Poka Yoke Principles and Applications

The video tutorial introduces poka yokes, which are features in products or services designed to prevent defects or mistakes. It emphasizes the importance of preventing errors before they occur, as opposed to fixing them afterward. Examples include features in phones to prevent speaker damage, pizza ovens that ensure consistent cooking, and magnets in packaging plants to remove metal contaminants. The tutorial also explains three types of poka yokes: contact method, fixed value method, and motion step method. The video concludes with an invitation to explore further learning resources on Lean Six Sigma.

What is the primary purpose of Poka Yokes in products or services?

• To increase the cost of production

• To enhance the aesthetic appeal

• To prevent defects or mistakes

• To reduce the weight of the product

Which of the following is an example of a Poka Yoke in a phone?

• A feature that prevents the phone from overheating

• A feature that increases battery life

How does a pizza oven utilize Poka Yoke principles?

• By automatically cleaning itself

• By ensuring the oven is always on

• By operating only within a specific temperature range

• By changing its size based on the pizza

What is the role of magnets in a grain packaging plant as a Poka Yoke?

• To weigh the grain accurately

• To enhance the flavor of the grain

• To identify and remove metal pieces

• To increase the speed of packaging

Which method of Poka Yoke involves physical features that detect contact?

• Motion step method

• A fixed number of actions are performed

• The process is cost-effective

• The process is visually appealing

How does an online order form use the fixed value method?

• By providing discounts for complete forms

• By automatically filling in the address

• By requiring all information to be filled out before proceeding

• By allowing incomplete forms to be submitted

What is the purpose of the motion step method in Poka Yoke?

• To make the process more enjoyable
