Adaptive and Dynamic Service Composition in eFlow - Casati, Ilnicki, Jin.. (2000) (34 citations) (Correct)
....changes, by allowing simple modifications to the schema followed by a given instance as well as execution state modifications. Recently, some approaches to handle dynamic changes have been presented in the literature by the workflow research community. One of the first contributions come from [2], that defines a correctness criterion for instance migration, based on the definition of the set of all valid node sequences: a change is correct if the execution sequence could have been obtained with the new schema. The paper, however, introduces a simple workflow model and restricts to a ....

Rediscovering Workflow Models from Event-Based Data using .. - Weijters, van der Aalst (2001) (2 citations) (Correct)
....languages such BPEL4WS, BPML, XLANG, WSFL, WSCI, etc. have adopted most workflow concepts. Despite its promise, many problems are encountered when applying workflow technology. As indicated by many authors, workflow management systems are too restrictive and have problems dealing with change [2,4,7,12,20]. Many workshops and special issues of journals have been devoted to techniques to make workflow management more flexible (e.g. 2,4,20] Most of the research in this area is devoted to techniques to increase the flexibility either by allowing for ad hoc changes (as reflected by workflow ....
.... more flexible (e.g. 2,4,20] Most of the research in this area is devoted to techniques to increase the flexibility either by allowing for ad hoc changes (as reflected by workflow management systems such as InConcert [18] or by providing mechanisms to migrate cases and evolve workflows [7,12]. In this paper we take a different perspective with respect to the problems related to flexibility. We argue that many problems are resulting from a discrepancy between workflow design (i.e. the construction of predefined workflow models) and workflow enactment (the actual execution of ....

Such systems must be uniquely sensitive to a rapidly changing process execution triggered by collaborative decision points, context sensitive information updates, and other external events. The majority of current work addresses relevant issues at modeling and language levels [24, 36, 45, 53, 57, 70] while the relevant issues involving organizational changes appear in [24, 38] A particularly different approach to supporting adaptive workflow (capable of reacting to the changes in local rules and other conditions) has been developed using the notion of migrating workflows) 19] Related ....

Distributed Product Development in Virtual Communities - Schahram Dustdar Harald (2003) (Correct)
....work item is executed by a single worker. Hence, distributed collaborative work in virtual project communities finds almost no support by WfMS. Groupware [3, 6] on the other hand, typically does not contain any knowledge or representation of the goals or underlying business processes of the group [4, 5, 8, 10]. In this paper, we discuss distributed product development in a virtual project community provided by the MOTION teamwork services platform [11, 13] The contribution of this paper therefore is a scenario based discussion of process aware software engineering in distributed and mobile ....

Design for Change: Evolving Workflow Specifications in.. - Fent, Reiter, Freitag (2001) (Correct)
....control protocol. This protocol protects the retrieval of steps by workflows from updates of the steps by administrative transactions and controls which of the workflows can use an updated specification, and which has to stick to the old one. This way, it eliminates the dynamic change bug [9, 26], i.e. errors introduced by changing specifications of active workflows. ithin the transactions formed by the workflows each step can execute arbitrary actions (represented by dotted lines in the figure) on, e.g. an application database. Correctness of these actions with several workflows ....
....does not cause the WfMS to stop execution of running workflows, nor to delay starting new ones 4. The solution must be applicable within a system that isolates workflows with some kind of transactions and implements recovery by compensation [17] Requirements 1 and 2 are derived from [9], while number 3 is more than reasonable in a real life WfMS. Requirement 4 is mainly motivated by our specific setting, as ULTRAflow uses compensation for recovery, i.e. it performs semantically reverse actions to undo the e#ects of aborted transactions. In systems that do not rely on ....

....fully understand the concepts. At the moment, there are more than 200 workflow products commercially available [24] and many organisations are introducing workflow technology to support their business processes. It is widely recognised that workflow management systems should provide flexibility [7 9, 12, 16, 21, 28, 33, 36, 37, 47, 56]. However, today s workflow management systems have problems dealing with changes, e.g. new technology, new laws, and new market requirements may lead to (structural) modifications of the workflow process definition at hand. In addition, ad hoc changes may be necessary, e.g. because of ....
....(a) restart (b) proceed (c) transfer before change after = new process = old process Fig. 1. How to handle running cases do not affect running cases by allowing for multiple versions of the process, and (c) transfer: a case is transferred to the new process. The term dynamic change [21] is used to refer to the latter policy. Restarting cases causes no real difficulties except that it is often difficult to rollback the tasks that have already been executed. The proceed policy also causes hardly any problems. In fact, it is the only policy truly supported by today s commercial ....
