What are the 5 main types of waste?

Key Takeaways

• The five main types of waste are overproduction, waiting, transportation, over-processing, and inventory.

• Overproduction occurs when more items are produced than can be sold.

• Waiting occurs when items are waiting to be processed, such as waiting for a machine to become available.

• Transportation occurs when items are moved unnecessarily or excessively.

• Over-processing occurs when items are processed more than is necessary.

• Inventory occurs when items are stored unnecessarily.

What are the 5 Main Types of Waste?

Overproduction

Overproduction is producing more items than can be sold. This can lead to a number of problems, including:

• Excess inventory: Overproduction can lead to an excess of inventory, which can tie up valuable resources and increase storage costs.

• Wasteful use of resources: Overproduction can also lead to a wasteful use of resources, such as materials, energy, and labor.

• Environmental degradation: Overproduction can also contribute to environmental degradation, as the production of excess items can release harmful pollutants into the environment.

Waiting

Waiting occurs when items are waiting to be processed, such as waiting for a machine to become available or for a process to be completed. This can lead to a number of problems, including:

• Delays: Waiting can lead to delays in production, which can cause missed deadlines and lost customers.

• Increased costs: Waiting can also increase costs, such as overtime pay for workers and storage costs for items that are waiting to be processed.

• Frustration: Waiting can also lead to frustration among workers and customers.

Transportation

Transportation occurs when items are moved unnecessarily or excessively. This can lead to a number of problems, including:

• Increased costs: Transportation can increase costs, such as fuel costs and shipping costs.

• Environmental degradation: Transportation can also contribute to environmental degradation, as the movement of goods can release harmful pollutants into the environment.

• Damage to items: Transportation can also damage items, which can lead to lost revenue and customer dissatisfaction.

Over-processing

Over-processing occurs when items are processed more than is necessary. This can lead to a number of problems, including:

• Increased costs: Over-processing can increase costs, such as labor costs and energy costs.

• Reduced quality: Over-processing can also reduce the quality of items, as the excessive processing can damage them.

• Increased lead times: Over-processing can also increase lead times, as the excessive processing can add time to the production process.

Inventory

Inventory occurs when items are stored unnecessarily. This can lead to a number of problems, including:

• Tied up capital: Inventory can tie up valuable capital, which could be used for other purposes.

• Storage costs: Inventory can also lead to increased storage costs, as the items will require space in a warehouse or other storage facility.

• Obsolescence: Inventory items can become obsolete, which can lead to lost revenue and increased waste.
