Most estimates say that about 50% of thecostscanbeattributedtodefect detectionandremoval. Hence,thisisapromisingareafor cost optimisation. Various techniques can be used to improve thequality of software. Those techniques differ in many respects and it is consolidatedknowledgethatthebestresultintermsofdefect detectioncanbeobtainedbycombin ingseveraldiversetechniques.The main question in that context is then how to use those different techniques ina cost optimal way.
