Organizations are struggling to choose from or combine the different business process management paradigms offered in today's BPM landscape, such as workflow management, dynamic case management and straight through processing. The field of declarative processes seems to be able to address this challenge by offering a unified approach to business process modeling, providing variable amounts of flow at execution time and different levels of autonomy to the actors based on models using a single formalism. The notion of declarativity in business processes seems to be ill defined and is often treated as a black and white distinction. However, a number of quite different formalisms have been developed that are broadly agreed to be declarative. This paper proposes a number of qualitative characteristics to characterize the declarative nature of process modeling formalisms. The characteristics are evaluated by applying them to a number of relevant process modeling formalisms, both imperative and declarative, and we discuss how these characteristics can be utilized to create business processes that offer activity flows that are known up front where needed, and allow ad hoc approaches to offer experts freedom and to support impediment driven approaches in an STP context.
Managing and supporting the collaboration between different actors is key in any organizational context, whether of a hierarchical or a networked nature. In the networked context of ecosystems of service providers and other stakeholders, BPM is faced with different challenges than in a conventional hierarchical model, based on up front consolidation and consensus on the process flows used in collaboration. In networked ecosystems of potential business partners, designing collaboration upfront is not feasible. Coalitions are formed situationally, and sometimes even ad-hoc. This paper presents a number of challenges for conventional BPM in such environments, and explores how declarative process management technology could address them, indicating topics for further research.

Many organizations use business process management to manage and model their processes. Currently, flow-based process formalisms, such as BPMN, are considered the standard for modeling processes. However, recent literature describes several limitations of this type of formalism that can be solved by adopting a constraint-based formalism. To preserve economic investments in existing process models, transformation activities needed to be limited. This paper presents a methodical approach for performing the tedious parts of process model transformation. Executing the method results in correctly transformed process models and reduces the effort required for converting the process models.
