Question

Illustrate defect spoilage and defect age?

Answer 1

Defect spoilage and Defect age metrics work with the same principle that is, how late you have found the defect. Defect age is also known as a phase age. The most important thing to consider in testing is that the more time we take to find a defect the more it will costs to fix it. So it is necessary to define the scale of the defect age according to phases.

After deciding the scale we can find the defect spoilage. Defect spoilage are defects from the earlier phase multiplied by the scale.
