Why Your Software Cost Estimates Change Over Time and How DevSecOps Data Can Help Reduce Cost Risk

White Paper
Early software cost estimates are often off by over 40%; this paper discusses how programs must continually update estimates as more information becomes available.

Program managers (PMs) must realize that early estimates are likely to be off by over 40 percent and that programs need to continually update estimates as additional information becomes available. It is important to understand how program risks can impact cost estimates. Tracking items—such as the decisions that have not yet been made, stability of the top capabilities needed, and measurements derived from the DevSecOps pipeline—can all help program management offices (PMOs) better understand program uncertainties that can impact estimates and help increase confidence in estimates over time.
