The CAST Application Intelligence Platform enables users to measure Automatic Function Points from the source code of an application. CAST AIP measures the functional size of an application using OMG-compliant Automated Function Points and uses a default algorithm that is applied "out-of-the-box". You can find out more in CAST OMG-compliant Automated Function Points.
However, Function Points is a functional size measure that is based on the application's specifications and requires knowledge of the intent of the application's designers ("primary intent" mentioned in the OMG-compliant Automated Function Points Counting manual). So, to make the measure possible, Function Point Experts and Consultants need to calibrate the initial automatic count made by CAST AIP. Calibration includes:
- removing technical and temporary objects from the list of Function Points counted
- merging several function points into one (and unmerging)
- changing the type of the Data or Transactional Functions
Once calibration is complete, function point data can then be re-computed.
How does it work?
- The most recent snapshot data for a given Application or set of applications is displayed - OMG-compliant Automated Function Points and Transaction information is displayed
- You can then calibrate these results to your liking, by creating new rules, merging objects etc.
- Finally you compute the results to ensure new Function Point values are displayed (or generated a new snapshot)
What can you do with AIP Console?
At the current time, the following is possible with the AIP Console interface:
- View the number of valid/invalid transactions identified in the Application during the analysis/snapshot
- View detailed information about the number of transactions and data entities identified in the Application during the analysis/snapshot
- View detailed information about the rules (default and custom) used to identify Transaction entry-points, Data entities, Transaction end points and excluded items, including:
- The package providing the rule
- The number of objects identified by the rule
- Whether the package has been updated
- Whether the package is active or not
- Ability to create a new custom rule
- View the total number of Automatic Function Points (AFP) identified in the Application during the analysis/snapshot, including a breakdown for Transactional Functions (TF) and Data Functions (DF)
- View detailed information about the Transactional Functions (TF) and Data Functions (DF) identified in the Application during the analysis/snapshot
- Ability to edit each Transactional Functions (TF) and Data Functions (DF):
- change the type (ILF, EIF, EI, EO, EQ) and the value of each Data Function or Transactional Function that has been identified in the Application during the analysis/snapshot
- Delete, merge or unmerge Transactional Functions (TF) or Data Functions (DF)
- Change the counting mode used: AEP (default) or EFP (legacy)
Once calibrated, a compute function point action can be run to view up-to-date information based on the calibration that you have performed.
