Each of the 10 activities is estimated to take 8 days, with a 30% safety margin added by the estimators. This means each activity's duration with the safety margin is 8 days + (30% of 8 days) = 10.4 days. For 10 activities, this totals 104 days. The critical chain method involves removing these individual safety margins and adding a project buffer at the end. Without the individual safety margins, the total duration is 80 days (10 activities * 8 days each). If a project buffer less than the total of the individual buffers is added (which is common in critical chain project management to increase efficiency), the project deadline moves closer. The exact new deadline isn't specified, but it's clear that the project duration is reduced from the original 104 days, indicating a significant reduction in the project timeline.
