What are the three technique of Poka Yoke?
Shigeo Shingo coined three types of poka-yokes: Contact method – identifies defects by testing product characteristics. Fixed-value – a specific number of movements every time. Sequence method – determines if procedure were followed.
What is poka yoke and give 5 example?
Poka-Yoke, also known as mistake-proofing, is a technique for avoiding simple human errors at work. Another example of Poka-Yoke device – many elevators are equipped with an electric eye to prevent doors from shutting on people. They are also equipped with sensors and alarms to prevent operation when overloaded.

What SMED lean?
SMED (Single-Minute Exchange of Dies) is a system for dramatically reducing the time it takes to complete equipment changeovers. The essence of the SMED system is to convert as many changeover steps as possible to “external” (performed while the equipment is running), and to simplify and streamline the remaining steps.
What is 5S Kaizen?
When looking to improve or change processes, the methodology of Kaizen will be much more helpful to managers and employees. 5S offers a series of steps a manager or employee can through to organize the space. These are 5 steps all beginning with ‘S’ and are: sort, straighten, shine, standardize, and sustain.
