External Output Example

The following is a simple external output example.   While it may seem that counting function points is a long and a tedious process with proper training you could count thousands of FP's per day.

The following EO has 3 data elements (DET's) and references 4 FTR's (file types referenced) and would be rated as an Average and valued at 5 unadjusted function points.

The Amount data element is a calculated value (derived data) and you would not be find it on any FTR.  The description and due date data element (or fields) could be found on FTR's.  What makes this an EO is the calculated values.

When the application is invoked the reminder message is automatically displayed if any items "due."  This type of message that is "automatically displayed is often referred to as a notification message. 

Due date is not displayed, in this example, but  it is counted as a DET because it could be displayed under the right circumstances.

We offer comprehensive training on Function Points and Software Metrics.
