3. Introduction
I 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!
