Software Reviews

Software reviews are the filter for the software engineering process. They re applied at various different points and serve to uncover errors that can be removed and help to purify the software engineering activities.
In this context it is useful to look at the “V-model” of software development. This model emphasizes that SQA is a function performed at all stages of software development life cycle. At the initial stages (requirement, architecture, design, code), it is achieved through activities known as Formal Technical Reviews or FTR. At the later stages (integration and acceptance), testing comes into picture.
