You are a Test Manager on a new project.

As the review leader, one of your responsibilities is to plan the review process and select the review items and the appropriate review type for each item1. This activity should be done in the early planning stages of the project, as it will help to define the scope, objectives, and schedule of the reviews. The review items are the work products that will be reviewed, such as requirements, design, code, test cases, etc. The review type is the level of formality and rigor that will be applied to the review, such as informal review, walkthrough, technical review, or inspection2. The selection of the review items and the review type should be based on factors such as the criticality, complexity, and risk of the work products, the availability and expertise of the reviewers, the time and budget constraints, and the expected benefits and outcomes of the reviews3. Therefore, option A is the correct answer. Option B is incorrect because gathering metrics to determine the success of the review process is an activity that should be done after the review process is completed, not in the early planning stages. Option C is incorrect because calculating the ROI for the review process is an activity that should be done after the review process is completed, not in the early planning stages. Option D is incorrect because setting a minimum number of defects to be identified in each review is not an appropriate activityfor the review leader, as it may create a false sense of quality or pressure on the reviewers. References: 1: ISTQB Advanced Level Test Manager Syllabus, Section 2.2.3 2: ISTQB Advanced Level Test Manager Syllabus, Section 2.2.2 3: Review Types - Testing Traveler, the post about review types
