Who is the author of Toyota Production system methodology?
Taiichi Ohno and Eiji Toyoda, Japanese industrial engineers, developed the system between 1948 and 1975. Originally called “just-in-time production”, it builds on the approach created by the founder of Toyota, Sakichi Toyoda, his son Kiichiro Toyoda, and the engineer Taiichi Ohno.
What is the first step in the VSM?
The first step in value stream mapping is to create a current state map. This map can help identify waste such as delays, restrictions, inefficiencies, and excess inventories. These are then eliminated in the ideal state map, which gives the organization a working plan to achieve lean efficiency.
What is value according to Womack and Jones?
Value is what the customer wants and he will pay for. This requires a precise understanding of the specific needs of the customer. It is said that up to 95% of process activities are non – value adding.
Who is the father of quality?

if something is done right first time, it is done perfectly every time, and no time and money is wasted correcting errors caused by doing it too fast or without controlling quality.
Is quality really free?
Quality is viewed as an expense, a trade-off, something that you have to spend money on. But you can’t manage with goodness as your definition of quality. Quality is conformance to carefully thought-out requirements. So quality is free because it is already built-in.

Who coined the term company wide quality control?
W. Edwards Deming taught methods for statistical analysis and control of quality to Japanese engineers and executives. This can be considered the origin of TQM.
Where did Lean Six Sigma come from?
1980s-2000s The origins of Lean Six Sigma’s predecessor, Six Sigma, can be traced back to the Motorola company in the United States in 1986. Six Sigma was developed within Motorola to compete with the Kaizen (or lean manufacturing) business model in Japan.
Why it is called 6 Sigma?
The name Six Sigma is derived from the bell curve used in statistics where one Sigma represents one standard deviation away from the mean. The defect rate is said to be extremely low when the process exhibits Six Sigma’s, where three are above the mean and three below.
Why does Toyota use JIT?
Use of JIT within the Toyota Production System means that individual cars can be built to order and that every component has to fit perfectly first time because there are no alternatives available. It is therefore impossible to hide pre-existing manufacturing issues; they have to be addressed immediately.
What are the two pillars of the Toyota Production System?
The two pillars of the Toyota production system are just-in-time and automation with a human touch, or autonomation.
Does Toyota use batch production?
The Toyota Production System uses Heijunka to solve the former by assembling a mix of models within each batch, and ensuring that there is an inventory of product proportional to the variability in demand. … Just-In-Time delivery makes Heijunka possible. Read our full Toyota Production System glossary here.
