Which of the following defect statistics will provide input to be used for improvement in...

Purpose of the Question:

Identifying metrics to improve the defect reporting process by reducing ambiguities or improving accuracy.

Evaluation of Options:

A. Number of defect reports re-opened:

Incorrect. This reflects issues with defect resolution rather than reporting.

B. Number of defects in a particular area of the code:

Incorrect. This metric pertains to defect clustering, not the reporting process.

C. Number of defect reports rejected by the developers:

Correct. Rejected reports often indicate poor reporting quality (e.g., insufficient details, incorrect categorization), directly highlighting areas for improvement.

D. Number of defects found in a phase later than they were introduced:

Incorrect. This is a measure of defect detection efficiency, not reporting quality.

Syllabus Alignment:

The syllabus stresses the importance of using defect metrics to refine processes, including reporting accuracy (TM-2.3.5).
