Many companies and organizations have achieved performance excellence as measured by increased productivity, improved quality, better control of projects, reduced cycle time and decreased costs through using the SEI CMM^® as a guide for process improvement. Organizations typically report productivity improvements of 10-50% and a return on investment of 4:1 (cost savings realized vs. process improvements dollars invested). Here are some example benefits.

• Projects delivered on time increased from 95% to 99.9%
• Effort hours per defect repair reduced 24%
• Cost to find and fix defects reduced 22%
• Overhead rates reduced by 7.3%
• Defect containment improved 13%
• Productivity up 25.2%
• Software development cost reduced by 28%
• Cost savings to customer in a cost-plus contract rose from 5.7 $M to 7.1 $M (25%)
• Software unit cost reduced 22%
• Median schedule variance improved from -15.8% to almost zero.
• Overall cost of quality reduced by over one third, 34.85%
