Join Chris Croft for an in-depth discussion in this video Putting in and positioning the floating tasks, part of Learning Gantt Charts.
- Now once you've got the critical path drawn in,…you can put in all the floating tasks.…This bit is a bit more tricky, but the good news is,…that if you do make a mistake, it'll be on a floating task,…and they don't matter nearly as much as the critical tasks.…If a floating task takes longer, it probably…won't affect your overall project.…They key to successfully putting in the floating tasks…is first, to put in the vertical lines.…By this, I mean the two constraints…that every floating task has, when it can start,…and when must it be finished.…
These come from the arrows going into…and out of the floating task.…So, if tasks G, H, and J have to be done…before D, then put a vertical line down…from the start of D, so that we can see that fact clearly.…Similarly on my diagram, K must be done…before D, and L and M come after C.…Can you see that vertical line coming down…from the end of C?…And they have to be done before the start…of F, so there's another vertical line…at the start of F.…
Finally, N can be anytime after C is complete…
