Functional Size Measurement
Organizations pay large sums of money to have external companies benchmark their IT infrastructure. Application development, maintenance and support is often beyond the scope of these benchmarks. Ironically, the amount of money spent on these activities is, for many organizations, more than 50% of the total IT spend. The functional size of applications enables the calculation of valuable, benchmarking metrics. They include: Project Delivery Rate, Cost Efficiency, Delivery Speed and Value Delivered. These metrics can be compared against metrics, for similar projects, from the ISBSG Data Repository. The results of these comparisons can then used as a basis for improvements in cost and productivity for projects. This short paper delves into the world of functional size measurement, providing insights into the power of implementing and using it.
