Waste is any step or action in a process that is not required to complete a process (called “Non Value-Adding”) successfully. When Waste is removed, only the steps that are required (called “Value-Adding”) to deliver a satisfactory product or service to the customer remain in the process.
The idea of process improvement is to identify and remove all forms of waste from a process in order to increase efficiency, reduce cost and provide customer value.
What are the 8 Wastes?
- Defects – Efforts caused by rework, scrap, and incorrect information.
- Overproduction – Production that is more than needed or before it is needed.
- Waiting – Wasted time waiting for the next step in a process.
- Non-Utilized Talent – Underutilizing people’s talents, skills, & knowledge.
- Transportation – Unnecessary movements of products & materials.
- Inventory – Excess products and materials not being processed.
- Motion – Unnecessary movements by people (e.g., walking).
- Extra Processing – More work or higher quality than is required by the customer.
To remember the 8 Wastes, you can use the acronym, “DOWNTIME.”
The 8 Wastes Observation Log is included in the The Problem-Solving Path™ Quick Win Project Planner. Use the 8 Wastes Observation Log to record any wastes you may observe during your Process Walk. Document the type of waste, the impact it has on your process and any clarifying notes.
