What is the principal validation technique used in software engineering?

Code review by an independent team

Formal mathematical proof of correctness

Requirements walkthroughs with all stakeholders

Program testing, where the system is executed using simulated test data

Correct Answer

Program testing, where the system is executed using simulated test data

Explanation

Program testing — where the system is executed using simulated test data — is the principal validation technique. Because of the predominance of testing, the majority of validation costs are incurred during and after implementation.
