ROI: Impact of CMM Maturity onCost, Quality, Manageability

• Detailed measurement data on 90 projects was accumulated (over 9 years).

• Data included accurate product data (cost, defects, size, etc.) and process data (based on assessments).

• Analysis to determine correlation between process maturity and product data showed minimal correlation.

X axis determined by number of KPAs satisfied, partially satisfied, not satisfied

Conclusion: Extremely difficult to measure process impact
