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: | Three-point estimating is a tool used to estimate the duration of an activity.

Estimation of Activity Durations: Three-Point Estimating<reference name="PMBOK 6th Edition">https://app-knovel-com.proxy.findit.dtu.dk/web/view/khtml/show.v/rcid:kpGPMBKP02/cid:kt011DX7BB/viewerType:khtml//root_slug:6-project-schedule-management/url_slug:project-schedule-management?kpromoter=federation&b-toc-cid=kpGPMBKP02&b-toc-root-slug=&b-toc-url-slug=project-schedule-management&b-toc-title=Guide%20to%20the%20Project%20Management%20Body%20of%20Knowledge%20(PMBOK%C2%AE%20Guide)%20(6th%20Edition)&page=1&view=collapsed&zoom=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.
