Continuous Improvement, Lean Tools

Quality at the Source

I have seen it multiple times, there are problems in the production floor; a situation that happen very often and everybody is looking for a solution.  Very recently during a routine cycle count somebody read the label very carefully and realize the label did not match the product.  After verification of the product we found that the last three times we packed that product the wrong description was used on the label.  How it is possible that during four different production days the product had wrong information on the label and nobody picked up the problem.

Maybe we need to add an inspection point to verify the label, wait; we have quality inspectors coming once every hour to inspect some information of the label, not all of it.  Do we need more inspection? The question is, can the same person who changes the coder information, inspect the label right after choosing the new code?

Quality at the Source is a concept or tool where product quality is measured or inspected every step of the process.  If the operator of every step treats the next step operator as his/her customer, then they aim to deliver the customer the product they need, with the quality and quantity desired on time.  The use of specialized tools or technology help the operator to accomplish the quality expectations.  We can combine quality at the source with the use of Poka-yoke or “mistake-proofing” devices.

With employees participation the process of selecting the best process to ensure quality will be a good first step towards a problem solving and continuous improvement mentality.  After selection of the right process, training to all affected employees on who, when, where, what and how to perform the inspection is the second step.  Then we go to the plan execution and the subsequent analysis to determine if additional changes are necessary.  If no changes are necessary then the new process becomes the standard and quality at the source has been implemented.
