Improving Program Affordability Through The Application of Data Analytics

Parametrics Track



In the current budgetary environment, program affordability is a key concern. Improving program execution and minimizing schedule delays and cost growth are keys to improving program affordability. However, there is a lack of quantitative analysis of schedule risks, and a lack of understanding of the root causes for schedule delays and cost growth. Consequently, most of the common affordability improvement suggestions centered on relaxation of test and verification requirements, and streamlining of engineering processes may not address the true root causes. The effectiveness of these affordability improvement suggestions is uncertain.

Prior research results on statistical analysis of cost growth data by (Smart 2011, 2010) based upon a data set of development cost growth for 289 NASA and Department of Defense programs and projects suggested that cost growth data can best be described by “fat-tail” distribution, specifically, the Log Normal Probability Distribution. More recent research results by (Wang 2012) showed that similar “fat-tail” distribution behavior can also be observed in post Critical Design Review schedule performance data of individual programs.

In this paper, we will present our new research across multiple ACAT-1 programs showing that the “fat-tail” distribution behavior of schedule delays is applicable to hardware oriented programs, as well as software intensive programs. Further, our analysis shows that schedule delays do not behave like a “fat-tail” distribution at the early stage of a program. We will show that statistical analysis of program execution performance data at the “back-end” of a program life cycle can be further correlated with the statistics of program execution performance data from the “front-end” of a program life cycle to identify specific areas of improvement in the system engineering process that might significantly improve the program affordability.
