Keep Improving MAS Method Fragments: A Medee-Based Case Study for MOISE+

Continuous improvement is a procedure to improve products, services or processes. In the Software Engineering domain, software process improvement means understanding existing development processes and changing them to increase product quality and reduce development costs and time. In this paper, we present the Medee Improvement Cycle, which adopts this approach to improve development methods for Multiagent Systems (MAS). Such a cycle is anchored in the Medee Method Framework, which provides means for building methods through the combination of method fragments sourced from existing Agent-Oriented Software Engineering methods (AOSE methods) and Agent Organization models (AO models). The Medee Improvement Cycle allows to continuous evolving MAS methods and fragments, taking into account a set of quality attributes, such as understandability, visibility, supportability, acceptability and robustness. We have shown through the case study how to apply this cycle to evolve fragments through their usage, instead of assuming that we have already the definitive version of them from the beginning.
