Abstract
When it is going to apply quantitative management to a software development project, it is required to estimate size of the software. It is a function point to be representative as a standard of the scales. It is the IFPUG method to be representative in function point technique. The IFPUG method is the technique that spread widely, but there is the software that a measurement is difficult by the IFPUG method. The function point measurement technique that I can recommend to such a software development project is the COSMIC method. This article introduces the measurement technique of the COSMIC method and a point to keep in mind on applying it.
