Introduction:

Cause-and-Effect diagrams may be used to organize the causes identified for a problem. Select the most possible causes, and verify the cause-and-effect relationship between the most probable cause and the problem or effect under study. What action can be taken to resolve the problem under study. Typically, the many causes that can be associated with a problem are classified as machines, methods, material, people, and environment, and then further classified by sub-causes and sub-sub causes. However, these categories may be modified based on the type of problem under investigation. Causes are evaluated and verified by collecting data.

Let's say you are the branch manager of Al Inma Bank located at Riyadh Park Mall. You are facing a problem dealing with the long queues of people during operating in the weekends. Because this is a service operation, the classifications for possible causes of long queues can be management, staff, customers, process and possible other causes.
