  1. COSOSIMO Constructive System of Systems Integration Cost Model (COSOSIMO) Workshop November 7, 2006 ******************Outbrief Jo Ann Lane jolane@usc.edu University of Southern California Center for Systems and Software Engineering

  2. Agenda • COSOSIMO tutorial • Discussion of System of Systems Engineering (SoSE) • Is it really different from traditional systems engineering with respect to cost estimation? • If so, how? • People talents/skills profiles? • New or modified processes? • Technology/product characteristics? • SoSE Survey – review and comment

  4. COSOSIMO Tutorial Overview • COSOSIMO Background • How COSOSIMO fits into the COCOMO suite • Methodology being used to develop model • Goal of COSOSIMO – to complement other COCOMO cost models • History of COSOSIMO • System of Systems (SoS) and SoS Engineering (SoSE) Environment • What is an SoS – COSOSIMO definition based on definitions by Mark Maier and Andy Sage • What is an LSI – looks at typical activities performed by organizations responsible for development of an SoS • What is SoSE – Key definitions provided by USAF Scientific Advisory Board on SoSE, National Centers for Systems of Systems Engineering, and Wikipedia • Comparison of SE to SoSE – summary of differences between traditional SE and SoSE as well as SoSE challenges gleaned from recent SoSE conferences and workshops

  5. COSOSIMO Tutorial Overview (continued) • COSOSIMO Tutorial • Current COSOSIMO Cost Estimation Approach • Overview of COSOSIMO 3 sub-models and their associated parameters • Planning, Requirements Management, and Architecting (PRA) • Source Selection and Supplier Oversight (SO) • Integration and Test (I&T • More detailed parameter descriptions can be found in USC-CSE-2006-606 (see http://sunset.usc.edu/csse/TECHRPTS/) • Conclusions • Summarizes SoSE observations and planned COSOSIMO direction • Expected COSOSIMO availability (depends on data availability): Fall 2007 • References • COSOSIMO-related • SoSE-related

  6. What is Needed to Support Fall 2007 Availability • Participation in current SoSE surveys • Data from both SoS and SE programs • Process descriptions to help understand the differences between SoSE and SE • Effort data to calibrate COSOSIMO (either standalone model or special calibration of COSYSMO) For those organizations that provide SoSE effort from at least 3 SoS projects, a local calibration will be provided…

  7. SoSE Discussions: General Recommendations/Areas for Further Research • Should consider operations costs vs. development cost tradeoffs • Can the model, via DoDAF, help you conceive the scope of the system and subsystems?  A raw number (for the size drivers) does not capture nested complexities • Need to look at Service-Oriented architectures • See Cancer Biomedical Informatics Grid (caBIG) https://cabig.nci.nih.gov • Uniqueness of SoSE…is this simply a state of mind that reflects the traditional systems engineering discipline but packaged in a more formal way? • Should look at effort required to develop SoS-specific vocabulary

  8. Review of SoSE Survey • New survey developed to better understand SoSs and SoSE • Key parts to survey • Survey participant information – want to interview key SoSE technical managers/engineers • SoS program characteristics • SoS characteristics and properties • SoSE characteristics • SoSE life cycle model • SoSE process model description • Success of SoS • Reasons for success • Reasons why not so successful • What else is important • Recommendations from workshop attendees to be incorporated into the next update
