Constructive System of Systems Integration Cost
Model (COSOSIMO) Workshop November 7, 2006
Outbrief

• Jo Ann Lane jolane_at_usc.edu
• University of Southern California
• Center for Systems and Software Engineering

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

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 (IT
• More detailed parameter descriptions can be found
  in USC-CSE-2006-606 (see http//sunset.usc.edu/css
  e/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

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 SoSEis 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

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
