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

  2. Agenda • About SAIC • Corporate Guidance for LCMs • COTS-Based Systems and LCMs • Concluding Thoughts

  3. 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. 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. 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. 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. 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
