Coupling-to-Cohesion ratio inversely correlated to errors

Research Finding:
Given a sample of 450 routines, the routines with the highest coupling-to-cohesion ratios had 7 times more errors than those with the lowest ratios.

IfSQ Defect Indicators based on this finding:

SP-4—Module Not Cohesive
Routines which are cohesive are typically easier to modify, easier to fix and contain less errors than routines wth diverse tasks.
