Step-by-step explanation:
The tool that a project manager might employ to determine the sources of an issue while controlling quality is the Pareto Diagram.
A Pareto Diagram is a bar graph that ranks issues or causes of problems in descending order of their frequency or impact. It helps to identify the most significant sources of issues so that the project manager can focus on addressing them first.
By analyzing the Pareto Diagram, the project manager can allocate resources effectively and make informed decisions on how to resolve the identified issues.
