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.

Omission: - is a common error in requirements. In this type of error, some user requirements are simply not included in the SRS The omitted requirement may be related to the behavior of the system, its performance, constraints or any other factor.

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.

Analysis of programs by methodically analyzing the program text is called static analysis. Static analysis is usually performed mechanically by the aid of software tools. During static analysis the program itself is not executed, but the program text is the input to the tools .

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.

In control flow based and data flow based testing the focus was on which paths to execute during testing. Mutation testing does not take a path-based approach. Instead it takes the program and creates many mutants of it by making simple changes to the program.

1.  Development time problem:


Some large systems take so long to develop that the technology (computer, software, hardware components) changes between the time the system is first conceptualized and the time it is ready for delivery to the user.

Software maintenance involves modifying the existing software system and recording all the modifications made to it. For this, various maintenance tools are used. One of the commonly used maintenance tool is text editor. This tool creates a copy of the documentation or the code. The key feature of this tool is that it provides a medium to roll back (when required) from the current version of a file to the previous one. Several other tools used in software maintenance are listed in Table.

Many techniques for verification aim to reveals errors in the programs, because the ultimate goal is to make programs correct by removing the error. In proof of correctness, the aim is to prove a program correct. So, correctness is directly established, unlike the other techniques in which correctness is never really established but is implied by absence of detection of errors.

The primary goal of the coding phase is to translate the given design into source code in a given programming language, so that code is simple, easy to test, and easy to understand and modify. Simplicity and clarity are the properties that a programmer should strive for.
