Measure the Functional Size of a Mobile App: Using the COSMIC Functional Size Measurement Method

This paper describes a way the COSMIC measurement method could be applied to measure the functional size of mobile apps. Mobile apps are a fairly new type of software applications that are installed on mobile devices, usually a smartphone or a tablet. There are some important differences between traditional software applications and mobile apps, and these differences are the reason that a measurer has to make a number of assumptions and choices when doing the measurement. In this paper, these assumptions and choices are explained and the authors propose a way future COSMIC measurements of mobile apps could be carried out. In addition, an ´approximate´ method is proposed that can be used to size mobile apps in a fast and accurate way.
