As a Quality Manager or Business Manager, you look at forced sorts as a sort of tax. One that you hate to pay and one that you want to get rid of as fast as you can. Unfortunately your sorting company has a different view of sorts. The longer the sort goes on, the more revenue and profit they make. Consequentially many companies trust their sort company about as much as they trust the IRS!
We've all heard the stories of a sort company salting a good batch with bad parts. While this is highly unethical and often hard to prove, it has happened. Even if your sort company doesn't operate in this manner, you may wonder if they are taking too much time for the sort or not supervising the inspectors to maximize production. This may create a rather antagonistic relationship between you and the sort company.
The solution is to develop a partnership with your sort company. If you don't think this is possible with your current provider, it's time to interview new providers. Find a provider that truly understands Quality and has as their mission to make your company stronger and more profitable, rather than just making profit for their company. This would be accomplished by having experienced sorters, good management, an expectation of explicit sorting criteria and the ability to relay detailed defect data on a daily basis.
When you are ready to look for a new provider, please add Continental to your short list of companies to interview.
