This paper focuses on unsanctioned practice innovations (UPIs) and how they are generated realized by those outside the senior ranks of an organisation. Through a longitudinal in-depth qualitative study multinational firm between 2001 2014, we discovered deviance from formal procedural frameworks had diverse often creative productive effects that countered constraints transparency, legitimacy t...

A business process model represents the basic building block for a workflow-enabled enterprise information system. Generally, a process model evolves through numerous changes during its lifetime to meet dynamic and changing business requirements. It is essential that such changes are introduced systematically and their impact is clearly understood. Process model transformation is a suitable app...

Process modelling has a long and established research tradition, in the context of formally capturing sequences of activities, as well as the involved parties and the exchanged data. It will, without a doubt, continue to play a major role in the context of supporting the development of added-value services industry 4.0. In the medical domain, clinical pathways are a specific form of process mod...

With the increasing adoption of process-aware information systems, large process model repositories have emerged. Typically, the models in such repositories are re-aligned to real-world events and demands through adaptation on a day-to-day basis. This bears the risk of introducing model redundancies and of unnecessarily increasing model complexity. If no continuous investment is made in keeping...

In traditional real-time multiprocessor schedulability analysis it is required that all tasks are entirely serial. This implies that if a task is written in a parallel language such as occam, all parallelism in the task must be suppressed to enable schedulability analysis. Part of the reason for this restriction is the difficulty in analysing execution times of programs with a complex parallel ...

In process reviews, domain experts validate the model against reality. In general, reviews are conducted in an iterative manner. Better reviews can build consensus faster and save iterations, i.e. time and money. In an exploratory study, student clerks were asked to provide feedback to models from their domain. In this paper, we report on the study and the review performance. We explore typical...

Many organizations realize that increasing amounts of data (“Big Data”) need to be dealt with intelligently in order to compete with other organizations in terms of efficiency, speed and services. The goal is not to collect as much data as possible, but to turn event data into valuable insights that can be used to improve business processes. However, data-oriented analysis approaches fail to re...
