Quality Control ExplainedBlogs
Quality Control is a large part of many companies workflow processes. With a growing number of industries requiring some sort of quality control compliance, it is compulsory that you understand the concept fully. Accreditations such as ISO9001 require companies to follow a set out guideline that consists heavily on quality control.
We have compiled together some key areas to consider:
Discrepancy. This refers to immediate details of the problem. It would quite often be the case that your customer would ring up and give you information as to why they have rejected the item. You are also able to document detail as to how many have been authorised for return, along with reject information such as reject types and responsible parties.
Credit/Billing. This refers to any financial implications as a result of the reject. From here you would raise credit notes.
Containment Action. Containment action is precisely what it says on the tin. It refers to information regarding how we are going to contain the problem and stop it from affecting other units.
Disposition. You have had parts sent back to you. What are you going to do with them? Examples would be correcting the item in the form of a rework, or possibly scrapping it as it is unusable. At this stage, you can also determine information such as failure types.
Root Cause Analysis. A common term used with quality control and root cause analysis is the 5 whys. This enables users to go into multiple levels of detail in order to find the original source of the problem.
Corrective-Preventive Action. So we have identified the problem, now how are we going to stop it from happening again? For example, this could be a problem with the original cutting program, and so a corrective action would be to correct the program used.
Follow Up. Again, pretty self explanatory. This refers to any follow ups you wish to carry out to ensure that the original issue no longer exists. At this stage you may come to the conclusion that the problem no longer exists, meaning no further action is required, or that the action you have taken has not eradicated the problem.
-Inspection. Setting inspection criteria is often required of companies that comply with certain industry standards. This can refer to checks such as tolerances on dimensions, or even visual checks to ensure items are as they should be. The frequency of your inspections can also vary, you may wish to check every item, or may be every 1 in 10.
Quality control can play a huge part to the success of manufacturing companies. If recorded correctly, it can help in terms saving time and money. Setting out a process can also aid you in achieving certain accreditations that can set your company apart from the rest.
