Q: How does the Project Plan 365 Scheduling Engine work?

The Project Plan 365 Scheduling engine works as described below: First Step: Create a graph where nodes are tasks and edges are precedence relations between tasks and do a topological sort to get the order in which we should process the tasks so we calculate early start and early finish dates. Second Step: Create another graph for successors of tasks and calculate the late start and the late finish dates so we can calculate the real start and finish date of tasks and slack and we can obtain the project duration , finish date and critical path with better accuracy. Third Step : Compute other task fields like cost , work and make sure that resource assignments are calculated correctly.
