Verification and validation are extremely important in the software development process. If you can't verify or validate a set of activities to ensure that the software is not implemented correctly, hasn't been built to specification or is functioning properly, then you will surely have problems with your production environment. Interviewers know how important this is, and will ask questions about it to make sure that you have a practice of doing your due diligence to ensure the highest quality software development. When questions come up about verification and validation, it might score you an extra point in the interview if you give the interviewer a history of how V&V was formed. It is actually an application of Six Sigma and its principles. Salesforce adopted the Six Sigma process early and offers its employees training and certification opportunities in this discipline. It was used to design products in the manufacturing and support process areas. It's important to remember if asked that there are two important aspects of software quality management. Verification gives the answer to the question whether software is being developed correctly, and validation provides the answer whether the right software is being produced.
