Abstract—The system-level size measures are important in software project management as tasks such as planning and estimating the cost and schedule of software development can be performed more accurately when a size estimate of the entire system is available. However, due to the black-box nature of software components, traditional software measures are not adequate for Component-Based Systems (CBS). We have developed a Function Point (FP) like measure, named Component Point (CP), for measuring the system-level size of a CBS specified in Unified Modeling Language. In this paper, we present a theoretical validation of the CP measure using mathematics and show that not only the CP measure holds all the mathematical conditions necessary for a size measure, but it can also be used in Component-Based Software Development (CBSD) in a similar way that FP and its extensions are used in other software development paradigms.

Index Terms—Component-based systems, component point, software sizing, mathematical validation.
