Design of a Functional Size Measurement Procedure for a Model-Driven Software Development Method*

The capability to accurately quantify the size of software developed with a Model-Driven Development (MDD) method is critical to software project managers for evaluating risks, developing project estimates, and having early project indicators. This paper presents a measurement procedure defined according to the last version of the ISO 19761 standard measurement method. The measurement procedure has been designed to measure the functional size of object-oriented applications generated from their conceptual models by means of model transformations. The measurement procedure is structured in three phases: the strategy phase, where the purpose of the measurement is defined; the mapping phase, where the elements of the conceptual model that contribute to the functional size are selected; and the measurement phase, where the functional size of the generated application is obtained.
