Schedule and Cost targets are typically optimistic (overruns)
Performance results vary widely.
Plans are based on known past performance. Estimates/plans are more realistic and met more often.
With well-defined processes, performance improves at Level 3.
Actual performance
With quantitative management of the process and product, performance continues to improve at Level 4.
With continuous process optimization and targeted technology insertion, performance continues to improve at Level 4.
