In this paper Professor Peter Hines revisits at the well-known five lean principles: value, value streams, flow, pull and perfection. While the principles proved highly remained robust in many ways, it may be time to take a fresh at these principles not least because our thinking has moved on since they were first proposed in Lean Thinking (1996). For example the environmental imperative is far more resonant for organisations today than it was then. At the same time, our understanding of the ‘people side of lean’ has taken shape with the benefit of hindsight.
Professor Hines suggests that we should now be thinking about our organisations in terms of the eight Ps: purpose; process; people; pull; prevention; partnering; planet; and, perfection. He goes onto examine each of the eight principles in turn. He proposed that one way to approach lean is through the development of a lean business system. This approach ensures that an holistic view of lean is taken which embraces each of the eight principles and avoids some of the pitfalls commonly encountered in lean implementation.
