What are the types of poka yoke?
There are two types of poka-yoke: control and warning.
- Control: The goal is to make it mechanically impossible for mistakes to be made.
- Warning: Color or sound is used to alert operators that they are about to make a mistake.
What is poka yoke PDF?
Poka-yoke is a concept in total quality management which is related to restricting errors at source itself. It deals with “fool-proofing” or “mistake-proofing”. A poka-yoke is any idea generation or mechanism development in a total productive management process that helps operator to avoid (yokeru) mistakes (poka).
What are the three techniques 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 the lean manufacturing process?
The lean manufacturing process is a method for creating a more effective business by eliminating wasteful practices and improving efficiency. More widely referred to as “lean,” the lean process has principles that focus on improving products and services based on what customers want and value.
What are the 5 key principles of lean manufacturing?
Lean manufacturing has enabled businesses to increase production, reduce costs, improve quality, and increase profits by following five key principles: identify value, map the value stream, create flow, establish pull and seek perfection.
What are the 7 principles of development?

What are lean concepts?
Lean is the concept of efficient manufacturing/operations that grew out of the Toyota Production System in the middle of the 20th century. Lean is centered on preserving value with less work; with the ultimate goal of providing perfect value to the customer through a perfect value creation process that has zero waste.
What are lean skills?
Rooted in Purpose, Process and respect for People, lean is about providing the most value for the customer while minimising resources, time, energy and effort.
How do you calculate Six Sigma?
Once the number of products, defects, and opportunities are known, both DPMO and Sigma level can be calculated. Defects per million opportunities (DPMO) Six-Sigma is determined by evaluating the DPMO, Multiply the DPO by one million.
How do you find Sigma?
The symbol for Standard Deviation is σ (the Greek letter sigma)….Say what?
- Work out the Mean (the simple average of the numbers)
- Then for each number: subtract the Mean and square the result.
- Then work out the mean of those squared differences.
- Take the square root of that and we are done!
What elements are required for Six Sigma?
Which Elements Are Required To Calculate Sigma? (Points : 1) Number Of Defects And Standard Deviation. Process Performance And Customer Requirements. Cycle Time And Quality. Number Of Defects, Number Of Employees, Number Of Customers.
What are the three main components of the Six Sigma definition?
There are three key components of quality: Customer, Process, and Leadership. Everything we do to remain a world-class quality company focuses on these three essential elements.
How do you calculate CP?
Cp is an index used to assess the width of the process spread in comparison to the width of the specification. It is calculated by dividing the allowable spread by the actual spread.
What are the similarities and differences between lean manufacturing and Six Sigma?
Lean manufacturing is a systematic way of eliminating waste and creating flow in the production process, while Six Sigma is a set of techniques that strive to greatly reduce the rate of defects. Every business has areas that need improvement and sometimes it can be hard to know where to start.
What are the lean manufacturing and Six Sigma tools?
Tools for Lean and Six Sigma Lean: Kaizen (Continuous Improvement), Value Stream Mapping, 5S System, Kanban, Mistake proofing (Poka-yoke), Productive Maintenance, Set Up Time Reduction, Reduce Lot Sizes, Line Balancing, Schedule Leveling, Standardized work, and Visual Management.
What is the difference between Kaizen and Lean Six Sigma?
Kaizen tries to improve the business as a whole by creating a standard way of working, increasing efficiency and eliminating business waste. Six Sigma is more focused on quality output (the final product). Lean is all about eliminating waste to increase process speed and quality through the reduction of process waste.
