Applying Parametric Cost Models as a Predictive Parameter for CMMI Compliance

Parametrics Track



The Electronic Engineering Center (EEC) of Raytheon Space and Airborne Systems (SAS) recently breezed through a Capability Maturity Model Integration (CMMI) Level 5 assessment, jumping from an existing CMMI level 3 capability and without needing a separate CMMI Level 4 assessment in the process. Although this success was the result of a lot of hard work by many contributors, the bottom line is that there were very few changes in terms of business processes that were required to obtain a CMMI Level 5 organizational assessment, the hallmark of a learning and optimizing organization.

This paper discusses how the EEC incorporated parametric cost models as a predictive parameter into a functional organization’s standard business practices in a way that satisfied the requirements of CMMI’s Organization Performance Measures (OPM). This paper will introduce the 5 levels of CMMI compliance with a very brief overview.

The centerpiece of this paper will be how the EEC incorporated the standard business practice of understanding the productivity of electronics development and applying this understanding in such a way that achieving compliance with CMMI level 5 functional organization predictive requirements was relatively painless. This author has heard of many instances of organizations that performed certain OPM business practices in order to obtain CMMI level 5 compliance while then implementing them only during an assessment. The end result of these practices is significant wasted effort that must be replicated every appraisal period.

This paper will demonstrate how to apply what many savvy businesses are doing as a matter of sound business practices, namely understanding and tracking product productivity through parametric cost analysis, and applying this business process to comply with CMMI level 5 requirements.


David Bloom
After graduating from the University of California at Davis in 1983, Mr. Bloom has worked for the Naval Weapons Center, Lockheed Martin, Lawrence Livermore National Labs and since 2008, for Raytheon Space and Airborne Systems (SAS) where he is a Sr. Engineering Manager.
Mr. Bloom is currently the Cost Estimation Subject Matter Expert (SME) for the Electronics Center of SAS. He has developed parametric models for all Electronics Center products and helped transform the culture of the organization in the use of parametric bidding methodologies.
In addition to Mr. Bloom’s focus for the Electronics Center in developing parametric cost models for the design and development cycle activity of electronics sub-products, he is also leading the effort to reduce the cost of FPGA and ASIC development by modernizing the Digital Verification methods and establishing reproducible re-use methods.
Mr. Bloom has patents and a software copyrights along with a number of publications ranging from electromagnetic boundary value problems to cost estimation. In 2006, he won the International R&D 100 Award for innovating a cost effective Gigapixel Camera for persistent surveillance applications.

Current Position: Electronics Center Chief Process Engineer.
Master in Electrical Engineering from LMU, concentration in Computer Design.
Worked for Hughes / Raytheon for 34 years in various roles from test engineer, design engineer to systems engineer.

Robert P. Wright
Dr. Robert Wright joined Raytheon Space and Airborne Systems in 2003. Rob is currently the Director of Engineering Operations. In that role, he works across Engineering and with other functions to ensure the organization meets its goals, and that the organization is aligned for business success. Prior this, he served as the Director of Engineering Transition to Production from 2008 to 2011, where his focus was on ensuring development programs are transitioned smoothly to production.
He served as the Director for the Systems Verification Center from 2005 to 2008, where he provided expertise to SAS programs for all aspects of Test Architecture, Test Planning, Design Integration, Product Integration, Test Execution, System STE requirements, and Post-Delivery Support. Rob joined Raytheon in 2003 as the Operations Manager for the SAS Systems Engineering Center. In that role, he functioned as the deputy director, ensuring that the Center met its goals and ran smoothly.
Prior to his coming to Raytheon, Rob spent 17 years at The Aerospace Corporation, where he worked in a wide variety of roles. Rob began his career as a staff scientist developing advanced materials for focal plane arrays. He has developed telescope models for several space-based optical sensors, and was responsible for the maintenance of the Government Baseline (Air Force) Sensor Model for the Brilliant Eyes Program. He was the Mission Analyst for the SBIRS-Low program. He managed two different software groups: one focused on large-scale simulations, and another focused on simulations and firmware applications. His last position at The Aerospace Corporation was as a Senior Scientist, providing management of the Corporations IR&D project selection and execution, and working special projects for the Corporate Executives and Board of Trustees.
Rob received his Bachelors and Masters degrees in Physics, and his Ph.D. in Solid State Physics, all from UCLA.

Gary Bosworth
Gary P Bosworth joined Raytheon in 1980 as a Member of the Technical Staff for Hughes Aircraft Company, prior to the firms merger with Raytheon Company. He has held numerous positions of increased responsibility over the years including engineering functional manager, product line manager, IPT leader, program manager, and business line director. Bosworth’s engineering background includes systems engineering for airborne, naval/underwater, and automotive applications. He led the former Raytheon Consulting Group – Michigan, an engineering, information technology, and program management consulting services firm focused on the automotive industry.
In Bosworth’s current role as Director, Mission Assurance for Raytheon Space & Airborne Systems (SAS) business, he is responsible for driving organizational improvement to ensure customer mission success. Last year he led SAS’ successful pursuit for CMMI Level 5 rating covering systems, software, and hardware engineering for large development programs which was achieved two years ahead of plan Currently he is responsible to ensure savings supporting the business case associated with a large information management system deployment at SAS are realized.
Bosworth earned an MBA in general management from Michigan State University, a Master of Science in Ocean Engineering from the University of Southern California, and a Bachelor of Science in Engineering with an emphasis in ocean engineering from the University of Washington. Ocean Engineering is interdisciplinary encompassing study in mechanical, electrical, civil, and aerospace engineering as applied in the ocean environment.
