You have replaced informal code reviews with technical reviews for the most complex and critical components, in an attempt to reduce the high number of defects being found during component and integration test levels. The project manager is concerned about the costs of implementing formal reviews and has asked you to measure whether they actually provide a return on investment.

Which three of the following metrics would be MOST effective in helping you to achieve this?

a. Identification of defect clusters across components

b. Number of lines of code reviewed

c. Number of defects found during reviews d Root cause for each defect detected

e Post-review cost of detection and internal failure per defect

f. Type of review

g. Effort to conduct the review including rework
