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

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)
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
