What is an example of over processing?
Some prevalent examples of overprocessing include painting a car part which will never be seen by the customer or be susceptible to rust, or unnecessary plastic packaging on fresh fruit and vegetables.
What is over processing in lean?
Over-processing Over-processing refers to doing more work, adding more components, or having more steps in a product or service than what is required by the customer.
What is excessive processing?
Excess processing refers to the act of providing more value in a product than is required by the customer (Ohno, 1988). By providing more value than necessary, excess processing can cost organizations financial burden with respect to the materials used and the staff time required (El-Namrouty, 2013).
What is overproduction and over processing?
Overproduction: The act of producing more than is needed, before it is needed, and faster than is necessary. Overproduction is by far the most common type of waste in an organization, and it can breed other wastes. Overprocessing: This occurs when it is hard to see when something is complete.

What is the cause of overproduction?
Causes of Overproduction The desire for longer than necessary production runs or product batch sizes due to long setup times. Ordering more supplies than necessary, just in case. Expecting disrupted production flows. Unbalanced production stages, cells, or departments.
What are the 7 Mudas?
Under the lean manufacturing system, seven wastes are identified: overproduction, inventory, motion, defects, over-processing, waiting, and transport.
Why Overprocessing is a waste?
Overprocessing as one of the seven wastes is caused by having unclear standards and specifications, many operators will try to do the best job possible and will not always be aware of what truly adds value to the product or even the end use.
What are the 5 principles of lean thinking?
According to Womack and Jones, there are five key lean principles: value, value stream, flow, pull, and perfection.
Which waste is also called over-processing?
A simple example of overprocessing waste is when a part of a product is highly polished using labor and machinery when it’s not a customer or product functionality requirement.
What is an example of waste or Muda?
Waste of overproduction (largest waste) Waste of time on hand (waiting) Waste of transportation.
How do you control overproduction?
Then (second) addressing setup time is essential to reducing overproduction. By making setup times as short as possible, it becomes cost-effective to significantly reduce the size of production runs so that less overproduction is likely. Third you can implement a ‘pull’ system, or Kanban system to strictly control WiP.
What causes underproduction and overproduction?
When the government pays producers a subsidy, the quantity produced exceeds the efficient quantity. A deadweight loss arises than reduces total surplus to less than its maximum. Price regulations prevent price adjustments and lead to underproduction or overproduction.
How can over-processing waste be reduced?
Producing more detailed reports than necessary in order for one report to satisfy many users is one from of office overprocessing waste. Using Smart Factory Analytics with customized dashboards for each role can be one way to reduce excess processing waste.

How do you apply lean to improve a process you manage in your life or at work?
Here are a few examples of how to leverage the power of Lean in real life.
- Focus on Value. Lean doesn’t just dictate what companies do; it also tells them what not to do.
- Appreciate Incremental Improvement.
- Apply 5S.
- Use the 5 Whys Technique.
- Use Kanban.
- Minimize Waste.
How can we reduce over-processing?
How do you reduce lean overproduction?
In order to reduce overproduction waste that creates idle inventory, firms move away from ‘Just in Case’ manufacturing to ‘Just in Time’ manufacturing. This change smooths workflow and can dramatically decrease WiP (Work in Process) inventory investment.
What is overprocessing in lean manufacturing?
Overprocessing is one of the seven wastes of lean manufacturing (or 7 mudas); Overprocessing is adding more value to a product than the customer actually requires such as painting areas that will never be seen or be exposed to corrosion.
What are some examples of over processing in maintenance?
Examples of over processing in maintenance include unnecessary tasks and unnecessary assignment of staff to those tasks. Over processing is one of the largest contributors to wasted time and money.
What is an example of overprocessing?
This is classic overprocessing. An extra step that adds cost but no value. Note that this example not only adds cost to the vendor but cost and hassle to me, the consumer. I have to get rid of the silly things. They cling to everything. And are notorious for being environmentally unfriendly.
What is an example of over processing waste?
