Task G is 6, task H is 0, task I is 4, and task J is 0. The 5 goes over to task D, plus 4 is an early finish of 9 for task D. I'll stop at this stop path and look at the bottom path next. "styles": { The Critical Path Method (CPM) provides a way for project managers to determine which tasks are critical (zero slack time) and which tasks can be delayed (and for how long).
