1. 01/25/01 1 of 7 SAIC COTS-Based Systems (CBS) and Lifecycle Models (LCM) Tony Jordano Corporate Vice President for System and Software Engineering 2/7/01

2. 01/25/01 2 of 7 Agenda About SAIC Corporate Guidance for LCMs COTS-Based Systems and LCMs Concluding Thoughts

3. 01/25/01 3 of 7 About SAIC Science Applications International Corporation (SAIC) $5.5B Revenue - Half Government, Half Commercial 40,000 Employees Largest Employee-Owned Hi-Tech Company Business Sectors: –Criminal Justice –Energy - Oil & Gas & Utilities –Environment –Financial Services –Healthcare –National Security –Space –Telecommunications (including Telcordia Technologies) –Transportation & Logistics

4. 01/25/01 4 of 7 Corporate Guidance on Lifecycles Established Corporate-Wide Working Group in 2/99 Analyzed Wide Variety of Material and Experiences Identification, Definition and Selection Criteria for: –Waterfall –Incremental –Evolutionary –Spiral –COTS Integration –Automated Application Generation –Rehost/Port –Re-engineer –Maintenance Distributed in July 1999 NOTE: Consistent with IEEE/EIA 12207.2-1997

5. 01/25/01 5 of 7 CBS and Spiral (1 of 2) CBS - Typically For Commercial Clients –Very Common, Discussed As COTS Driven and RAD –40+ COTS Products in Some Systems (20+ Common) –6 Week to 6 Month Release Cycles Required –Time to Market and COTS Products Drive All Tradeoffs and Risk Considerations (Requirements Traded or Reprioritized) –Invarients 1-3 Apply, but Driven by COTS & Release Dates –Invarients 4-6 Have Less Application –Really COTS Driven LCM With Spiral Overtones

6. 01/25/01 6 of 7 CBS and Spiral (2 of 2) Spiral - Typically For Government Clients –Some Understanding of Spiral Exists –Broad Tradeoffs of Architecture, Performance, etc. »Requirements More Important Than In CBS –3 to 10 COTS Products in Deliverable Systems –All 6 Invarients Apply Broadly –Attempts with Fixed Price Contracts Reduced to Waterfall –Both Government PMO and Contractor need Domain Experience and Process Maturity –Really Spiral with Some COTS to Reduce Schedule & Cost

7. 01/25/01 7 of 7 Concluding Thoughts The 2 LCMs Could be Driven Closer Together –If Commercial Client Really Understands Spiral –If Government Client Really Wants COTS Driven First Spiral Cycles –COTS Survey, Initial Selection, and Function/Performance List –Obtain Selected COTS for Testing, Measurement, Trial Integrations, Determine Scalability, Interoperability, etc. »Define and Estimate Glue Code –COTS Selection, Function/Performance List, With Degree of Maturity, Scalability, Interoperability Considered »Then finalize Architecture and Release Schedule & Content »Plan Releases Based on Anticipated COTS Releases
