CMM verifies the quality of the overall software development process beginning from problem definition. Software validation and verification are the subitems of CMM.
verification: Are we doing the right system? validation : Are we doing the system right?
Requirement Engineering Planning Software Design Validation and Verification [Testing] Software Maintenan
A structured set of activities required to develop a software system. Specification Design Validation Evolution
Neither, it should be performed by a qualified Software Tester and witnessed by a Software Quality Engineer, a Systems Engineer, and the customer/user representative. The Software Developer should be entirely out of the picture at this point and only be responsible for fixing bugs found during validation.

Validation is the term used in the Software Engineering in the development cycle of a software. Validation refers for answering the question "are we building product right?". i.e) to check whether we are building the product in the exact way which we have designed with the requirements and checking whether all the requirements and constraints for the product are satisfied.
To validate a machine, you typically run tests to ensure that it performs according to its specifications and complies with regulatory requirements. This process may involve performing functional tests, environmental tests, and validation of software and hardware components. Validation is important to confirm that the machine functions safely and effectively for its intended purpose.
Software validation is always based on the initial research's requirements and plans. The software can only pass the quality assurance test if it fulfills the requirements, the development stages correspond to the plans, and the documentation covers the software precisely.
unit ,integration, validation then system
software is process to finding error ,bugs and validation against requirement.testing involves operation of the system.
AnswerSoftware is just a lot of lines of code (numbers, letters and symbols that direct your computer). Therefore many people can manipulate software and use it without paying for it. Here in America we tend to obey copyright laws. However, in many other countries such as China it is common for people to distribute illegal copies of software. Software validation checks to see if they copy of software you are using has been tampered with. Microsoft has a Windows validation tool and if it discovers that you obtained Windows illegally than you will not people able to use Windows update. Software validation will never go away but neither will the people distribute illegally manipulated software.
