The Voice of the Business (VOB) is a Lean and Six Sigma concept that focuses on the internal needs and priorities of an organisation. While the Voice of the Customer (VOC) highlights external expectations, VOB emphasises efficiency, cost management, and overall business objectives.
VOB emerged as a complement to VOC, recognising that organisations must balance customer satisfaction with internal sustainability. It represents the requirements of internal stakeholders—such as finance, operations, and management—ensuring that customer demands are met without undermining profitability or long-term business health.
Integrating VOB with VOC ensures a holistic view of organisational performance. It improves internal coordination, reduces costs, and enhances efficiency, while maintaining a strong customer focus. This balance supports sustainable growth, long-term competitiveness, and better risk management.
