CAPM Practice: Demonstrate an understanding of a project management plan schedule

A lead allows a successor activity to start before its predecessor is complete. For example, in an FS relationship with a -5 day lead (sometimes written as a negative lag), the successor can start 5 days before the predecessor finishes. Leads accelerate the schedule by allowing overlap, while lags add delay between activities.

**Why not A:** This confuses the scheduling term "lead" with the organizational role of leading a team. In scheduling, "lead" is a specific technical term describing the acceleration of a successor activity relative to its predecessor, not the project manager's leadership role.

**Why not B:** The first activity in a project network is simply the starting activity or the project start milestone. It has no special designation as a "lead" in scheduling terminology.

**Why not C:** A delay added between activities to allow for drying or curing time describes a "lag," not a "lead." Lags add waiting time between activities, while leads accelerate successor activities by allowing them to start before their predecessor finishes. They are opposite concepts.
