IntroductionI try to understand Lean by

experiencing and seeing it in as many forms and situations as I can. This is an another attempt to do that. What

follows is a series of equations. Each equation addresses a lean concept or tool. Review them and see if they help you better see Lean, then create your

own. Enjoy!--Tom Curtis, 2010
