“The best ideas emerge when very different perspectives meet” – Frans Johansson
Introduction
Most successful people do not follow a linear path in life. They set big goals (and often achieve them) but they also aren’t afraid to change their minds and amend their goals.
Yes, if you believe in something, you should pursue it with all your heart and spirit. But if you find your interest waning, maybe it wasn’t the right goal in the first place. Or maybe you’ve just changed, and that’s fine. Life being short, you might as well spend your time working toward something you truly believe in.
Objective
The 4M (Man, Machine, Material, Method) change is an integral part of any organization or individual. Similarly, Rework and Repair is also an intrinsic part of any manufacturing process. Both Concession and Deviation Permit are inherent activities in any organization. The key objective is to understand their purpose and effectively implement it so that all the relevant stakeholders remained informed and it can be transparently accomplished.
Definitions (ISO 9000: 2015)
Concession (Cl 3.12.5): Permission to use or release a product or a service that does not conform to specified requirements
Deviation Permit (Cl 3.12.6): Permission to depart from the originally specified requirements of a product or a service before its realization
Detailed Information
| S.No. | Concession | Deviation Permit |
| 1 | Post-Realization | Pre-Realization |
| 2 | Unplanned | Planned |
| 3 | The intention is to conform to requirements but something went wrong. | Permission to make a product (or service) that does not comply with certain requirements, within certain limits |
| 4 | Shall also apply to nonconforming products and services detected after delivery of products, during or after the provision of services | Before the Event |
Commonality:
- Only an authorized person can approve a Concession/Deviation Permit
- Given for a limited quantity of product or period, and a specific use
- Maintain a record of the expiration date or quantity authorized under concession/deviation
- The organization shall also ensure compliance with the original or superseding specifications and requirements when the authorization expires.
- Material shipped under concession shall be properly identified on each shipping container (this applies equally to purchased product).
- The organization shall immediately notify the customer(s) if the nonconforming product has been shipped.
Present Challenges
- How often the deviation/concession is recorded officially and documented?
- How often FMEA is reviewed for any possible impact while approving deviation/concession?
- How often customer approval and communication with other relevant interested parties are conducted before deviation/concession?
