This question already has an answer here:
I am working on a project and my task is to evaluate quality of that project by quality metrics. I found three types of metrics namely product, process & project. On some websites I fount other types like Defect Detection Percentage, Defect Removal Efficiency, Defects Find Rate, Escaped Defects Found, Function Points, Lines of Code, Mean Age of Unresolved Defects, Mean Time to Fix, Resolved Defects metrics, etc .
So my question is which are the right types of metrics and how do I get that I should use X type of metrics for calculation(My project is in .NET). Also help with the names of freely available tool.
