Asset-driven workflow dependency management establishes connections between activities based on the descriptions of the assets used as inputs and/or outputs for each activity. These descriptive "contracts" provide a mechanism to readily match relevant activities necessary to create a desired output. By creating a graphical model of desired workflow a user is provided with a better understanding of what is involved in the workflow. The graphical model can be used to design and track real world productions. Graphical representations of activities are used to model venders, facilities and other production activities. The activity models produce and/or consume assets that represent the deliverables that are transferred between activities. Using the models of activities, a model of the production pipeline can be built from back to front. Thus, a final result activity model is selected first and based on the assets required by the selected final result activity an appropriate activity that produces that required asset can be selected. This process can be repeated until the beginning of a process pipeline is reached. A real world process pipeline can then be formed based on the model and the model can be used to track the status of the real world production pipeline. In order to prevent duplication and redundancy a workflow model can be created based on already existing assets. |
