The task of verification, from my own experience, is somewhat complex compare to the design itself, and involves techniques which can be described as wierd to common design methodology. In fact, what is important, as any enginering job, is the result, and here the result is a proof that the design complies to the requirements.

Formal methods differ from other design systems through the use of formal verification schemes, the basic principles of the system must be proven correct before they are accepted [bowen93]. Traditional system design has used extensive testing to verify behavior, but testing is capable of only finite conclusions.

Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] in the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.

In other words, software verification ensures that the output of each phase of the software development process effectively carry out what its corresponding input artifact specifies (requirement - design - software product), while software validation ensures that the software product meets the needs of all the stakeholders (therefore, the requirement specification was correctly and accurately expressed in the first place).
