Those who are well acquainted with the tools and methodology of Lean manufacturing and lean know that most methods and tools use the principle of visual presentation of information. Until now, this topic has been touched upon only partially, in relation to the description of a particular method or tool. The book describes the mechanisms and rules of visualization using real examples, of which a sufficient number have accumulated over the years of practice. In the first part of the book, you will learn what distinguishes ordinary and non-working visualization from high-quality and effective one. You will become familiar with the rules for using visualization, as well as the areas of its application. The second part of the book is devoted to describing examples from various fields of activity, as well as examples related to the use of individual lean methods.
