Lean Thinking

The book in 3 sentences: Value is what the customer perceives it to be. Transparency between collaborating companies should be viewed as a rule, not a bonus. Eliminating waste of time, energy, and money within organizations is like cutting excess fat from a diet—it's important and essential for health. Favorite quotes: “Teams that engage in direct dialogue with customers always find ways to more accurately define value and often discover how to improve both the flow and pull of the product.” “How can performance be improved? Sweating it out and working longer hours is not the solution, but that’s what most will resort to until they learn how to work smarter.” “Most companies can immediately significantly increase their sales if they find a mechanism to rethink the value of their core products for their customers.”

A.C. Bradley, the great Shakespeare scholar, defined tragedy in a single word: waste. What emerges in *Hamlet* and *Romeo and Juliet* is simple — there was immense potential in them. We can learn a lot from Bradley's definition. First of all, he gets straight to the point — this is the first characteristic of someone who knows what they are talking about. And, of course, it provides fundamental insight into the nature of tragedy.

In Japanese, "waste" is "muda." Interestingly, muda carries a handful of business meanings. It refers to human activities that consume resources without creating meaningful value. Resources are spent on correcting mistakes that arise from large inventories. These accumulate when supply exceeds demand, waiting on unnecessary or redundant processing steps, while people wait for parts to finish their work.
