Level 5: Rough Count
A rough count includes the following:
- application boundary is defined
- functional decomposition (3-4 levels only)
- transactions and data functions ‘tallied’ from menus, menu access paths, file lists, screen lists, report lists, application boundary
- diagrams, system interface documentation
- assumptions documented in count report
- count is recorded and reported using the SCOPE Project Sizing Software® software repository tool
Level 5 Rough Count Attributes
Counts are:
- low detail
- less accurate (+/- 20 - 25%)
- documented (issues and assumptions)
- ‘Skeleton’ on which enhancement counts can be built
- needs to be refined over time
Best suited for following count purposes:
- portfolio baseline assessment
- benchmarking support ratios
- as a baseline model for future enhancement project counting
- cost effective for large, legacy application baseline counts
Issues:
- very efficient – counting rates can exceed 750 fps per day
- cost effective for large, legacy application baseline counts which have very little enhancement
Pre-requisites:
- summarised system documentation
- full-time access to system experts (for the duration of count)
SCOPE and Level 5 Counts
Level 5 counts are done in SCOPE using the Multiplier in the Process Details and Data Group Details screen.
