How-estimation-in-TPPM-(-testing-process-performance-model- activity?

In testing PPM first of all estimate following things step by step

• Size of each Test Case (over all size and lenght of the every  test case is estimated)
• Defects of each Test Case(defects of the test cases are estimated)
• Efforts to execute each test case (Efforts are also are part of the estimates)

What-are-PPM-(process-performance-models)?

PPM

Process Performance Models are used to estimate and predict results to be achieved by following a process.

There are following process performance models.

• Effort Estimation Model
• Defect Estimation Model
• Time and Effort PPM
• Release Management PPM
• Patch Release PPM
• Testing PPM
