The Research and Realization of a New Workflow Model with Step-Task Two Layers Based on Document

With the increasing in complexion of large-scale activities in business process, workflow model has been focused on highly than before. In this research, a new workflow model (WfM) with two layers (step and task layers) was proposed, which leads to process logic and concrete affairs couple loose, and deals with problems of simple logic of directed graph WfM and complex realization of net structure WfM. With the half structure model, process logic is defined during design, and real tasks route is chosen in practice, which enhances the flexibility of WfM. Besides, the notion, document-driven workflow, was introduced in that WfM. The parsing process of documents, the design format of documents and the delivery technology were also given. In order to accomplish a complete WfM, we integrated WfM and organization model in both static and dynamic ways. Finally we delineate the realization of S-T platform based on that WfM in this paper
