A defect that could have been removed during the initial stage is later removed. What effect does this have on the cost? |
|
Answer» If a defect is discovered during the project's initial phase, it is important that the defect is removed during that phase rather than afterwards. The cost of fixing a defect increases greatly if it is delayed until a later stage in the development cycle. Following is a diagram showing how the cost of a fixing defect increases throughout the phases. It is more cost-effective to eliminate defects during the design phase, but it becomes twenty times more expensive to do so during maintenance. |
