Introduction Japanese manufacturing is known for its efficiency and pristine quality of products in practically every industry. Over the past decades, the country has developed and adopted various techniques in lean manufacturing and total quality management that the rest of the world has sought to implement. Poka-Yoke is considered one of the most valuable and highly standardized techniques which can be applied to any manufacturing or service industry. It is based on the principle of error prevention by ensuring proper conditions exist before each step of manufacturing is executed, identifying and eliminating potential defects early on in the process (Kanbanize, n.d.). Poka-Yoke essentially “fool-proofs” any mechanism or process, leading to the application of the principle in various items and devices that are used by consumers on a daily basis. This report will focus on introducing two devices that include an application of the Poke-Yoke mechanism. Total Quality Management As stated earlier, Poka-Yoke originated in Japanese manufacturing and revolutionized the process to the point of high efficiency with minimal errors. It allowed companies to develop an approach of continuous quality improvement that resulted in the production of high-quality goods without significant costs, consequently priced less on the market. This provides any company with a competent application of Poka-Yoke a significant competitive advantage. The principle essentially gave birth to the universally applied aspect of total quality management in a variety of given industries and sectors, ranging from engineering to medicine and finance. The Poka-Yoke technique is highly versatile and synergetic, allowing it to be combined with other quality management frameworks such as Six Sigma. Poka-Yoke provides the capability to enable companies to achieving objectives with zero defects (Vinod, Devadasan, Sunil, Thilak, & Murugesh, 2017). Figure 1 below demonstrates the mechanism of Poka-Yoke. Figure 1: Mechanism of Poka-Yoke in manufacturing (Concept Business Excellence, n.d.). Poka-Yoke is more than a manufacturing term but began to apply to services, techniques, and components of goods which improve quality and prevent errors. Handwashing techniques in hospitals, packaging for screws, and spell-check on word processing programs are prime examples of Poka-Yoke in the application, as they minimize human error by ensuring safety, comfort, or efficiency. Anecdotal evidence suggests that the implementation of Poka-Yoke in goods or digital services can be as much about being “idiot-proof” as preventing mistakes which may be dangerous, costly, or simply unnecessary, all with the help of relatively simple and innovative solutions (Schrage, 2010). With the modern consideration of a sustainable future, environmentally focused products, and socially conscious homes, devices and processes are becoming eco-friendly and many have features which are meant to prevent errors or waste that affect the environment.
