if we are ever to understand software productivity and use the measurements for estimating purposes, then we need a plausible, repeatable, technology-independent measure of work-output. The COSMIC method meets this need; sizes may be measured at any point in the life of a piece of software. It is up to each organization to determine the problem it is trying to solve and then decide for itself how and when to apply the COSMIC method and how to use the resulting measurements.
