The field of Information Systems continues to change rapidly. The business landscape is being altered by rapid technology development, innovative business models, and a sustained business interest in digital transformation (Marr 2023). This offers an amazing terrain for researchers. We looked back at what was published 20 years ago in JSIS and compared it to current publications. The following pages provide two snapshots of JSIS content during these periods, as well as some reflections on the evolution of research published in JSIS.

This paper evaluates the dynamic aspects of the UML in the context of inter-organizational workflows. Two evaluation methodologies are used. The first one is ontological and is based on the BWW (Bunge-Wand-Weber) models. The second validation is based on prototyping and consists of the development of a workflow management system in the aerospace industry. Both convergent and divergent results are found from the two validations. Possible enhancements to the UML formalism are suggested from the convergent results. On the other hand, the divergent results suggest the need for a contextual specification in the BWW models.
