A core principle of lean methodologies centers on the removal of non-value-added activities and resources. It focuses on streamlining processes by identifying and eradicating anything that does not directly contribute to the creation of a product or service that a customer is willing to pay for. For instance, this can involve reducing unnecessary steps in a manufacturing process, minimizing inventory, or shortening lead times for service delivery.
This focus yields significant advantages. By minimizing inefficiencies, organizations can lower costs, improve quality, accelerate delivery times, and enhance customer satisfaction. Historically, these principles evolved from manufacturing practices, particularly the Toyota Production System, and have since been adapted and applied across a wide range of industries and sectors.
