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 Design: It is the first step in moving from problem domain to solution domain. The purpose of the design phase is to plan a solution of the problem specified by the requirements document. Starting with what is needed, design takes towards how to satisfy the needs.

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.

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.

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 .

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.

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.

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.

Software testing can be performed either manually or using automated testing tools. In manual testing, test cases are generated, the software is executed, and the result produced is documented manually. Hence, manual testing is considered to be costly and time-consuming. To reduce the time and cost, automated testing is used. There are many testing tools available that are useful in several places while testing software product. These tools can be categorized as static testing and dynamic testing tools.
