Overview
Software quality metrics are used to measure the quality of software products, processes, and services. These metrics can be used to assess the effectiveness, efficiency, maintainability, reliability, and usability of the software.
Software Quality Metrics
Some of the software quality metrics are as follows:
- Code coverage
- Defect density
- Usability
- Cyclomatic complexity
- Mean time to failure
- Mean time to repair
- Maintainability index
Code Coverage
Code coverage metric measures the percentage of code that has been tested. A high code coverage indicates that most of the code has been tested, which increases the likelihood of finding bugs.
Cyclomatic complexity
Cyclomatic complexity metric measures the complexity of the code. A high cyclomatic complexity indicates that the code is more complex and difficult to understand, which can lead to more errors.
Defect density
Defect density metric measures the number of defects per line of code. A high defect density indicates that the code is more error-prone.
Maintainability Index
Maintainability index metric measures the ease of maintaining the code. A high maintainability index indicates that the code is easier to maintain.
Mean Time To Failure(MTTF)
Mean time to failure metric measures the average time between failures. A higher MTTF indicates that the software is more reliable.
Mean Time To Repair(MTTR)
Mean time to repair metric measures the average time it takes to fix a failure. A lower MTTR indicates that the software can be fixed quickly.
Usability
Usability metric measures how easy the software is to use. A high usability score indicates that the software is more user-friendly.
These metrics can be used to identify areas for improvement and to track progress over time. It is important to select metrics that are relevant to the software being developed.
