Re: Deviation Format

Virender,

In order to better help, could you please provide more information as to what the deviation would pertain to. (e.g. contract, blueprint, customer specified requirement, etc.)

By the way welcome to the cove. :bigwave:

Re: Deviation Format

Hi, I need deviation format.
I note you've been around a few months, getting familiar with the Cove.

Your question is a good one and on a topic many people don't consider in advance.

Let me run a little "school" on deviations for folks who may not be familiar with the concept.

In a typical situation, suppliers enter into contracts with their eyes wide open and familiar with the kind of pitfalls that can happen during the process of making and delivering the requirements.

Sometimes, during the course of acquiring machines and materials, glitches occur. Often the glitch has to do with material: the customer requirements may have been for one grade or even brand of material, but for some reason it is unavailable or has become too costly. The supplier then requests a deviation (in advance) to substitute other material or increase the price to use the original material. [this is a deviation I am most familiar with]

Other requests for deviations may arise because a PPAP was perfomed on one machine or in one location, but force majeure has made it necessary for the supplier to use a different machine in the same location or an identical machine in a different location. This situation arose often during Hurricane Katrina and will be occurring now after the effects of midwestern flooding.

A third [and infrequent] request for deviation may occur because the supplier has found a "better way" which may result in better quality or lower price, but needs a deviation from the original contract or specifications to proceed.

It is important to note deviation is requested and granted BEFORE production. Compare this with "waiver" which is requested AFTER production because the completed product does not meet the contract specifications.

To my knowledge, occasions for deviations do not occur frequently enough for a "form," but certainly the "format" is relatively straightforward:

  1. State that the request is for a deviation from the original contract or specifications.
  2. List the details of the deviation sought.
  3. Explain WHY the deviation is sought - be very specific. If possible, list any advantage or benefit to the customer for granting the deviation (USUALLY a price concession or higher quality.)
  4. State that if deviation is not granted, supplier will declare force majeure to be excused from the contract if the situation is based on availability or price of the original material (there is never a good reason to subsidize the customer by losing money on a contract until AFTER trying to get a deviation.) Obviously, if the deviation was to change a process to benefit the customer, the supplier would be OK with sticking to the original contract if it isn't going to lose money.
Note some folks may interchange the terms deviation and waiver, but as long as a distinction is made whether the change from original requirements is BEFORE or AFTER production, everyone should be happy with either term. The difference, of course, is the supplier can get burned if the waiver [my definition] is not granted, whereas the supplier can get out with a relatively whole skin if the deviation [my definition] is not granted.

Thanks Frank for your response. I need This for the dimensions which are being accepted under deviation. The request should be from Production Department to Quality through Deviation Format to accept the material/component under deviation. I want to implement in my organization.

Thanks,
Virender Singh

Re: Deviation Format

I have attached an example of a form you can use as a guide. I hope this is of some help.
Nice form, but I think it's often important to be more specific about the duration or lifespan of the dispensation--does "one time" mean for this particular lot/shipment only, or for the current purchase order, including product that's been made but not shipped, or hasn't been made at all?

Also, the idea of a "permanent" deviation is usually used to avoid having to update drawings, which is almost never a good idea.

"One time" is usually for the current purchase order, that is the reason a field for entering the PO number was placed on the form.

Also, the idea of a "permanent" deviation is usually used to avoid having to update drawings, which is almost never a good idea.
I understand its never a good idea, but it happens. I have a deviation, on file, which states, "Use this deviation until we revise our prints". Mind you the prints haven't been changed since 2000.

Definitely having an idea of permanent deviation is not good. The deviation should be for specific quantity i.e. in WIP or Finished goods store. And the deviation should not make effect on customer specific requirement like fittment.

My understanding is a deviation or waiver is a temporary fix [until the condition requiring it is fixed OR the original requirement is formally changed.] In aerospace, "red line" drawings are ALWAYS considered temporary expediencies until an organization can process a formal change. (With aircraft, it is not unusual to have a separate formal requirement for EACH individual aircraft, not just the "type" [i.e. a type is a whole category: "747-300," "MD-80," etc.])
