Scrum and Metrics

Metrics

• There are many code metrics, some of them measure code quality and others just prepare information about code situations.

Metrics and Quality

• Metrics that measure code quality :
  • Class Coupling / Module Coupling
    • Afferent Coupling
    • Efferent Coupling
    • Cohesion
  • Cyclomatic Complexity
  • Depth of Inheritance
  • Function points
  • Instability Index
  • Maintainability Index
• Metrics that do not measure code quality :
  • Code Coverage
  • Lines of Code (LOC)

Code Metrics Synonyms

• Many code metrics have synonym as following :
  • Class Coupling : Coupling Between Objects (CBO)
  • Efferent Coupling (Ce) : Outgoing Dependencies
  • Afferent Coupling (Ca) : Incoming Dependencies
  • Cyclomatic Complexity : Program Complexity
  • Depth of Inheritance : Depth of Inheritance Tree (DIT)
  • Lines of Code (LOC) : Source Lines of Code (SLOC)
