The RecDel System is a low-cost software application that helps different groups of a complex project negotiate interfaces between interdependent schedules. The RecDel system is based on a concept of distributed planning, wherein the cognizant persons retain control over, and responsibility for, their own work; this contrasts with traditional centralized planning, in which responsibility and control are effectively transferred to central planners. RecDels are products, which flow between different areas of a project. The RecDel System makes it possible to identify product-specification and delivery-schedule disputes easily, solve problems quickly, eliminate schedule confusion, and verify receipt of deliveries. The RecDel System also supports action-item tracking as well as a limited earned-value capability. The outputs of the RecDel System include metric charts, Gantt charts, and a variety of text reports. Schedule reports can be generated at any time on any computer by any user for any level of the work breakdown structure. The RecDel System aids projects to effectively meet the demand for Faster, Better, Cheaper.
