Pure object-oriented development requires that object-oriented techniques be used during the analysis, design, and implementation of the system. Various methods have been proposed for OOA and OOD, many of which propose a combined analysis and design technique.

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.

The development of software begins once the requirements document is 'ready'. One of the objectives of this document is to check whether the delivered software system is acceptable. For this, it is necessary to ensure that the requirements specification contains no errors and that it specifies the user's requirements correctly. Also, errors present in the SRS will adversely affect the cost if they are detected later in the development process or when the software is delivered to the user. Hence, it is desirable to detect errors in the requirements before the design and development of the software begins. To check all the issues related to requirements, requirements validation is performed.

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.

Software engineering shares common interest with other engineering disciplines. Like other engineering domains where a given problem (for example, building a bridge) can be solved by following a series of interrelated steps, the software development process also comprises a number of steps or phases. The main objective of software engineering is to develop methods for large systems, which help developers obtaining high-quality software in minimum time and at low cost. Therefore, it is essential to perform software development in phases. This phased development of software is often referred to as the software development life cycle (SDLC) or software life cycle.

As soon as the first iteration of architectural design is complete, component-level design takes place. The objective of this design is to transform the design model into functional software. To achieve this objective, the component-level design represents -the internal data structures and processing details of all the software components (defined during architectural design) at an abstraction level, closer to the actual code. In addition, it specifies an interface that may be used to access the functionality of all the software components.

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.

Software engineering employs a well defined and systematic approach to develop software. This approach is considered to be the most effective way of producing high-quality software. However, despite this systematic approach in software development, there are still some serious challenges faced by software engineering. Some of these challenges are listed below.

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