Level 2: Detailed Linked Count

Level 2 Detailed Linked Count Description

A detailed linked count includes the following:

• application boundary is defined
• full functional decomposition to transaction level
• all files and transactions within scope are uniquely identified
• all files and transactions are classified according to type
• all files and transactions are accurately categorised according to complexity (DETs and FTRs are identified within IFPUG ranges where possible)
• all related files and transactions are linked (aids in assessing impact of change requests)
• explanatory notes are attached to files and transactions where necessary
• count is recorded and reported using the SCOPE Project Sizing Software^® software repository tool

Level 2 Count Attributes

Detailed Linked Counts are:

• very detailed
• easily auditable
• accurate (within the limits of the FPA technique +/- 10%)
• very well documented
• easily maintained

Best suited for the following count purposes:

• benchmarking projects (new development and enhancement)
• detailed estimates
• project tracking
• as detailed baseline model for future detailed enhancement project counting

Issues:

• time intensive – counting rates up to 250 fps per day
• rarely cost effective for large, legacy application baseline counts

Pre-requisites:

• good to high quality system documentation
• data model
• full access to system experts
