ABSTRACT

Task B can only be started once Task A is completed, and Task D can only be started once Task C is completed. Task C can be done more or less concurrently with Task B.

The ‘actual’ bars show that Task A took longer than expected, making the start of tasks B and C late. Tasks B and C appear to have been done in the allotted time, but Task D has not yet been started. It should have started at the beginning of week 3, but it will not be started until the end of that week.
