Is quality assurance the process police?
SQA is often compared to the police, and it is correct to a certain degree as it also has this aspect of law enforcement. A good SQA implementation we would rather compare to a doctor, who makes a diagnosis, but also helps to cure the problem. And equally important, he would advise you how to minimize your risks in advance. Often, he is not given the chance to do so, because he gets involved too late, which is another common thing with SQA.
