Nesma is very proud to present the Chinese version of the Nesma counting guidelines. In a world where standards are becoming more and more important, I am very pleased to see that in China people acknowledge this and are willing to study how to measure the functional size of software. Sizing the software in a standardized, objective, repeatable, verifiable and therefore defensible way opens up your world to software metrics! Metrics based on Nesma function points, such as Productivity (hours per FP), Cost efficiency (Cost per FP), Velocity (FP per month) and Project Quality (Defects per 1000 FP) can now be measured over time and compared between teams, departments, and organizations! Software becomes measurable and the output of software development teams can be measured objectively. By measuring functional size you can improve all kinds of processes: estimation accuracy can increase up to 60%! Performance measurement of external suppliers can bring you millions of dollars of benefits every year. Measuring functional size is really the basis for any software development improvement program, either in traditional teams and in agile or DevOps teams. Especially if this is combined with the software project data of the International Software Benchmarking Standards Group (ISBSG). Please use these counting guidelines, that contain dozens of years of practical experience, to measure the functional size of software development so that it becomes possible to demonstrate business value to your customers based on facts and data…not on opinions.
Kind regards,
