Generalized Process Structure Grammars for Flexible Representations of Work
Nathalie Glance, Daniele Pagani, Remo Pareschi
The promise of workflow solutions for coordinating organizational processes is currently being obscured by
strong criticism of the rigidity of their work representations. This rigidity arises in part from viewing work
processes as unfolding along a single line of temporally chained activities. In reality, work evolves both
horizontally, in the cooperation of causally unrelated, but information sharing tasks, and vertically, in the
coordination of causally-dependent activities. In this paper, we present our process modelling approach
which (1) views documents and tasks as duals of each other, capturing horizontal cooperation; and (2) exploits
constraints to express the soft dependencies among related activities and documents within the framework of
generative rule-based grammars for processes, thus handling vertical coordination.
