Industrial processes and manufacturing the concept of "7 wastes" refers to the types or non-value-adding activities that can occur. These are often associated with the Lean manufacturing philosophy, which aims to eliminate waste and optimize productivity. The 7 wastes, also known as "Muda" in Japanese, are as follows:

1. Overproduction: Producing more than what is required by the customer or producing too early. This can lead to excess inventory, increased costs, and wasted resources.over production is waste of time
2. Waiting: Idle time or delays between process steps due to inefficient workflow or lack of coordination. Waiting can lead to bottlenecks and decreased overall efficiency. It increase the waiting time for supplier.
3. Transportation: Unnecessary movement or transportation of materials or products. Excessive handling and transportation can increase the risk of damage and consume valuable time and resources.
4. Processing: Performing unnecessary or redundant steps in the production process that do not add value. Simplifying or streamlining processes can help reduce processing waste.
5. Inventory: Excess inventory beyond what is needed for immediate use. Excessive inventory ties up capital, occupies space, and can lead to obsolescence or waste due to spoilage. It increase the cost also for maintenance.
6. Motion: Unnecessary movement or motion of people within the workspace. Excessive walking, reaching, or bending can result in wasted time and physical strain on workers. Unwanted movement of person no use.
7. Defects: Production errors, defects, or rework caused by faulty processes or inadequate quality control. Defects result in wasted materials, time, and effort, and can lead to customer dissatisfaction.
