A case study in COSMIC functional size measurement: The rice cooker revisited

Abstract

UML models have been successfully used to support COSMIC-based functional size measurement. UML-based measurement is of great interest for industry, because of the popularity of the language. However, industry needs well defined, easy to learn and apply methods. It is therefore necessary to provide measurement procedures that are well defined, that require relatively little effort and that are coherent with the COSMIC measurement rules, in order to ease their adoption in enterprise environments. This paper contributes to such goal: we show how to build UML models that are easy to measure according to the COSMIC rules; we provide a case study based on the well-known example of the rice cooker; we show how the usage of UML can actually improve the practice of COSMIC measurement, by making the COSMIC measurement rules applicable in a UML context. © Springer-Verlag Berlin Heidelberg 2009.
