This sounds simple, but it is a rare practice. The most common approach is to delay major testing until the final QA phase of software development, where defects are often discovered for the first time. Most bugs are not detected or fixed until long after their introduction. The longer a defect remains, the harder it is to fix.

On large software products, each stage of development that a defect survives will increase the cost of fixing the defect by ten to fifty times. A defect introduced in the design phase can cost hundreds of times more to fix in the testing phase than it would if fixed immediately after its introduction |
