What term best describes wasteful barriers when mapping value streams?

The term that best describes wasteful barriers when mapping value streams is non-value-adding activities. These activities are those that do not contribute directly to the creation of value for the customer and can impede the efficiency of the overall process. In value stream mapping, identifying non-value-adding activities is crucial because eliminating or minimizing them helps streamline processes, reduce waste, and improve the flow of value to the customer.

By explicitly focusing on non-value-adding activities, organizations can better optimize their workflows and enhance efficiency. This leads to a better understanding of the value stream and more effective resource allocation, ultimately maximizing customer satisfaction. Recognizing these barriers is fundamental to continuous improvement within the ITIL framework, which emphasizes value creation and delivery.
