Change Approval Requirements - Does every change need formal customer approval?

#1
Good morning!

Albeit checking in frequently for the very useful guidance and trove of expertise on this site, today my very first query. Indulge my naively start with a very general question and allow me to read through your first reactions before eventually switching to a more in depth discussion.

"Does every change need formal customer approval, or is it allowed/common to just inform the customer of implemented changes/upcoming changes?"

I think its going to depend on the requirements of the individual customer. We have customers that want change notification pushed up the supply chain as much as possible, with notification on any kind of change. These customers usually have a supplier agreement for us to sign which contains these notification requirements. Other customers only want notification if a component change would affect form/fit/function/price.

Dear Tagin,

Thanks for your reaction.
To your input, i see no issue in keeping our customers informed about changes, even beyond engineering topics. I believe our change management process is very solid and none of the changes we introduce are unplanned. Everything is consciously worked out and evaluated and tested prior to serial introduction. Even after full serial production we keep studying the effects of the change and move cautiously forward.
What bothers us somewhat is the expectation of a formal customer approval before any change can be introduced. I'm curious if there's actually a clear standard explaining when a notification is sufficient without having to go through the, often unwarranted time consuming, formal customer approval process.

What kind of changes are you referring to? If it's product changes, who owns the designs? Please be more specific.

Very much depends what is in your quality agreement with the customer. It is common to have three levels; customer approval required, customer notification required and no customer notification required. However where you draw the line between these is between you an the customer; and not all customers want the same thing.

There is no standard I am aware of. Instead, as has been mentioned, it is an agreement or understanding between you and your customer.

my two euros here...in the Automotive...now know as Mobility field....most have a requirement contained in their Source Package or Quality Manual (using generic names here as they vary from firm to firm) called a FR or Forever Requirement...some of these same firms have chosen to make this FR part of their Formal (Engineering) Change Notice or Change Request System...regardless of nomenclature, or location, the purpose is to capture changes that do not fall within the definition of their CN or CR system....in relative terms insignificant changes...The Point, its always best to solicit customer input and keep the lines of communication open...in my experience the great suppliers among other things do exactly this...this precludes any "unforeseen surprises" and is keeping with transparency.

Could you please be more specific in telling us more about your situation?

The Point, its always best to solicit customer input
Strongly disagree.
and keep the lines of communication open...
Strongly agree
in my experience the great suppliers among other things do exactly this...
In my experience, the great suppliers know from the above communication what the customers really care about, and know when it is in everyone's best interest NOT to solicit customer input because it will lead to a rabbit trail for all involved.
I've personally lost an automotive customer for sharing too much (a change to the product they buy).
I didn't lose it for the change...I lost them for being "too high maintenance" for informing them.

this precludes any "unforeseen surprises" and is keeping with transparency.
Completely agreed.

I parse the above only to point out that the boiler-plate statement "always ask" is not a good mantra.

Jim, as direct answers to some of your questions:
We produce a socket outlet with USB charging ports. we own the designs and development. Our OEM customers are buying a finished product on which we only adapt laser printing marking and colors of external visible parts according to their wish. The change we want to introduce is a shift form half automated to full automated injection moulding for one of the plastic parts.
I believe however, Correct me if I'm wrong, the answer to my question has been given: there's no international standard prescribing the change request/notification rules. It is a customer contract requirement and/or gentlemen's agreement based practice.
