Estimation of Activity Durations: Three-Point Estimating[1]

Three-point estimating is a tool used to estimate the duration of an activity. It is used primarily when there is insufficient historical data available to produce an estimate. The tool considers a most likely time (tM), optimistic time (tO) and pessimistic time (tP) to produce the best estimate via the following equation:

tE = (tM + tO + tP)/3

Using this triangular distribution estimation uncertainty and risk can be reduced with respect to single-point estimating.
