This next step in the Problem-Solving Process is the seventh step. It is important to understand what in the process allowed the problem to occur. A cause-and-effect diagram can be used to outline the reasons the problem occurred. By asking �Because?� the C&E diagram can be constructed.
Another effective tool is a process flow diagram. The process flow of the manufacturing or engineering process can be effective in identifying where in the process the problem could have been prevented. To prevent recurrence of the problem, most of the time a change to the management system will be required. Managers must understand why their system allowed a problem develop. The same system will allow future problems to occur.
