The aim of the software developer is to develop high-quality software within a specified time and budget. To achieve this, software should be developed according to the functional and performance requirements, document development standards, and characteristics expected from professionally developed software. Note that private metrics are collected by software engineers and then assimilated to achieve project-level measures. The main aim at the project level is to measure both the errors and defects. These measures are used to derive metrics, which provide an insight into the efficacy of both individual and group software quality assurance and software control activities.

Changes are implemented in the software system by following a software maintenance process, which is known as Software Maintenance Life Cycle (SMLC).This life cycle comprises seven phases, namely, problem identification, analysis, design, implementation, system testing, acceptance testing, and delivery phase.

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.

There are two basic approaches to testing: functional and structural. In functional testing   the structure of the program is not considered. Test cases are decided solely on the basis of the requirements or specifications of the program or module, and the internals module of the program are not considered for selection of test cases.

The software is tested at different levels. Initially, the individual units are tested arid once they are tested, they are integrated and checked for interfaces established between them. After this, the entire software is tested to ensure that the output produced is according to user requirements. There are four levels of software testing, namely, unit testing, integration testing, system testing, and acceptance testing.

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.

Lines of code and functional point metrics can be used for estimating object-oriented software projects. However, these metrics are not appropriate in the case of incremental software development as they do not provide adequate details for effort and schedule estimation. Thus, for object-oriented projects, different sets of metrics have been proposed. These 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.

This methodology refers to a set of well-documented procedures and guidelines used in the analysis, design, and implementation of programs. Coding methodology includes a diagrammatic notation for documenting the results of the procedure. It also includes an objective set (ideally quantified) of criteria for determining whether the results of the procedure are of the desired quality. The steps to use coding' methodology are listed below.

A test oracle is a mechanism; different from the program itself that can be used to check the correctness of the output of the program for the test cases. Conceptually, we can consider testing a process in which the test cases are given to the test oracle and the program under testing.
