In a comparison with similar industry projects, Callista has been rated consistently in the top 30% of companies when measuring development productivity. On some measures Callista is in the top 10% of companies.


A Function Point is a unit of measure of the business functionality of a system. These can be counted as a measure of the business functionality of a system irrespective of other characteristics like technology.


The International Software Benchmarking Standards Group (ISBSG) allows organisations to submit their function point counts and other project information for comparison to other like projects.


Callista recently submitted three projects to ISBSG for comparison. The diagram below shows the three projects in comparison to other projects with a similar technology.


The project Function Point Counts have been audited both internally and externally by a Certified Function Point Specialist (CFPS).


The ISBSG use a simple rating system to assess the completeness and credibility of the data supplied for use in productivity analysis. Callista was awarded an “A” rating on all three submissions made and feedback from the ISBSG Repository Manager indicated “The data submitted is complete for a positive assessment. Further data on other projects you may have would be very welcome.”


It should be noted that: “The ISBSG believes that the projects in the Repository are representative of the more productive projects in the industry, rather than industry norms. Only organisations that collect the necessary metrics, can contribute to the Repository. Organisations with software metrics programs are likely to be among the more mature software development organisations.”


To paraphrase, not only is Callista in the top 30% of companies for productivity but it is in the top 30% of the top companies and would well outperform the broader industry.
