2. Outline COSYSMO Drivers Data collection process
Data safeguarding procedures
Schedule & Critical Path

3. COSYSMO Introduction
Parametric model to estimate system engineering costs
Includes 4 size & 14 cost drivers
Covers full system engineering lifecycle
Developed with USC-CSE Corporate Affiliate and INCOSE participation

4. Update since Feb briefing in Tampa
Collaboration with:
SECOE/Eric Honour
DAU SoS effort/Rob Flowe & Martha Spurlock
Finalized new driver definitions
# of recursive levels in the design
Technology Maturity
Length of life cycle
Three potential data points
BAE Systems: Mission Solutions/Information Systems Sector (Jim Cain)
Raytheon: Strategic Imaging Systems/Intelligence & Information Systems (John Rieff, Gary Thomas)
NAVAIR: 4.X (Dave Burgess, Donald Allen)

6. Data will drive the Evolution Path & Scope of the Model
Operate, Maintain, or Enhance
Transition to Operation
Replace or Dismantle
Oper Test
& Eval
Conceptualize

Global Command and Control System
1. COSYSMO-IP
2. COSYSMO-C4ISR
Satellite Ground Station
Joint Strike Fighter
3. COSYSMO-Machine
Future Combat Systems
4. COSYSMO-SoS

7. 4 Size Drivers Number of System Requirements
Number of Major Interfaces
Number of Operational Scenarios
Number of Critical Algorithms
Each weighted by complexity, volatility, and degree of reuse

8. 14 Cost Drivers Application Factors (8) Requirements understanding
Architecture complexity
Level of service requirements
Migration complexity
Technology Maturity
Documentation Match to Life Cycle Needs
# and Diversity of Installations/Platforms
# of Recursive Levels in the Design

9. 14 Cost Drivers (cont.) Team Factors (6) Stakeholder team cohesion
Personnel/team capability
Personnel experience/continuity
Process maturity
Multisite coordination
Tool support

10. Data Collection Process
Project & people are identified
Systems engineer
Cost estimator/data base manager
Job/task codes in accounting system are
mapped to COSYSMO
Meta data is collected
System scope
Life cycle
Application domain
Cost drivers are rated
Interaction between SE, Cost, USC
Data is entered into secure repository at USC

11. Safeguarding Procedures
Data identification
Only affiliate & Dr. Boehm know the OID (XXX) and only affiliate knows PID (YYY)
Data storage
Stand-alone computer at USC with one-way access to the network
In a room with cypher lock & limited access
Data access
Non-disclosure agreements signed
Controlled access to data by researchers (US Citizens only)

12. How can the CAB help? (Assumptions from the Project Plan)
Identify potential sources for Systems Engineering data
Identify additional commercial INCOSE members for Working Group
Commit resources to assist with:
Driver definition and refinement
Review of outputs
Delphi survey participation
Data from projects
Help in obtaining lead participants from other INCOSE Corporate Members
Establish COSYSMO “owner” within INCOSE
Measurement Working Group willing
Assist USC in finding additional funding support for a COSYSMO dedicated graduate student performer

13. Parametric Cost Model Critical Path
Usual #
Months*
Critical Path Task
6 Converge on cost drivers, WBS
6 Converge on detailed definitions and rating scales
12 Obtain initial exploratory dataset (5-10 projects)
6 Refine model based on data collection & analysis experience
12+ Obtain IOC calibration dataset (30 projects)
9 Refine IOC model and tool
*Can be shortened and selectively overlapped
