Software metric

A software metric is a measure of some property of a piece of software or its specifications.

Since quantitative methods have proved so powerful in the other sciences, computer science practitioners and theoreticians have worked hard to bring similar approaches to software development. Tom DeMarco stated, “You can’t control what you can't measure.”

Common software metrics

Common software metrics include:

Limitations

It is very difficult to satisfactorily define or measure "how much" software there is in a program, especially when making such a prediction prior to the detail design. The practical utility of software metrics has thus been limited to narrow domains where the include:

  • Schedule
  • Size/Complexity
  • Cost
  • Quality

Too much emphasis on any one of these aspects of performance is likely to create an imbalance in the team’s motivations, leading to a dysfunctional project.

The Balanced scorecard is a one tool for managing a suite of metrics that address multiple performance perspectives.
