In some theories, you can even find more types of Muda added to the initial seven. Every activity that is conducted in a business is either Value Add (VA) or Non Value Add (NVA). These necessary wastes should be identified and minimized, targets should be set for upper limit and tracked.

In other words, do whatever is necessary to arrange a process where workers need to do as little as possible to finish their job. The Japanese word for waste is muda (wastefulness, uselessness), which relates to muri (overload) and mura (imbalance). Based on his observations and deep analysis, he categorized the 7 types of waste (7 Mudas), which later became a popular practice for cost reduction and optimizing resources.
