Teaching can be seen as a process. It consists of a sequence of steps or functions : such as discovering information to delivering of lecture. Lean thinking aims to eliminate waste from any process. Therefore teaching is good candidate for the application of principles of lean thinking. Teaching is moving teaching what to teaching where. In the past, when schools were less in number and teacher were difficult get, teacher's job consisted of teaching a student "what and how". With the spread of education and advent of web, number of resources that teach you " what or how" are increasing in number and accessible from anywhere.
