(Effort = 80 hours, Duration = 20 workdays, Elapsed time = 4 weeks) Summary Or if there are two workers committed to 10 hours per week each, the duration would be 20 workdays. (Effort = 80 hours, Duration = 5 workdays, Elapsed time = 1 week) However, if there are two workers each committed to 40 hours per week, the duration would be 5 workdays. (Effort = 80 hours, Duration = 10 workdays, Elapsed time = 2 weeks) If there is one worker committed to 40 hours per week, the duration would be 10 workdays. Installing the new drip system for the landscaping is estimated to take 80 hours of effort. Elapsed time does include holidays and non-working days. Elapsed TimeĮlapsed time is the calendar time or span required to complete the activities based on the resources available. Duration does not include holidays or non-working days and may be referred to work days or weeks. Durationĭuration is the total time to complete the activities based on the resources available to the project. In order to determine the activity duration, the effort required to complete the activity must be determined first. Effort may also be referred to as staff-hours, days, or weeks.
