•Costs of test planning and preparation
•Costs of test execution, defect tracking, version and change control
•Costs of diagnostics, debugging and fixing
•Costs of tools and tool support
•Costs of test case library maintenance
•Costs of testing & QA education associated with the product
•Costs of monitoring and oversight by the QA organization (if separate from the development and test organizations)
11. Re-work
•Re-work effort (hours, as a percentage of the original coding hours)
•Re-worked LOC (source lines of code, as a percentage of the total delivered LOC)
•Re-worked software components (as a percentage of the total delivered components)
12. Reliability
•Availability (percentage of time a system is available, versus the time the system is needed to be available)
•Mean time between failure (MTBF).
•Man time to repair (MTTR)
•Reliability ratio (MTBF / MTTR)
•Number of product recalls or fix releases
•Number of production re-runs as a ratio of production runs

Metrics for Evaluating Application System Testing:
Metric = Formula
Test Coverage = Number of units (KLOC/FP) tested / total size of the system. (LOC represents Lines of Code)
Number of tests per unit size = Number of test cases per KLOC/FP (LOC represents Lines of Code).
Acceptance criteria tested = Acceptance criteria tested / total acceptance criteria
