Measuring Testing Effectiveness using Defect Detection Percentage

How good is your testing? Can you demonstrate the detrimental effect on testing if not enough time is allowed? Dorothy Graham discusses a simple measure that has proved very useful in a number of organizations-Defect Detection Percentage or DDP. Learn what DDP is, how to calculate it, and how to use it in your organization to communicate the effectiveness of your testing. From case studies of organizations that are using DPP, you'll find out the problems you may encounter and ways to overcome them.

• Learn what DDP is and how to calculate it using defect data you may already have
• How best to start measuring and using DDP
• Calculate DDP for different stages of testing (integration, system, user acceptance)
