The International Space Station Management and Cost Evaluations Task Force Anthony A. DeMarco President, PRICE Systems, L.L.C. 17000 Commerce Parkway - Suite A Mt. Laurel, NJ 08054 [email protected] 856.608.7214 Introduction The NASA-led International Space Station (ISS) is a technological marvel and a great feat of international cooperation. The ISS is an Earth-orbiting laboratory drawing upon the scientifi c and technological expertise of 16 nations: the United States, Canada, Japan, Russia, Brazil, and the 11 member nations of the European Space Agency (ESA). The ISS is a gateway to new space frontiers, a hallmark to United States space leadership, a unique laboratory, and a virtual space classroom. The ISS also is an out-of-control project, one that needs an immediate managerial overhaul to assure its productivity and retain its promise of being a world-class orbiting laboratory. The project is a victim of inadequate cost-accounting measures, a skyrocketing price tag, and an increasingly suspect research agenda given cost overruns and shrinking crew size. All these issues help frame the program as one steeped in controversy rather than as a cosmic gateway to the universe. ISS Cost Growth Revelations at the start of 2001 pointed to a $4.8 billion growth in NASA’s part of the program. That raised the cost to complete the ISS to a projected $30.1 billion. The escalating number is one that NASA, Congress, and other budget-watchers fear will grow. Furthermore, it was estimated that the outpost would cost on the order of $1.5 billion a year to operate. -

Presented at the 2007 ISPA/SCEA Joint Annual International Conference and Workshop - www.iceaaonline.com System of Systems Cost Estimating Solutions Josh Wilson PRICE Systems, LLC Presented at the 2007 ISPA/SCEA Joint Annual International Conference and Workshop - www.iceaaonline.com System of systems is a relatively new term being applied to capability driven projects addressing large, inter-disciplinary problems involving many systems at multiple levels and multiple domains. Being poorly understood overall, it is not surprising that the tools and thought processes needed to address such problems are incomplete. The need to solve system of systems problems is urgent not only because of the growing complexity of modern challenges, but also because system of systems problems involve decisions that commit large amounts of money and resources. Fortunately, an area in which several advocates are attempting to improve industry understanding of system of systems relates to estimating the cost and effort required to deliver capabilities rather than platforms. Currently, the significant offerings in this and closely related realms include COSYSMO, COSOSIMO, SECOST, SEER-H with TSV, PRICE PES, and PRICE TruePlanning Systems. This paper explores the history of each of these models, the origin of their methodologies and cost estimating relationships, the major size and cost drivers, and the extent to which each solution addresses the need for a system of systems estimating capability. But first, what exactly is a system of systems? Maier’s Criteria for defining a system of systems has probably been encountered by anyone spending at least a few minutes looking into the subject. There are a few additional characteristics that often appear, but for the most part a system of systems may be classified as such by exhibiting a majority of the five traits listed by Maier: Operational Independence, Managerial Independence, Evolutionary Development, Emergent Behavior, and Geographical Distribution.
