The Waste from Very Fat to Very Lean's Perspective - [Lean]

	Very Fat - Manager defines waste All what we spend time and resource on are needed, valuable and not waste. Nearly zero waste in out work.
	Fat - Oganization defines waste There may be some waste in our work, like the endless meetings. We admit 15% of our work is waste.
	Lean - Customer defines waste We generally treat what a *reasonable customer* doesn't want to pay for as waste. A reasonable customer understands why we spend time on testing and refactoring, and is willing to pay for it. Over documentation, unused features, efforts on defects and work in progress are all waste. There is always new waste identified from time to time.
	Very Lean - Critical customer defines waste We treat what a *critical customer* don't want to pay for as waste. Management, test, integration, refactoring and estimation are unfortunately on the list. They are *necessory waste* to prevent bigger waste. Doing them frequently, in small pieces, automaticly, early and with shared responsibility are pretty much the guidlines we rely on to minimize them. Sometime we cann't resist challenging everything and feel crazy, maybe we need a doctor at this time.
