“…It does not, however, intend to point out the obvious. The drivers of cost increases and schedule delays are varied—it could be underestimating, both cost and the technical [Emmons et al., ], or lack of ability to perform to the targeted cost and schedule. Figure is a result studied by Emmons et al.…”

“…In 2007, NASA and Aerospace Corporation developed a cost and budget simulation tool, called the Sand Chart Tool (SCT) and used it in conjunction with Monte Carlo simulation to generate affordability analysis results. The results were then used to adjust projects' schedule and phasing accordingly to fit a portfolio of projects with the available budget [Emmons et al., ].…”

“…It is not a mathematical simulation of statistics. Instead, it attempts to model the actual cost and schedule performance [Emmons et al., ]. The purpose of SCT is to provide programs insights into cost, schedule, and risk performance at any given time for replanning and resetting objectives accordingly to fit projects portfolio with the remaining budget—which is aligned with the program management function.…”

Systems are becoming more complex while engineering of these systems is facing challenges in cost reduction and shortened schedules due to the fact that technologies emerge and quickly became obsolete. "Do more for less" is a new reality for the U.S. defense industry. As a result, large defense corporations have shifted their cost control effort from business to project management and systems engineering organizations. The realization of affordability in major weapon systems development programs may not be at a tipping point; however, the biggest customer of these weapon developers, that is, the U.S. Department of Defense (DoD), will drive affordability through contract estimation and performance on a firm fixed contract method. This becomes game changing in the defense contract industry, which will drive affordability from offices and manufacturing floors to supplier warehouses. For every complex system development program, the cost to design such system is estimated or predicted before the systems development and demonstration contract is awarded. The transformation of the estimated cost figure is evolving as systems engineering efforts taking place throughout the design life cycle. Thus, without understanding the cost figures during this time, the evolution of cost overrun is inevitable. This paper describes a method to assess the affordability maturity level associated with the systems engineering tasks defined by ISO/IEC 15288 and the Defense Acquisition Strategy, DODI 5000.02. The paper focuses on developing a methodology to insert and assess the maturity of systems engineering efforts and the integration of performance and cost measurement from concept definition through systems design and development. The method is called affordability maturity assessment methodology. C⃝
