Abstract

A method for structuring the process of participatory document evaluation by a plurality of reviewers utilizing a feed-forward synchronization schema defined as a workflow graph (52) construct. The workflow graph construct allows one to define efficient document evaluation strategies that take advantage of the inherent parallelism within a business process, and take into account the data dependencies exhibited by the business process. Independent aspects of each document are evaluated in parallel, and a stage evaluation is started when all required data (including data provided by other reviewers) is available. The workflow graph construct assembles together a set of workflow objects (review (46), roles (48), stages (50), document (44)), and associates a set of functional properties to each of them. The topology of the workflow graph describes the synchronization schema, while the functional properties provide additional flexibility and further refine the evaluation strategy. A method for managing the process of participatory document evaluation by a plurality of reviewers utilizing a programmed computer system. Documents to be reviewed are prepared by a set of preparers, and are stored into a database (38). Reviewers participate in the review process by evaluating aspects of the document within their area of expertise. Depending on the information in each individual document, a set of reviewers is notified that the document is ready for their review. Each reviewer is notified at the time appropriate for his/her role via electronic mail by a workflow manager (30).
