Lean core idea is to maximize customer value while minimizing waste. Simply, lean means creating more value for customers with fewer resources. "More for less" Lean has a very extensive collection of tools and concepts. In this book we discussed the importance of these tools and our understanding of what they are and how they can help. This is an excellent way to get you started on your Lean Journey. We dedicated a chapter per tool; with a brief description and short explanation of how each tool can improve your business. If a tool captures your interest or resonates with you in some way; explore it further to decide if it is something to pursue now...or later. Many of these tools can be successfully used in isolation, which makes it much easier to get started. On the other hand, the benefits will compound as more tools are used, as they do support and reinforce each other.
