Quality at the source

Quality at the source means that each employee is held responsible for ensuring the quality of products. This is accomplished with the following tools:

  • Mistake proofing. Delve into the causes of poor quality and correct the underlying issues, so that they do not occur again.

  • Self checks. Allow workers to measure the specifications of their work, and call for help if units are out of spec.

  • Standardized work. Use a high level of documentation and training to ensure that each product is manufactured the same way, every time.

  • Successive checks. Each successive workstation checks the quality of the incoming work.

  • Visual management. Use a signaling system to pull engineers and managers to the spot where there is a problem, so that it can be corrected at once.
