problem at a time.

• Make sure that you know exactly what you’re looking for:

  • What is happening?

  • What should be happening?

• Check simple things first.
