INTEGRATING BUSINESS PROCESS CONCEPTS INTO UML ACTIVITY MODEL

Abstract

The Unified Modeling Language (UML) activity model is widely accepted for modeling processes from pure technical views. Because it's rich high level design language and supported by standard body; OMG which involve most of top worldwide IT players. It turns out in modeling information systems, business processes are main component so needs suitable modeling language such as Business Process Model and Notation (BPMN) that is originated in organization domain. However, learning new language has the cost of learning curve. Since UML activity model has commonality with BPMN as both share the core principles of process modeling, this paper proposes sustainable change to UML activity model by introducing business concepts so technical modelers can speak with UML activity a different language. This synergistic relationship not only doubles the benefit of UML activity and reduces the learning curve, but also highlight the differences that add value to editor providers. A light weight extension or profile has been designed and evaluated using a real case study
