Types of Product Disposition

 

 - Disposition is about arrangement so when the product is found to be non-conforming the decision has to be taken on the 'action of dealing with things in a particular way'

 - Disposition typically is defined, by most organizations, as an instruction that determines how a nonconforming material will be used.

 - Customer may expect you to apply the requirements of clause 8.5.2 and carry out corrective action including action to prevent recurrence of the nonconformity by eliminating the cause.

Types of Disposition

1. Segregation

 - Segregation means separate the Conforming and non-conforming products from the lot.

 - Segregation is not the disposition method but it is the process that you must perform when a lot of material fails to meet acceptance criteria.

 - If identifying non-conforming product requires an inspection method that is not typically performed, then the inspection plan needs to be corrected, or a corrective action plan is needed.

 - New and unforeseen defects may indicate a process change, a change in the raw materials, or inadequate training of personnel at your company or your supplier and it is recommended to consider documenting this investigation as an internal CAPA or a Supplier Corrective Action Request.

Example

 - Problem: After finishing the operation if we observed some variation in total length of product due to tool wear and tear.

 - Action: Segregate the conforming and non-conforming parts by using gauge or any other measuring instruments.

2. Rework

 - Rework means action taken on non-conforming product to make it conform as per requirement.

 - Rework takes additional time and therefore increases manufacturing cost of the final product.

Example

 - Problem: In the above example if the segregated parts having length variation in higher side and out of specification.

 - Action: We have to rework by re-machining process to correct the non-conformity.

3. Repair

 - Repair means action on non-conforming product to make it acceptable, i.e. product is not as per specification or drawing but after repair product is ready to use functionally.

 - Repair process has higher risk than rework.

Example

 - Problem: In the above example if the segregated parts having length variation in lower side and out of specification.

 - Action: We repair the parts by applying welding and then re-machining process to make the product functionally and specification wise ok.

4. Deviation

 - Deviation means anything that differs from the expected.

 - If the product is undersize / oversize we used that by taking under deviation approval from customer (Functionally only as size is already out of specification)

 - This deviation is temporary and apply to any defined requirement whether it be product or process related.

Example

 - Problem: In the above example some products observed out of specification which can't be rework / repair.

 - Action: We used that lot after taking under deviation approval from customer to reduce in-house COPQ. 

5. Scrap

 - The output of a production process that is not finished goods or WIP.

 - Scrap usually costs money and time.

 - Scrap is also defined as small amount of something, often left from something larger.

Example

 - Problem: In the above example some what if the customer decline the under deviation request?

 - Action: All the out of specification products are scrap.
