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.

In APQP the significance of Characteristics Matrix for assembly type of industry what we need to prepare.

------------------

Could you further clarify your question?

ASD...

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.

The characteristic matrix (although not required) is a good tool to use as an input to the final control plan.

If used, the matrix should be part of the final APQP/PPAP evidence book.

In practical use, the control plan becomes a characteristic matrix.

Hi,
The characteristics Matrix, if done effectively can contribute to a lot of success in your Process review implementation.
Hey! Omnex does the best training program on these methodologies. I think they are present in India too. Visit their web site for more info.

Just a note: RonSmith is unregistered. I don't know exactly what the occasion is, but today every message Ron has left has been a confirmation of omnex. I wouldn't question this particularly, but with no registration it seems like a lot of love for omnex. I do hope this is not SPAM.

Hi Marc,
That aint no Spam.. Just thought I can share it with everyone, thats all!

Ron

If that's the case, no problem. You might want to provide some details in the future as to what specifically you use that Omnex sells and why you like it. Other details would also be appreciated.

When I see a sentence that just says something like "Hey! Omnex can solve your problems, they're the experts!" without any details of how or why you believe that and what program you use and what there is about it that you like, and then a link - well, to me that's 'approaching' SPAM, if not SPAM.

I would have said nothing if it was one message. Maybe even 2. But as I remember there were 6+ messages within a few minutes which all said the same thing - a sentence about Omnix and a link with no details. There was a 6th or 7th message which alone did not mention Omnix - you asked for a copy of a form from Al, as I remember, in one.

In addition, there was one response where you said something like "This is off topic, but whatever you need Omnix can help..." for which I could see no reason to be injected that into a thread. If Omnix can help, with some details tell us how they helped you.

Accolades are fine - but we're really looking for details that can help us evaluate possible choices and which help us as we make decisions rather than a blanket "...Company X is the best..." statement.

Lastly, this is not a slam against Omnix. They, like the other canned software solutions companies, make some canned solutions which work for some people in some companies.

Ron,

Join the forum , I'm sure you have some ideas and thoughts that could help us all.

Al...

Just to clarify, my comment that the poster was unregistered was only to say that there was no e-mail address so there was no way to even guess whether or not the post was legit.

That said, Al is right in that many companies do not have specific, discrete characteristics matrices. As far as going to Omnex for information as suggested by Ron, in fact you have all the information at hand right here at the Cove.

Characteristics matrices and other APQP requirements like this are discussed with some detail at All About the APQP Process (http://elsmarcom/APQP/). Be sure to read the notes below the slides.

Where iI can find example of characteristic matrix. Please tell me more information. :cool:

:confused: I WOULD LIKE TO KNOW CHARECTERICTIC MATRIX .BECAUSE AUDITOR WANT TO SEE CHARECTERICTIC MATRIX . I TRY TO SEE IN APQP MANUAL BUT CAN NOT UNDERSTAND ABOUT RELATION OF PROCESS AND INSPECTION POINT . SO I WOULD TO SEE EXAMPLE DETAILS OF CHARECTERICTIC MATRIX TO APPLY IN MY APQP DOCCUMENT (ISO/TS16949) .

Hi all
I have been working on the chareteristics matrix.
Below is an example

It sounds to me that it will be similar to houses of quality that are used in QFD exercises.

I have found an example.

See attached file. It gives an overview of which product characteristic is influenced in which process step.

Best regards,

Antoine
