Software Process Definition and Modelling

POEML: a Process Orchestration, Execution, and Modeling Language

“…Many SPMLs are rich in terms of concepts and modeling elements, but this richness is their first weak point. This fact "puts the accent" on two aspects 27 that impact users efficiency when using an SPML. 24 First, the richness makes it difficult for process designers to learn the SPML.…”

“…Indeed, a coarse-grained model is useful to give an overview of a process, while a more fine-grained model gives the details expected for its execution. 27 It is important to propose an SPML that is as simple as possible but as complete as possible as well. 24 Software process modeling has been influenced by two major groups 29 : a group that model processes to understand and improve them and a group that model processes to automate them.…”

“…5 Henceforth, aside from helping the description of processes, models have to aid with automatic process execution. 27 Thus, the need for a new language that overcomes these problems becomes a necessity. After giving the context and the motivation of our work, we can now ask our research question as follows: Is it possible to have an easy to read and use SPML, which is abstract enough but also expressive enough to suit different domains of process modeling, and allowing the orchestration and execution of the process models it expressed?…”

“…The main constituents of most likely all process models are the created outcomes, the activities that create them, and the responsible roles. 27 As explained in Hachemi and Ahmed-Nacer, 42 "several works classified process models constituents" 43 and showed that the most important are: Task, Role, and Product. Consequently, we have opted for a metamodel based on three process elements (Task, Role, and Product) and seven process relations.…”

“…27 Using graphic notation makes work easier both for the reader and the creator of a process model, since it results in a more clear structure and a better comprehension. 27 The graphic notation "is absolutely useful in automated support, for process modeling or even for process execution." 27 POEML is a graphic language with the merit of being able to be read at a glance and to convey information regardless of a particular level of experience.…”
