Output
Make report look good
 Include only fields needed
 80-position format
 Print layout form (Figure 9-1)

Input
Easy to use
 Concise (only required fields)
 Aesthetically pleasing
 Machine-readable

Files
Consolidate files with similar names
 Not too much detail at this time
 ERD
 Data-element-to-file table (Figure 9-5)

Interactive Screens
Well-balanced (e.g., spacing)
 Not cluttered (20% rule)
 Minimize use of color
 Use highlighting (15%)

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

FHC System Proposal

Foundation Health
Corporation existing systems:
PROMIS: memberships
and renewals
PROGRES: price quotes
QCARE: medical claims / other
customer service
Proposal
Replace PROMIS and
PROGRES with new system
 Link to QCARE
 Two phases
 New system is Foundation Rating
and Enrollment System (FARE)
