Verification process areas has to major parts and covers two techniques for verifying the product against the requirements. These are Peer reviews and internal testing.
Peer review is all about review of any project related documents (like - SRS, Design doc), codes review etc. It is considered as an informal procedure for verification, yet plays a vital roles in developing the product and helps in reducing the defects at the testing stage (verification).
In Peer Reviews, the reviewer is a PEER of the Author of the object (or document) to be reviewed, a person with the same skill and the same experience (technics, application domain...). It represent a different point of view and can help to find defects. I agree that is a Verification activity, but is not the same activity made in formal verification steps.
Perfoming Verification means - performing the testing in the testing environment as shared with the client. This is however, completely different from Validation. As validation talks about performing testing in the intended environment or client's environment. Verfication talks performing testing in the testing environment, i.e. internal testing. Verification is being performed by a different group of people, usally testing team and not by the peers and their objective is to verify the product against the actual client's requirement. It is being performed using test cases. Test cases are performed at the initial stage of the projects.
