Which type of waste involves excess production of goods or services?

Overproduction is a type of waste that occurs when an organization produces more goods or services than are actually needed or demanded by customers. This can result in excess inventory, additional storage costs, and increased handling expenses. Overproduction often leads to other forms of waste as well, such as defects due to the rush to create more products, or wasted resources when products sit unsold.

In procurement and supply, managing overproduction is crucial because it ties up capital and resources that could be better utilized elsewhere. By accurately forecasting demand and aligning production levels accordingly, organizations can avoid the pitfalls associated with overproduction, such as increased costs and reduced efficiency in the supply chain.

The other options represent different types of waste. Defects refer to issues with the quality of goods, transportation waste relates to unnecessary movement of products or materials, and motion waste involves excess movement by employees, which can also lead to inefficiencies. However, none of these directly address the issue of producing more than what is necessary, making overproduction the correct choice in this context.
