The process of evaluating software at the end of the software development process to ensure compliance with software requirements. The technique for validation is testing, inspection and reviewing.
Validation should always be considered in a software program. The amount of validation depends on what the program is doing, and how it is doing it. If the validation is a small percentage of the overall program then it doesn't matter much how efficient it is in terms of performance. There are good and bad ways (actually inefficient ways) to do validation. If you instrument a program and find that a significant portion of the time is spent in validation you may want to visit the algorithms used in the validation to see if there is a more effective way to do this. In some cases the performance of validation of data is very important; in other cases it is a side-effect.
Requirements validation is a critical step in the development process, usually after requirements engineering or requirements analysis. Also at delivery (client acceptance test).
upgradation of old softwares. e.g- anti-viruses. provides opportunities for new jobs and latest requiremants. provides better interfacing between hardware & software.

CMM verifies the quality of the overall software development process beginning from problem definition. Software validation and verification are the subitems of CMM.

Not clear what the question is about, please clarify
In validation testing, the test team seeks to ensure that each software function or performance characteristic conforms to its specification. In acceptance testing, the test team needs to ensure that the software works correctly for the intended user in his or her normal work environment.
Validation testing is to test software if it meets its stated requirements. System testing is the testing of Software and Hardware together and to find out they both can work together to be successful application.

Standard testing is more so based on judgment and can be adjusted through validation. Benchmark testing is multiple criteria for judging success.
Validation testing should ideally be performed by the software user, as they are best equipped to assess whether the software meets their needs and requirements in a real-world context. While software developers can conduct initial testing to ensure functionality and quality, user validation provides critical insights into usability and practical application. Involving users in the validation process can lead to more effective and user-friendly software solutions.
