WHAT IS WASTE?

Waste in processes are a major source of inefficiencies that prevent the process to run smoothly.

Waste is “Muda” in Japanese. Waste / Muda is a major topic in Lean methods.

When we eliminate the wastes, we only have the steps of the process that are necessary and we call them – value-adding activities, with these we aim to deliver better quality of the product or a better service for the end customer.

The eight types of waste are relevant to any process be it technical, operational, manufacturing or related to services
