FPA Steps for Files

Later in this document internal logical files and external interface files are discussed in detail.

FPA Steps

F1. Application documentation and file rules are used to identify files.

F2. The application documentation (transaction model and data model) is used to determine type of file (either external interface file or internal logical file).

F3. With the help of application documentation (data model) and file rules the number data elements and record element types are determined.

F4. Each identified file is assigned a value of low, average or high based upon type, data elements and record types.

F5. A distinct numerical value is assigned based upon type and value (low, average, or high).

F6. All files are summed to create a file unadjusted function point count.
