Simple Parametric Model for Estimating Development (RDT&E) Cost for Large- Scale Systems
This paper summarizes OSD sponsored research regarding the development and implementation of a simple approach for estimating RDT&E cost. The approach is based on the systems engineering analysis data that is resident in system architecture products. The approach uses authoritative data that is normally available for ACAT I, II, and III programs, i.e., Information Support Plans (ISP), Department of Defense Architecture Framework (DoDAF) views, Selected Acquisition Reports (SARs), and Budget Exhibits.
The paper addresses the concept of interdependence and the architecture products, i.e., Nodes and Links, which capture the effects of interdependence. It describes the Nodes and Links modeling taxonomy, the selection of DoDAF views which provide the required data, the extraction of data, and the validation process used to insure data consistency.
The initial relationships of Nodes and Links to RDT&E cost are demonstrated. The concept of equivalent Nodes or Links, i.e., eNode and eLink, is presented. Finally, the improved relationships provided by eNodes and eLinks versus RDT&E cost are shown.
Paul Hardin is presently employed as Technical Director with Technomics, Inc. Mr. Hardin’s principal areas of expertise are methodology design and model development, including expert application of non-linear optimization techniques. Over the last several years, he has developed improved, innovative methodologies for high risk non-recurring acquisition cost elements (e.g., design engineering, software development and integration) and operating and support (O&S) cost elements. Mr. Hardin has played a key role in the development of two Navy cost tools, Operating and Support Cost Analysis Model (OSCAM) and Navy Visibility and Management of Operating and Support Cost (VAMOSC) VIEWS. Prior to accepting a position with Technomics, Mr. Hardin worked for the Office of the Secretary of Defense (OSD), Cost Analysis Improvement Group (CAIG) and the Naval Center for Cost Analysis (NCCA). Mr. Hardin graduated from the Georgia Institute of Technology with a Bachelor’s degree in Industrial Engineering in 1991 and received a Master’s degree in Systems Engineering from Virginia Polytechnic Institute and State University in May 1999.
Robert R. Jones is currently employed as a Senior Scientist and Cost Analyst with Technomics Inc. Prior to joining Technomics, Mr. Jones was employed by the Navy at the NSWC Carderock Division for thirty-three years. In January 2003, when he retired from the Navy, he was the Department Head of the Systems Engineering and Analysis Department. Mr. Jones has twenty-seven years of experience in cost estimating and economic analysis for the development, production, and operations and support of Navy technologies and systems; software cost estimating and cost model development; support for ACAT I program offices; preparing Independent Cost Estimates; participating in source selections; and, support for OSD cost and software data reporting activities. Mr. Jones graduated from the University of Rhode Island with a Bachelor’s degree in Mechanical Engineering in 1969, and he received a Master’s degree in Mechanical Engineering from the Catholic University of America in 1973.
Anna Irvine is presently employed as a Cost Analyst with Technomics, Inc. Ms. Irvine’s main contributions at Technomics have been associated with model and tool development in support of the LCS Mission Systems program, and research associated with analysis of DoDAF systems engineering information with regard to insight to development costs for systems. Prior to joining Technomics Ms. Irvine worked for NSWC Carderock Division as a cost analyst, and for AVID LLC as an Aerospace Engineer. Ms. Irvine graduated from Virginia Polytechnic Institute and State University in 1997 with a Bachelor’s degree in Aerospace Engineering and again in 2000 with a Master’s degree in Mathematics.
