Activity Duration Estimates
“Activity Duration Estimates” is an output for the process “Estimate Activity Durations”.
Activity duration estimates are quantitative assessments of the likely number of time periods that are required to complete an activity. Duration estimates do not include any lags. Activity duration”
estimates may include some indication of the range of possible results. For example: – 2 weeks ñ 2 days, which indicates that the activity will take at least eight days and not more than twelve
(assuming a five-day workweek); and – 15 % probability of exceeding three weeks, which indicates a high probability?85 %?that the activity will take three weeks or less.
“Activity Duration Estimates” is an input for the process “Develop Schedule”.
The activity duration estimates contain the quantitative assessments of the likely number of work periods that will be required to complete an activity that will be used to calculate the schedule.
“Activity Duration Estimates” is an input for the process “Identify risks”.
Activity duration estimate reviews are useful in identifying risks related to the time allowances for the activities or project as a whole, again with the width of the range of such estimates indicating the relative degree(s) of risk.
