The Lean Voice of the Customer (LVOC) is a structured tool that translates the customer’s insights into actionable product requirements. It helps organizations distinguish between “qualifiers” (qualifying requirements to compete in a market) and “differentiators” (features that create real customer value and competitive advantage). The LVOC enables teams to focus on what truly drives customer decisions. The process emphasizes upfront cross-functional collaboration to align marketing, engineering, operations, and sales around a shared understanding of the customer needs. By applying Must/Should/Could prioritization, the team can balance cost, time, and risk while still meeting critical customer requirements. The outcome is a clear, validated Customer Requirement Specification that reduces waste, accelerates time to market, and increases the likelihood of product success.
Duration
Training is 2 days’ long depending on the product/market size and complexity. One full day is the minimum recommended duration to achieve any learning impact. Implementation workshop is recommended to last 2 days.
