metrics used in testing, The Product Quality Measures - 1. Customer satisfaction index, 2. Delivered defect quantities, 3. Responsiveness (turnaround time) to users, 4. Product volatility, 5. Defect ratios, 6. Defect removal efficiency, 7. Complexity of delivered product, 8. Test coverage, 9. Cost of defects, 10. Costs of quality activities, 11. Re-work, 12. Reliability and Metrics for Evaluating Application System Testing
Test Engineer and Test Lead will collect the software metrics.
Software metrics are numerical representation of some aspects of software or process of it's development
The structure of a software test plan : The testing process requirement traceability tested items testing schedule test recording procedures hardware and software requirements constraints Mahda Noura
Software testing is a cyclical process in which you: plan a test execute it identify bugs fix them test again During this process is you change the application or software you update the testing plan. This you have versions for the testing plan so that you can see what did the previous test check.

Having a lack of metrics, for software engineering, may cause issues for clients that require metrics for their business project. It is common in other engineering related disciplines to have metrics to show progress schedule and report. These metrics may aid in meeting deadlines and receiving payment. Not having them may cause issues in the future for software engineers and project managers.
Correct definition of metrics will help validate the goal of the software process and how that is being tracked
Metric is a measurement that can classify software or product quality and then process the quality of metrics. Matrix is a data collection mechanism, that uses collected data to derive metrics.
Software Development Life Cycle involves the complete Verification and Validation of a Process or a Project. Whereas Software Testing Life Cycle involves only Validation. Software Development Life Cycle involves business requirement specifications,Analysis,Design,Software requirement specifications,Development Process(Coding and Application development),Testing Process(Preparation of Test Plan,Preparation of Test cases,Testing,Bug reporting,Test Logs & Test Reports),Implementation and Maintainence . Whereas Software Testing Life Cycle involves Preparation of Test Plan,Preparation of Test cases,Testing,Bug reporting,Test Logs & Test Reports.
Use Metrics to Manage
One can effectively measure software quality by using metrics such as code complexity, code coverage, defect density, and user satisfaction. These metrics help assess the reliability, maintainability, and usability of the software, providing insights into its overall quality.
