Du, Weimin, Davis, Jim and Shan, Ming-Chien (1997): Flexible Specification of Workflow Compensation Scopes. In: Payne, Stephen C. and Prinz, Wolfgang (eds.) Proceedings of the International ACM SIGGROUP Conference on Supporting Group Work 1997 November 11-19, 1997, Phoenix, Arizona, USA. pp. 309-316. http://www.acm.org/pubs/articles/proceedings/cscw/266838/p309-du/p309-du.pdf

This paper addresses specification issues of workflow process compensation. The main consideration is to reduce the number of workflow activities that have to be compensated and re-executed when a failure occurs, as both can be very expensive. The main contribution of the paper is flexible compensation scoping strategies that allows process designers to specify compensation scopes in a simple way based on data dependencies between workflow activities. The specification helps the workflow engine to avoid unnecessary compensation at run time. The proposed techniques are simple to implement, but also have the potential of significantly reducing compensation overhead.
