Activity duration estimates are quantitative assessments of the likely number of work periods that will be required to complete a schedule activity. Activity duration estimates include some indication of the range of possible results. For example:
• 2 weeks ± 2 days to indicate that the activity will take at least eight days and no more than twelve (assuming a five-day workweek).
• 15% probability of exceeding three weeks to indicate a high probability--85% percent— that the activity will take three weeks or less.
