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 dont 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)

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

  Opportunities
• of New Business
• Improved Member Retention
• More Less Paperwork and
• Revenue
  Administration Costs / Higher System
  Availability

• 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
