SQA Extension Services-Prevention and Detection Process

There are two ways to deliver software free of errors. The first is to prevent the introduction of errors in the first place. And the second is to identify the bugs lurking in your code, seek them out and destroy them. Obviously the first method is superior. A big part of software quality comes from doing a good job of defining the requirements for the system you are building and designing a software solution that will satisfy those requirements. Testing concentrates on detecting those errors that creep in despite your best efforts to keep them out.

Defect prevention is the most vital but habitually neglected facet of software quality assurance in any project. If functional at all stages of software development, it can condense the time, overheads and wherewithal entailed to engineer a high quality product. The key challenge of an IT industry is to engineer a software product with minimum post deployment defects.

Defect prevention [DP] is a process of identifying defects, their root causes and corrective and preventive measures taken to prevent them from recurring in future, thus leading to the production of a quality software product. Hence, organizations should opt for defect detection and prevention strategies.
