Question

Identify a true statement about the poka-yoke concept.

Answer 1

The poka-yoke concept is a quality management technique that aims to prevent errors. It uses devices, procedures, or control measures to eliminate or detect mistakes before they occur. It is commonly used in manufacturing, healthcare, and service sectors.

Step-by-step explanation:

The poka-yoke concept is a quality management technique that aims to prevent mistakes or errors from occurring in a process or system. One true statement about the poka-yoke concept is that it helps to identify and eliminate potential sources of errors before they happen. This is done through the use of devices, procedures, or control measures that prevent or detect mistakes.

For example, a poka-yoke device may be used in a manufacturing process to ensure that the correct number of components are assembled in a product. If the number is incorrect, the device will not allow further assembly, thus preventing a potential error.

The poka-yoke concept is often used in industries such as manufacturing, healthcare, and service sectors to improve quality, reduce defects, and increase efficiency.

Answer 2

A true statement about the poka-yoke concept is that it is a quality control technique that aims to prevent errors or defects in a product or process.

Explanation:

The poka-yoke concept, also known as mistake-proofing, was developed by Japanese engineer Shigeo Shingo in the 1960s. It is based on the belief that human error is inevitable and can lead to costly mistakes, but these errors can be prevented through careful design and implementation of processes. Poka-yoke techniques can be applied to various industries, including manufacturing, healthcare, and service sectors.

One of the main principles of poka-yoke is to make the process foolproof, so that even someone with limited knowledge or experience can successfully carry out the task without making mistakes. This is achieved by incorporating simple and intuitive design features that prevent or detect errors before they can occur. These features can include physical devices, visual aids, or even sequencing of steps in a process.

For example, a common poka-yoke technique used in manufacturing is the use of sensors to detect if a part is missing before the next step of production. This ensures that the final product is complete and prevents costly rework or customer complaints. In the service industry, poka-yoke techniques can include checklists or forms that must be completed before proceeding to the next step, reducing the likelihood of errors.

In order to effectively implement poka-yoke, it is important to thoroughly analyze the process and identify potential error points. This requires a deep understanding of the process and the potential human errors that can occur. Through this analysis, appropriate poka-yoke techniques can be selected and implemented.

In conclusion, the poka-yoke concept is a valuable tool in quality control, as it helps to prevent errors and improve overall process efficiency. Its principles of simplicity, prevention, and continuous improvement make it a powerful technique for any organization looking to improve its processes and reduce errors. By incorporating poka-yoke into their operations, companies can save time, resources, and ultimately improve customer satisfaction.
