2. MURA, MURI, and MUDA MUDA – Waste MURA – Uneveness MURI - Overbudden

3. MUDA Any activity that doesn’t add value TIMWOOD (7 Waste) Transportation Inventory Motion Waiting Overproduction Over-processing Defects

4. Transportation Transportation is the wasted effort of moving materials or products that are not being worked on. In a manufacturing setting, this might refer to the unnecessary movement of components from one point to another. Keep in mind that materials and goods moved unnecessarily result in wasted time and money. Inventory Inventory refers to any materials or products that are not being used and are just taking up space. This might include raw materials, finished goods, or even  work-in-progress . Excess materials and goods take up space and money and can lead to confusion and mistakes. Motion Motion is the wasted effort of workers moving around unnecessarily, such as reaching, bending, stretching, walking, and lifting. This might be due to an inefficient layout of the workplace or poorly designed tools and equipment. Repetitive movements are also included in this type of waste as they do not serve any value to the customers or work productivity.

5. Waiting Waiting is the time spent waiting for materials, information, or approvals. This can lead to delays in the production process and result in decreased productivity. For example, employees wait for materials or instructions that never come, or they wait in line for machines that are not available. Overproduction Overproduction is the production of more than what is needed, either in terms of quantity or quality. This can lead to excess inventory and waste both time and resources. Producing more than is needed creates waste in the form of extra space in inventory and increased transportation needs.

6. Over-processing Over-processing refers to unnecessarily adding steps or components to a product or service than what is needed by the customer. Some examples include: using higher precision equipment when not necessary; running more analysis than needed; creating more reports than what is required; adding more steps to the purchasing process; adjusting a component after it has already been installed; or having more functionalities in a product than needed. Defects Defects happen when the product is unusable by the customers. Products that are not up to standard create waste in terms of time, materials, and money spent on reworking or discarding them.

7. MURA unevenness or irregularity, specifically in production levels. occurs because of wasteful allocations of materials or people. For example, employees might be directed to work intensely during the morning shift, which results in a lack of work to do in the afternoon. This start-speed up-stop scenario can be unhealthy for both workers and machines and can lead to unnecessary fatigue,stress , breakdowns, and accidents.

8. MURI The consistent overburden of equipment, facilities, and people. Muri pushes machines or people beyond their natural limits, causing fatigue and stress and increasing the likelihood of an accident. Overburdening equipment can also lead to breakdowns and increased defects, which results in wasted materials and products.

9. WORK STUDY

10. WORK STUDY The systematic examination of the method of carrying on activities so as to improve the effective use of resources and to set up standards of performance for the activities being carried out. METHOD STUDY Method study is a technique to REDUCE the work content mainly by eliminating unnecessary movements by workers, materials, or equipment. WORK MEASUREMENT Work measurement is the application of techniques designed to establish the time for a qualified worker to carry out a task at a defined rate of working.
