Inspections are an important part of maintaining quality but

Inspections are an important part of maintaining quality, but if they are not managed properly, they can eat up valuable time. The number of people attending an inspection can have a direct impact on the effectiveness of the review. List the disadvantages of having either too few or too many people attend an inspection. What types of reviews are there? What types of people would you invite to each review

Solution

Too few: not enough people to cover the material, meaning that defects can go undetected. Also, insufficient expertise regarding specialized parts.

Too many: there may be too many different opinions as to what is a defect, leading to confusion. Too many attendees can lead to more comments than are needed, causing the inspection to take longer than scheduled.

--------------------------

Those peers who abide by the following criterias must be selected -

(1) The efforts of each reviewer should be focused on those aspects of the design that suit his experience and expertise. (2) The characteristics of the reviewers needed should be explicitly specified before reviewers are selected. (3) Reviewers should be asked to make positive assertions about the design rather than simply allowed to point out defects. (4) The designers pose questions to the reviewers, rather than vice versa. These questions are posed on a set of questionnaires that requires careful study of some aspect of the design. (5) Interaction between designers and reviewers occurs in small meetings involving 2-4 people rather than meetings of large groups.
