What principle of Lean Manufacturing ensures that only good units move to the next process?

The principle of Lean Manufacturing that ensures only good units move to the next process is focused on maintaining high quality throughout the production line. This approach emphasizes the importance of quality control at each stage of the process, ensuring that only units that meet quality standards are passed along. This not only reduces waste caused by rework or defects but also increases overall efficiency, as time and resources are not spent on further processing faulty units.

Maintaining quality at each step is crucial because it helps streamline the flow of production and minimizes disruptions caused by defects. By implementing stringent quality checks, teams can identify issues early and resolve them before they impact subsequent processes. This ultimately contributes to a more effective and efficient manufacturing system, aligning perfectly with Lean principles that seek to eliminate waste in all forms.
