TLDR
This paper proposes to use an exception-handling mechanism to provide ‘transactional’ features for workflow management systems to provide transactional capabilities.Abstract:
Workflow Management Systems are becoming more and more important to organizations for the execution of business processes. However, most current systems lack a consistent way of dealing with failures and exceptions. This paper proposes to use an exception-handling mechanism to provide ‘transactional’ features for workflow management systems. The modeler specifies exception handlers for activities to deal with exceptions. These exception handlers change the workflow that is being executed to deal with exceptions as they arise. Based on this idea we discuss which exceptions and exception handlers should be supported and how they interact to provide transactional capabilities.read more

Specification and implementation of exceptions in workflow management systems
TL;DR: Chimera-Exc, a language for the specification of exceptions for workflows based on detached active rules, is presented and the architecture of a system that implements Chimera-Exc and integrates it with a commercial workflow management system and database server is described.

Workflow exception patterns
TL;DR: This paper presents a classification framework for workflow exception handling in the form of patterns that is independent of specific modelling approaches or technologies and provides an objective means of delineating the exception-handling capabilities of specific workflow systems.
Constraint-based workflow management systems : shifting control to users
TL;DR: This thesis proposes a new approach to workow management systems that can facilitate contemporary business processes in a better way by enabling a better balance between exibility and support.

Workflow exception patterns
TL;DR: In this article, a classification framework for workflow exception handling in the form of patterns is presented, which is independent of specific modelling approaches or technologies and as such provides an objective means of delineating the exception-handling capabilities of specific workflow systems.

Dynamic, Extensible and Context-Aware Exception Handling for Workflows
TL;DR: This paper presents the realisation, using a Service Oriented Architecture, of an approach for dynamic, flexible and extensible exception handling in workflows, based not on proprietary frameworks, but on accepted ideas of how people actually work.

Advanced transaction models in workflow contexts

TL;DR: It is shown that, in many aspects, workflow models are a superset of transaction models and have the added advantage of incorporating a variety of ideas that have so far remained outside the scope of traditional transaction processing.
