We all know that the sooner defects are found, the easier and less expensive they are to fix. Relying solely on dynamic application testing to find defects isn’t the best or most efficient means of testing.  When requirements gathering begins, testing process can be launched immediately, without executing any code.  At this stage, defects cost nearly nothing to fix, as opposed to waiting until the issues hit the test or production environment, costing your company both time and revenue loss.
