Listen to What the Product Says
When a problem occurs or when our work encounters a roadblock, we must continue to examine the matter humbly and seriously.
For example, we may face a dead-end situation on our production floor where no matter what we do, our yield does not improve. At times like this, we must thoroughly and objectively examine every detail of our product, machinery, material, jigs and fixtures. We will then hear the cry of defective products and ill-maintained equipment. Our products themselves will give us clues to solving the problem.
We must humbly observe reality as it is, with no preconceptions or bias.
