Which project management tool is a bar chart that shows the number and type of resources needed throughout a project?

• A. An organizational chart
• B. A resource schedule
• C. A resource histogram
• D. A staffing timetable

Answer: (C)

A resource histogram visualizes how many resources of each type are needed across the project timeline, using bars to represent quantities in each time period. This bar chart makes it easy to spot when demand peaks or dips and which resource types drive those peaks, which is exactly what a project manager needs for staffing and leveling resources. That’s why it’s the best fit here: it directly shows both the amount and the type of resources required over time, giving a clear view of loading and potential bottlenecks. Other terms describe different ideas. An organizational chart maps reporting relationships, not resource usage over time. A resource schedule conveys when resources are needed but isn’t inherently a bar chart showing loading. A staffing timetable isn’t a standard term in project management and doesn’t capture the graphical view of resource quantities across the schedule.
