In earlier times, software was simple in nature and hence, software development was a simple activity. However, as technology improved, software became more complex and software projects grew larger. Software development now necessitated the presence of a team, which could prepare detailed plans and designs, carry out testing, develop intuitive user interfaces, and integrate all these activities into a system. This new approach led to the emergence of a discipline known as software engineering.

Developing methods that can produce high-quality software is another fundamental goal of software engineering. We can view quality of a software product as having three dimensions:

There are a few techniques available to verify that the detailed design is consistent with the system design. The focus of verification in the detailed design phase is on showing that the detailed design meets the specifications laid down in the system design. The three verification methods we consider are design walkthrough, critical design review, and consistency checkers.

It is believed that only by improving the process can be quality & productivity be improved. Process improvement required understanding the current process & its deficiencies & then taking actions to remove the deficiencies. This is possible only if the current process is under statistical control.

Once the software is developed it should be tested in a proper manner before the system is delivered to the user. For this, two techniques that provide systematic guidance for designing tests are used. These techniques are discussed here.

The activities in the management process for a project can be grouped broadly into three phases.

Function points are one of the most widely used measures of software size. The basis of function points is that the "functionality " of the system that is; what the system performs, is the measure of the system size. In function points, the system functionally is calculated in terms of the number of function it implements, the number of inputs, the number of output etc.

On successful culmination of software testing, debugging is performed. Debugging is defined as a process of analyzing and removing the error. It is considered necessary in most of the newly developed software or hardware and in commercial products/ personal application programs. For complex products, debugging is done at all the levels of the testing.

Because requirements specification are formally in people 's minds, requirements validation must necessarily involve the clients and the user. Requirement reviews, in which the SRS is carefully reviewed by a group of people including representative of the clients and the users, are the most common methods of validation.

The V model is useful in every phase of the software development life cycle. This model determines the complex relationship between each phase of the software development and ensures that each phase of software development is associated with testing. Various functions performed by V model are listed below.
