Can CAST-Computed Function Points be used for benchmarking?
Absolutely. Because CAST-computed function points are generated by a computable algorithm, they produce reliable, repeatable, consistent results time and again. There is currently no objective world-wide standard for measuring the output of AD or AM software teams. Because any non-computable standard requires expert human intervention, counts taken at two different times even within the same company’s portfolio can be difficult to compare objectively. The problem is exacerbated when such non-computable comparisons are made across companies and across industries. The consistency of CAST-computed function points makes it an ideal benchmarking standard. Because the count is made in exactly the same way, our customers (AT&T, AXA, Allianz among others) use it to quickly create a baseline benchmark against which changes in productivity can be readily measured. Benchmarking experts agree that these intra-company benchmarks are equally, if not more valuable to IT decision makers than external
