A project manager identifies that a key resource is assigned to 150% capacity during weeks 5-8. What tool helps visualize this problem?

Show answer & explanation

Correct answer: Resource histogram

Explanation

A resource histogram displays resource utilization over time, making over-allocation immediately visible. When a resource's bar exceeds the 100% capacity line (shown for the assigned weeks), it signals over-allocation requiring resource leveling or crashing. The Gantt chart shows activity timing but not resource loading profiles.

**Why not A:** A network diagram shows the logical sequence and dependencies between activities but does not display resource allocation or utilization levels. It cannot visualize whether a specific resource is over-allocated during particular time periods.

**Why not B:** A Gantt chart shows activity timing, duration, and dependencies but does not inherently display resource loading or capacity utilization. While some Gantt chart tools can overlay resource information, the Gantt chart itself is not designed to visualize over-allocation.

**Why not D:** A milestone list identifies key project events and their target dates but contains no information about resource assignments or utilization. It is a summary-level schedule tool that cannot show resource capacity problems.
