# Characteristics Matrix - An example of a Completed Characteristics Matrix

Q

#### qualityworld1

Does anyone have an example of a completed characteristics matrix? I'm having trouble understanding what one is.

Thanks

well this matriX is only used by request of the customer, i have a 6 months trying to get some example but apparently nobody used it.

sorry i cant help...

The question is - is there a specfic format and content they want in a characteristics matrix? Many companies just point to the control plan. They're all there.

No one has ever requested from me a characteristic matrix.
As far as I understand it is for your help to enable you to see the interaction between different aspects of the control plan.

That's the same experience I've had, Howard.

Characteristic matrices are a tool that I have used in the past to determine the interrelationship of processes and inspection points in a process. The activity is pretty simple. Simply construct a table with all of the processes that a part will see across the top. On the left side of the table indicate all of the dimensions on print. At this point simply indicate at what operation the characteristic will be controlled or inspected. This is also a tool that will let you see if you are performing redundant inspection and where critical processing points lie. I do not have a form available to share.

#### first

what is the function of such martix?
such as we must finish the matirx, then we can do what,otherwise, we must wait until it is finished.that is its usage.

what is the input of the martix, in general?

is it revised?

is it relevant with Fmea or etc?

I hope get the further help. thanks

Typically a characteristics matrix is derived from characteristics on the print(s) and any process controls you identify in the process FMEA. Essentially it is a list of characteristics you plan to monitor / control.

Critical/Safety/(Important, etc. - whatever in accordance with your and your customer's terminology) characteristics are listed as a minimum.
