Milestone

Definition

Milestone 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. Milestone is one of those estimating lenses — pick the wrong lens and your schedule lie becomes a surprise. Hold onto this precise job description: A significant point or event in a project, program, or portfolio. On a stem, name whether Milestone is about timing, ownership, measurement, or delivery style — then eliminate the answer that borrows a cousin concept from the wrong phase.
