When Toyota was a small company, its goal was to sell inexpensive cars in Japan. Because it was small, it couldn’t use economies of scale to compete. Instead, they develop a series of techniques to eliminate waste and speed-up development time. These techniques eventually were called “Lean”, and later where incorporated in the Agile software development methodology.
The thing that really struck me about this book is it’s economy and logical style. Little fluff, very clear, well thought-out.
