What is defined as work that adds no value to the product or service from the customer's perspective?

The concept of work that adds no value to the product or service from the customer's perspective is defined as waste. In systems engineering and process management, waste refers to activities that consume resources without contributing to the final outcome that the customer values. This can include unnecessary steps in a workflow, excess motion, or any other action that does not directly enhance the product or service.

Identifying and eliminating waste is crucial for improving efficiency and productivity. The focus is on maximizing value delivery to the customer; anything that detracts from that is considered waste. This aligns with principles found in methodologies like Lean, which emphasize value stream mapping and continuous improvement to reduce waste and enhance overall effectiveness.

Understanding waste helps organizations streamline their processes, ensuring that all efforts are directed towards activities that directly benefit the customer, ultimately leading to higher satisfaction and better resource management.
