“…Flexible PAIS must be also able to cope with uncertainty. Common to existing approaches is the idea to defer decisions regarding the exact control-flow to runtime [13,17]. Instead of requiring a process model to be fully specified prior to execution, parts of the model can remain unspecified and be refined during run-time when more information is available.…”

“…Consequently, process flexibility has been identified as one of the fundamental needs for any PAIS and different enabling technologies have emerged [5][6][7][8]. They support adaptive processes [9][10][11], declarative models [7], late modeling [12,13], and data-driven processes [14,15]. Basically, we need to be able to deal with uncertainty, to cope with exceptions, and to evolve processes over time:…”

Abstract. Process-aware information systems (PAIS) must be able to deal with uncertainty, exceptional situations, and environmental changes. Needed business agility is often hindered by the lacking flexibility of existing PAIS. Once a process is implemented, its logic cannot be adapted or refined anymore. This often leads to rigid behavior or gaps between real-world processes and implemented ones. In response to this drawback, adaptive PAIS have emerged, which allow to dynamically adapt or evolve the structure of process models under execution. This paper deals with fundamental challenges related to structural process changes, discusses how existing approaches deal with them, and shows how the various problems have been exterminated in ADEPT2 change framework. We also survey existing approaches fostering flexible process support.

“…There are several approaches realizing these generic patterns. In [1], the notion of worklets, which are completely specified YAWL processes that refine a worklet enabled parent YAWL task at run time, is used for workflows in order to provide workflow run time flexibility. The selection of the most appropriate worklet for a worklet enabled task is based on rules considering context information.…”

“…For this purpose, placeholder activities are provided, which are modelled and executed during run-time. The guidelines or restrictions on the runtime adaptation are modelled as rules [1,8] or constraints [12]. On the other hand, there have been a number of constraint languages proposed in other disciplines, such as Object Constraint Language (OCL) [10] for object-oriented analysis and design method.…”

Abstract. In current dynamic business environment, it has been argued that certain characteristics of ad-hocism in business processes are desirable. Such business processes typically have a very large number of instances, where design decisions for each process instance may be made at runtime. In these cases, predictability and repetitiveness cannot be counted upon, as the complete process knowledge used to define the process model only becomes available at the time after a specific process instance has been instantiated. The basic premise is that for a class of business processes it is possible to specify a small number of essential constraints at design time, but allow for a large number of execution possibilities at runtime. The objective of this paper is to conceptualise a set of constraints for process adaptation at instance level. Based on a comprehensive modelling framework, business requirements can be transformed to a set of minimal constraints, and the support for specification of process constraints and techniques to ensure constraint quality are developed.Key words: Business Process Management, Process Variant Management, Constraint-Based BPM, Business Process Constraint Network Background and MotivationIn order to provide a balance between the opposing forces of control and flexibility, we have argued for [12], a modelling framework that allows part of the model that requires less or no flexibility for execution to be predefined, and part to contain loosely coupled process activities that warrant a high level of customization. When an instance of such a process is created, the process model is concretised by the domain expert at runtime. The loosely-coupled activities are given an execution plan according to instance-specific conditions, possibly some invariant process constraints, and their expertise.The foremost factor in designing business processes is achieving improvements in the business outcomes [4]. However, decisions at the strategic level
