A cause-and-effect matrix can be used to evaluate and document relationships between input and output variables during root cause analysis.

It’s a great tool for prioritizing a long list of possible things you could do to improve a process  during your DMAIC project. After all, you can’t do everything so we should focus on doing the most important things!

It also can be used to prioritize key processes and input variables.

Hi Dan,

I found the link but it looks like the website was abandoned. Worse yet, the website that is now in its place is entirely infested with ID theft software.

So, I won’t post the link, but I can see what I can do about creating a download similar to what they show here. Is that what you were looking for?

Best, Ted.
