The document discusses the three faces of Kaizen: fix leaks, make it flow, and create a new stream. It describes Kaizen as a process of first slowing down to fix issues and eliminate waste, then smoothing processes to remove impediments and reduce inputs. Once the process flows effectively, it is time to consider creating an new stream through uncontinuous changes or modifying product definitions. Throughout, it stresses the importance of never trying to accelerate and maintaining safety, effectiveness and quality.
