6.4.3.2 Resource Breakdown Structure
The resource breakdown structure is a hierarchical representation of resources by category and type.
Examples of resource categories include labor, material, equipment, and supplies. Resource types may include the skill level, grade level, or other information as appropriate to the project. The resource breakdown structure is useful for organizing and reporting project schedule data with resource utilization information.

Explanation:
Pareto diagrams, exist as a special form of vertical bar chart and are used to identify the vital few sources that are responsible for causing most of a problem's effects. The categories shown on the horizontal axis exist as a valid probability distribution that accounts for 100% of the possible observations. The relative frequencies of each specified cause listed on the horizontal axis decrease in magnitude until the default source named "other" accounts for any non specified causes. Typically, the Pareto diagram will be organized into categories that measure either frequencies or consequences.
Histograms, are a special form of bar chart and are used to describe the central tendency, dispersion, and shape of a statistical distribution. Unlike the control chart, the histogram does not consider the influence of time on the variation that exists within a distribution.
