Poka yoke refers to a Japanese concept invented by Shigeo Shingo in the 1960s for Toyota as a means to prevent the company for making any errors. The word comes from “poka” meaning mistake, and “yokeru” meaning to avoid. The first term was actually called “baka-yoke” or fool-proofing, until it was formally changed later on when a worker was offended by its derogatory meaning.
The goal of poka yoke is to have zero defects and to prevent making any defective products. The concept is generally utilized in the manufacturing industry but it’s also applied in offices, hospitals, and other businesses that are vulnerable or have the potential to commit errors.
Poka yoke can be easily utilized in your business. It can be implemented with a variety of simple instruments like warning devices, notifications, paper, fixtures, and so on. They serve as preventive measures to prevent people and machines from conducting mistakes. These devices should be easy to install, provide instant prevention and feedback, can function independently, and can be used by everyone.
A poka yoke presentation would reveal that unlike conventional inspection techniques, the practice does not cause any delay in the manufacturing process. Since it falls under the lean manufacturing methodology, little time is needed to ensure each product is free from defects. Given its time-saving capability, It causes a business to be more productive.
Employees engaging in a poka yoke presentation and applying the concepts in their task encourage them to consistently solve problems and make quality products. Plus, It enforces employees to be effective workers, preventing errors and getting zero defects. What does this mean? The need or the rate for reworking and repairing products is drastically reduced. Having faulty products represent waste and errors that could’ve been easily avoided. The objective of this is to constantly satisfy the customer at a minimum cost and with no waste.
It’s a fact that it needs a lot of devices to be effectively implemented. The difference lies in the fact that compared to conventional inspection methods, the devices are significantly less costly. Zero defects at a fraction of the cost of conventional methods; what more can you ask for? Engage your workers in a poka yoke presentation and see the difference.
