verification & validation

verification- are we building the product right

verification is a prevention activity.
verification can be done by reviews and walk through.

Verification is a process which involves Reviews and Meetings to evaluate documents, Plans, Code, Requirements and Specifications; this can be done with Checklists, Issues lists, Walkthroughs and Inspection meetings.

------------------

validation- are we building the right product
validation: it is the process of finding bugs to make sure
that the application is work under customer expectations.
validation is a correction activity.

Validation is nothing but execution of Test cases, a process to check whether the Expected and Actual results are same.
