Web application functional size estimation based on COSMIC method and UWE approach
In the last years measuring functional size of software applications became one of the most popular methods when there is need for creating models for effort, costs and budget estimation in software development. Functional Size Measurement (FSM) methods quantify the software from its user's perspective, disregarding quality and technical criteria. In context of conceptual models where models represent application at higher level of abstraction, functional size of developed software application can be measured on the basis of conceptual model and requirements analysis. Requirements analysis is usually conducted thru usage of use case, sequence, activity and other UML diagrams. In this work, we have investigated possibility of using COSMIC FSM method for functional size estimation of web applications whose basic model is created using UML-based Web Engineering (UWE) approach. An example of developed web application with UWE requirements model used for COSMIC measurement is presented and discussed.
