COSOSIMO* Workshop 13 March 2006 Jo Ann Lane University of Southern California Center for Software Engineering CSE Annual Research Review – March 2006 © USC CSE 2006 *COSOSIMO: Constructive System of Systems Integration Cost Model

Effective Human Factors © USC CSE 2006 CSE Annual Research Review Agenda Workshop objectives Review of scope of COSOSIMO Review of last workshop discussions COSOSIMO cost model parameters –Updated definitions –One more survey Case Study: View of COSOSIMO within the COCOMO Suite (if time permits)

Effective Human Factors © USC CSE 2006 CSE Annual Research Review Objective of March 2006 COSOSIMO Workshop To converge upon a relevant and complete set of parameters for the COSOSIMO model that –Are easily discerned in the early stages of SoS development –Minimal overlap with each other –Can be used to start cost model data collection activities

Effective Human Factors © USC CSE 2006 CSE Annual Research Review Scope of COSOSIMO Designed to estimate Lead System Integrator (LSI) effort associated with the development of net-centric systems-of- systems (SoS) Covers LSI types of EIA 632 activities with special emphasis on –Concurrent SoS scoping, planning, requirements, architecting –Source selection –Teambuilding, re-architecting, feasibility assurance with selected suppliers –Incremental acquisition management Development Integration and test –Continuous change, risk, and opportunity management

Effective Human Factors © USC CSE 2006 CSE Annual Research Review What is a “System-of-Systems”? Very-large systems developed by creating a framework or architecture to integrate –Existing systems –Systems currently under development –New systems to be developed SoS system components independently developed and managed Business Domain: enterprise-wide integration and sharing of core business information across functional and geographical areas Military Domain: dynamic communications infrastructure to support operations in a constantly changing, sometimes adversarial, environment SoS activities often planned and coordinated by a Lead System Integrator (LSI) Net-Centric SoSNet-Centric SoS

Effective Human Factors © USC CSE 2006 CSE Annual Research Review What is a “Lead System Integrator”? Organization (or set of organizations) selected to oversee the definition, development and integration of an SoS Typical activities –Lead concurrent engineering of requirements, architecture, and plans –Identify and evaluate technologies to be integrated –Conduct source selection –Coordinate supplier activities and validate SoS architecture feasibility –Integrate and test SoS-level capabilities –Manage changes at the SoS level and across the SoS-related IPTs Typically do not develop system components to be integrated (possible exception: SoS infrastructure)
