I thought that this picture is an excellent illustration of how different operational wastes are “Linked” together. The four key physical wastes in any operating business are “Process”, “Energy”, “Effluent”, and “Transactions”. These are not mutually exclusive. If you have process waste, i.e. inefficiencies in making your product, you are likely to be using more energy than you absolutely need, and creating unnecessary effluent in the form of defects or recycles.
Underpinning all this, will be a management process or transaction that is driving the others. This is is how they are all linked, and another justification for more simplification. If we look at the four electrical plugs we can see how these could represent the four wastes, and the totaliser above indicating that the whole is greater than the sum of the individual parts. We can use this as a means of showing our teams to challenge “Waste” as a means of reducing costs and driving a sustainable business. This “Lean Mindset” is the way we get staff to act as “Waste Hunters” rather than just Process Engineers and Statisticians.
