Operating on an early start schedule means that activities will start as soon as possible, without waiting for their predecessors to be completed. This will result in a shorter project duration but can also increase resource requirements.

Looking at the table, we can see that activities A, B, C, and D have a duration of 5 days each and are all on the critical path. Therefore, they will all start on day 0. Activity E can start on day 9 (the earliest date after activity D is completed) and has a duration of 4 days. Activity F can start on day 5 (after activity A is completed) and has a duration of 3 days.

If we operate on an early start schedule, activity F will start on day 0 along with activities A, B, C, and D. Therefore, day 19 (3 days after activity F is completed) will have the lowest resource requirements because only activities E and D will be in progress, and their total duration is only 9 days (4 + 5).

In contrast, day 15 will have higher resource requirements because activities A, B, C, and D will still be ongoing, and activity E will have just started. Day 24 and day 29 will have even higher resource requirements because all six activities will be in progress.
