IfSQ

Papers, Presentations and Books

Findings relevant to IfSQ Standards:

• A study of 450 routines found that 50 percent of highly cohesive programs were fault free, compared to only 18 percent of routines with low cohesion
• 46 percent of routines with no unused variables had no errors compared to only 17 to 29 percent for those with one or more unreferenced variables

IfSQ Defect Indicators:

• SP-4—Module Not Cohesive
  Routines which are cohesive are typically easier to modify, easier to fix and contain less errors than routines with diverse tasks.,
• DP-4—Unused Variables
  There are unreferenced variables in the code. Unreferenced variables are a strong indicator for other errors.
