Abstract: A method for developing and managing workflows is disclosed. The method enables the development of workflows from workflow templates and/or preprogrammed components; associating a workflow with a schedule; modeling a workflow as a plurality of tasks and a plurality of human-to-human or human-to-computer interaction points; and persistently storing the internal state of a workflow. The method employs computer-implemented forms to control the development, packaging, installation, deployment, enablement, association, instantiation, and termination of workflows.

Abstract: A workflow hosting collaborative application computing system is disclosed. The workflow hosting collaborative application computing system comprises a collaborative application able to support workflow services; workflow services supported by the collaborative application including a virtual workflow operating system and workflow management tools; one or more application programs for communicating with the collaborative application; and one or more workflow authoring tools for creating workflows. The workflow operating system includes a workflow engine for instantiating and executing instances of workflows created using the authoring tools. The workflow engine is preferably selected from a group of available workflow engines. The workflow engine includes a scheduler for scheduling workflow instance events to be executed by the workflow engine. The virtual workflow operating system also includes a base workflow host that performs transaction, messaging, notification, persistence and tracking functions.

Abstract: Workflows designed to take advantage of the capabilities of workflow-enabled application programs are disclosed. Examples of workflow-enabled application programs are word processing application programs and e-mail application programs. In response to determining that an incomplete workflow task exists, forms data is sent to a workflow-enabled application program. In response to the receipt of forms data, the workflow-enabled application program presents a workflow task form to the user of the workflow-enabled application program. Embodiments may determine whether a workflow task change or completion by a particular user at a particular time is authorized by the workflow. If a workflow task change or completion is not authorized the workflow rolls back the workflow task to a previous version of the task. Embodiments may determine if an incomplete workflow task is assigned to a group, and, if so assigned, function to prevent duplication of effort by participants in the group.
