On a library expansion schedule, ribbon-cutting on June 1 is listed beside 'pour foundation — 10 days.' How should those two items be distinguished?
Select an answer to reveal the explanation.
Short Explanation
A milestone is a flag in the ground—'we opened'—not the hours of digging that got you there. The ten-day pour is the work; ribbon-cutting is the celebration checkpoint.
Full Explanation
A milestone represents a significant point or event in the project and is typically modeled with zero duration. A task or activity represents work that consumes time and resources, such as a ten-day foundation pour. Mixing those concepts misstates progress and resource needs. CAPM schedule planning expects candidates to tell event markers apart from duration-bearing work.
