The Gold Mine by Freddy Ballé, Michael Ballé Barnes Noble
"The Gold Mine" presents all the key lean principles, ranging from wellknown ideas such as pull and flow, to lesserknown yet equally important principles such as jidoka and heijunka. The book also reveals lean as a system—using a realistic story to show how the principles are interrelated and how they lead to useful tools such as kanban or 5S.
