Performing One Corrective Task at a Time
Always perform one corrective task at a time. Then, repeat the test that you
performed to identify the problem in order to validate the correction. Verify that
the task solved the problem before performing the next corrective task.
This way, you know which task solved the problem. If you perform multiple
corrective tasks without verifying the success of each one, you may unknowingly
make one of the following mistakes:
• Complicate the original problem
• Solve the problem but cause another
• Solve the problem without knowing how you solved it
