Uma abordagem para modelagem de software utilizando a OPM para desenvolvimento iterativo, incremental e ágil

Abstract

Modeling is one of the methodological activities in any software development process, mainly in the analysis and design phase. Usually the UML is used as modeling language, but it is criticized for being sprawling and complex. Informal visual conventions are also used, nevertheless, there is no single notation for the elements. OPM could be an alternative language because of its ability to express structure and behavior in a single diagram and complexity handling mechanisms. This paper presents a modeling approach using OPM in iterative, incremental and agile software development processes. The approach will intend to be not only complete, but easy to understand and apply. This approach was named PIASO, from the portuguese acronym for Iterative, Incremental and Agile Software Design using OPM. An evaluation of the approach was carried out by a group of professionals and the results show that the perception about the approach is that it is easy to understand and use. 67% out of the participants agreed that the approach is easy to understand and use and 33% agreed partially. In addition, the results show that the perception of the usefulness of the approach is positive, 56% out of the participants agreed that the approach is useful and 36% agreed partially. Finally, to illustrate the approach’s usage, a study case was performed, which indicated that for a software glance and architecture the PIASO was easy to execute and not time consuming, but to specify logical algorithms OPM diagrams are not so effective. Finally, PIASO’s iterative characteristic is naturally adapted to iterative, incremental, and agile software development processes.
