Abstract: A critical date management system includes a critical date management module (CDM), project management system, and flow management system in which the CDM dynamically and automatically links activities and tasks in an overall project. Once a project plan is submitted to the CDM, the individual tasks are dynamically assembled together along with all dependencies and temporal data to create a complete end-to-end process flow containing all of the interdependent tasks. The assembled flow is then submitted to the flow management system for execution. The modular approach allows for the dynamic creation of a complete end-to-end delivery flow for different projects and project changes without the need for complex contingency logic. The result is a service delivery process that is customized for each new project. Additionally, when changes are made to an active project plan, manual recalculating of coordinated activities will be performed by the critical date management system.
