Help with a six sigma example
 

The below is from isixsigma.com. What I need help with is creating another similar example like the below, maybe a bit more complicated. Anyone? Thanks in advance.

As a simple example, picture a large block of very good Swiss cheese on a kitchen table a few feet away from an open screen door. The weather outside is warm. A man comes to the table for some wine and cheese and sees a mouse in the cheese.

Problem: There is a mouse in the cheese.

Solution: Throw out the cheese with the mouse and put a new block of cheese on the table.

That is not the Six Sigma way.

To do a root cause analysis of this situation, follow the DMAIC approach. The analysis might look like the graphic below.

Notice that solutions such as, "Be sure to close screen door," or "Put a note on door asking, 'Did you latch me?'" are not good solutions. They might work but they will not prevent the problem from recurring. A spring latch is a sure solution.

Re: Help with a six sigma example
 

The problem with Six Sigma is that cats are supposed to prevent mice from being in the cheese, and, as everyone knows, serve no other purpose. Therefore, the correct solution is to kill your cat.

Six Sigma missed this.
