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

When multiple predecessor activities must all complete before a successor can begin, this is called a convergence point (or merge point). Activity F cannot start until both D AND E are complete — the most conservative constraint applies. Convergence points often increase schedule risk because F is delayed by whichever predecessor finishes latest.

**Why not B:** An external dependency involves factors outside the project's control, such as regulatory approvals or third-party deliveries. The scenario describes internal activities (D, E, and F) within the project's network, which is an internal logical relationship, not an external dependency.

**Why not C:** A loop would mean activities create a circular dependency, which is invalid in project scheduling. The scenario describes a linear convergence where D and E must both finish before F starts — there is no circular reference.

**Why not D:** A burst point occurs when one predecessor activity leads to multiple successors. The scenario describes the opposite — multiple predecessors (D and E) merging into one successor (F). This is convergence, not divergence.
