Shift Life & Defect Cost

Shift left is a software development approach that emphasizes the importance of early testing in the development process. It involves shifting testing activities to the left of the development process, so that they are performed earlier and more frequently. The goal of shift left is to identify and fix defects as early as possible, which can reduce the overall cost of testing and improve the quality of the software.

Defect cost is a measure of the financial impact of a defect on a software project. It can be calculated by adding up the costs associated with identifying, fixing, and retesting the defect, as well as any other costs that may be incurred as a result of the defect, such as lost productivity or lost revenue.

By adopting a shift left approach and minimizing the number of defects that are found in the software, organizations can reduce the overall defect cost of their projects and improve the quality of their software.
