Voice of the Customer (VoC) is a fundamental concept in the journey toward manufacturing excellence. It represents the process of capturing, analyzing, and implementing customer feedback and requirements to improve products, services, and processes. In manufacturing, this approach ensures that the products not only meet but exceed customer expectations, which is crucial in a highly competitive market. VoC is a critical component in establishing a customer-centric culture, driving continuous improvement, and achieving long-term success in manufacturing.
