In lean manufacturing, which waste refers to waiting time in a process?

In lean manufacturing, the waste that specifically refers to waiting time in a process is indeed delay waste. This type of waste occurs when there is idle time where no value is being added to the product, typically due to delays or interruptions in the workflow. It can arise from various factors, such as waiting for materials, equipment breakdowns, or slow decision-making processes.

Understanding delay waste is essential for improving efficiency in lean manufacturing, as reducing waiting times leads to a more streamlined operation where resources are utilized more effectively. The focus on minimizing delay waste aligns with lean principles, which aim to enhance productivity and reduce lead times by identifying and eliminating non-value-added steps in the production process. This ultimately contributes to quicker delivery times and improved overall operational efficiency.
