Abstract. This paper presents the realisation, using a Service Oriented Architecture, of an approach for dynamic flexibility and evolution in workflows through the support of flexible work practices, based not on proprietary frameworks, but on accepted ideas of how people actually work. A set of principles have been derived from a sound theoretical base and applied to the development of worklets, an extensible repertoire of self-contained sub-processes aligned to each task, from which a dynamic runtime selection is made depending on the context of the particular work instance. 1

Abstract. This paper presents the realisation, using a Service Oriented Architecture, of an approach for dynamic, flexible and extensible excep-tion handling in workflows, based not on proprietary frameworks, but on accepted ideas of how people actually work. The resultant service im-plements a detailed taxonomy of workflow exception patterns to provide an extensible repertoire of self-contained exception-handling processes called exlets, which may be applied at the task, case or specification levels. When an exception occurs at runtime, an exlet is dynamically se-lected from the repertoire depending on the context of the exception and of the particular work instance. Both expected and unexpected excep-tions are catered for in real time, so that ‘manual handling ’ is avoided. 1

Abstract. Workflow Management Systems (WfMSs) are implemented to support the modelling, analysis and enactment of rigidly structured business processes. However, they typically have difficulty supporting unexpected or developmental change occurring in the work practices they model, and are unable to provide adequate support for exceptions, or deviations from the process model, even though such deviations are a common occurrence for almost all processes. These limitations mean a large subset of business practices do not easily translate to the inflexible modelling frameworks imposed by WfMSs, and so has inhibited their wider acceptance. Workflow modelling frameworks are usually based on software programming principles and proprietary formats, which may not be the most ideal base for the support of flexible work practices. A better approach may be to develop a WfMS based on accepted ideas of how people actually work. This paper derives a set of principles for work practice from a sound theoretical base called Activity Theory. These grounded principles are then applied to a set of criteria that a WfMS must meet if it is to provide adequate support for flexible work methods. Commercial workflow products, and some research trends, are discussed in relation to the criteria specified. 1

System (DWMS) is a system developed in Bibliotheca Alexandrina, the Library of Alexandria, to manage the whole process of digitization including its various phases, system users, files movement, archiving, and integration with the ILS and the library digital repository. The system supports workflow dynamic evolutions and deviation to allow for exception handling. It provides history tracking of actions and flexibility to simultaneously manage multiple projects with a diversity of materials. Moreover, it supports ingesting a job in the middle of the workflow and allows easy integration of tools used to perform functions of the workflow.

Workflow Management Systems (WfMSs) are implemented to support the modelling, analysis and enactment of rigidly structured business processes. However, they typically have difficulty supporting unexpected or developmental change occurring in the work practices they model, and are unable to provide adequate support for exceptions, or deviations from the process model, even though such deviations are a common occurrence for almost all processes. These limitations mean a large subset of business practices do not easily translate to the inflexible modelling frameworks imposed by WfMSs, and so has inhibited their wider acceptance. Workflow modelling frameworks are usually based on software programming principles and proprietary formats, which may not be the most ideal base for the support of flexible work practices. A better approach may be to develop a WfMS based on accepted ideas of how people actually work. This paper derives a set of principles for work practice from a sound theoretical base called "Activity Theory". These grounded principles are then applied to a set of criteria that a WfMS must meet if it is to provide adequate support for flexible work methods. Commercial workflow products, and some research trends, are discussed in relation to the criteria specified.
