Why do you think reviews are useful? Do you think informal reviews are more valuable than formal reviews?

Solution

Review is process in which the seniors and the team members examine the requirements and the task that has been done so far, reviews depends on the industry you work ,like in software industry there are code reviews , project requirements e.t.c.

Reviews are the most important part in any product development. It reduces the faliure chances and faults in the system, also there is a track of progress in the development lifecycle.

The most obvious value of software reviews is that they can identify issues earlier and more cheaply than they would be identified by testing or by field use (the defect detection process). The cost to find and fix a defect by a well-conducted review may be one or two orders of magnitude less than when the same defect is found by test execution or in the field.

A second, but ultimately more important, value of software reviews is that they can be used to train technical authors in the development of extremely low-defect documents, and also to identify and remove process inadequacies that encourage defects (the defect prevention process).

Formal and informal reviews depends on the agenda, in formal reviews the agenda  for the formal review must be addressed in the Project Plan but not in the informal reviews. Typically fewer people participate in the informal reviews. There isn\'t the structured meeting led by an appointed chairman. Meeting minutes are not prepared & distributed.

Research studies tend to support the conclusion that formal reviews greatly outperform informal reviews in cost-effectiveness. Informal reviews may often be unnecessarily expensive (because of time-wasting through lack of focus), and frequently provide a sense of security which is quite unjustified by the relatively small number of real defects found and repaired.
