Definition
A technique using optimistic, most likely, and pessimistic estimates to define an approximate range.
Three-point estimating in plain English
Guessing a drive will take "about an hour" is different from using last month's identical drive, or best/likely/worst traffic, or the longest chain of errands you can't skip. Three-point estimating is one of those estimating lenses — pick the wrong lens and your schedule lie becomes a surprise. Hold onto this precise job description: A technique using optimistic, most likely, and pessimistic estimates to define an approximate range. On a stem, name whether Three-point estimating is about timing, ownership, measurement, or delivery style — then eliminate the answer that borrows a cousin concept from the wrong phase.
