  1. The System Study Dr. Merle P. Martin CSU Sacramento

  2. Agenda • Waterfall Model • Preliminary Design Checklists • The System Study • Go / No-go Decision • The FHC Presentation

  3. Waterfall Model • Development process not really serial • May redo steps • Waterfall model of Systems Analysis • Figure 9-9

  4. Preliminary Design Checklists • Pages 303-307 • Output • Input • Files • Interactive screens • Processes

  5. Output • Make report look good • Include only fields needed • 80-position format • Print layout form (Figure 9-1)

  6. Input • Easy to use • Concise (only required fields) • Aesthetically pleasing • Machine-readable

  7. Files • Consolidate files with similar names • Not too much detail at this time • ERD • Data-element-to-file table (Figure 9-5)

  8. Interactive Screens • Well-balanced (e.g., spacing) • Not cluttered (20% rule) • Minimize use of color • Use highlighting (15%)

  9. Processes • Eliminate if don’t alter data • Consolidate similar processes • Make serial processes parallel • e.g., multiple form copies • Decouple processes • place data store between

  10. The System Study • Problem Statement • Existing System Documentation • project may be delayed • Problem Correction Alternatives • Recommended Solutions • Documentation • in appendices

  11. Go / No-go Decision • Possibilities • Rework • Scrap • Delay • Proceed with SDLC • Figure 9-9, page 314

  12. FHC System Proposal • Foundation Health Corporation existing systems: • PROMIS: memberships and renewals • PROGRES: price quotes • QCARE: medical claims / other customer service

  13. Proposal • Replace PROMIS and PROGRES with new system • Link to QCARE • Two phases • New system is Foundation Rating and Enrollment System (FARE)

  14. Today’s Systems Premium Accounting Quote Disks PROGRESS & Other Quoting Systems PROMIS Spreadsheets Q/Care IBM Mainframe Underwriting Spreadsheets Sales Under- writing

  15. Premium Accounting FARE Phase 1 (Eliminate PROGRESS) New Premium Accounting Interface Q/Care DB2 IBM Mainframe Sales FARE Under- writing

  16. Premium Accounting FARE Phase 2 (Eliminate PROMIS) Renewal Process New Premium Accounting Interface Q/Care DB2 IBM Mainframe Sales FARE Under- writing

  17. FARE Objectives • Multi-state, multi- product rating system • Step to paperless process • Manage work flows • Integrate info sources • FHC common look for proposals • Utilize existing technology • Enterprise-level database

  18. FARE Cost / Benefit • Cost reductions • Revenue enhancements • Alternatives • reengineer current system • in-house design new system • off-the-shelf product • culture eliminated outsourcing design • Tangible / Intangible matrix

  19. Benefits Grid Tangible Intangible Improve Profitability Cross-Selling Opportunities of New Business Improved Member Retention More Less Paperwork and Revenue Administration Costs / Higher System Availability Increase in Prospecting of New Business Elimination of Duplicate Accurate Rating (Single-Rating Data Entry Engine Concept) Less Costs Multiple Proposals / Improved Audit Process Improved Communication Improved Speed of Turnaround Rekeying of Proposals in Word

  20. Concepts to Remember • Preliminary Design checklists • System Study contents • Go / No-go decision
