A resource breakdown structure (RBS) is a hierarchical decomposition of resource categories and types, not a chart showing utilization or allocation over time.

It is the standard tool for identifying resource over-allocation or under-utilization across multiple projects in a program, making it the correct choice for the scenario described.

A Pareto chart is a quality management tool used to identify the most frequent causes of defects and has no direct relation to resource utilization tracking.
