Case Study: SITINA - A Software Engineering Project

This paper presents a case study based on a complex software engineering project that took place in a Portuguese SME, Small to Medium sized Enterprise. Our initial goal was to evaluate and adapt Software Engineering theory to the reality of SMEs, usually working in chaotic environments, and following no standard method. We refer to such absence of method as the just do it process model. We shortly present the project, critically discuss its results, and summarise what we believe has been learnt from the experience. We will consider the highly interactive collaboration model, evolutionary prototyping model, object-oriented A&D methods, and CASE tool support. We will discuss its theoretical principles and evaluate its expected advantages and shortcoming on the project mentioned. Finally we propose a new model for evolutionary prototyping, better adapted to the reality of the environment we faced.
