Voice of Business

  • Purpose of the tool

The Voice of Business serves to systematically identify the requirements of the internal business and translate them into measurable metrics.

It reflects the perspectives of internal departments such as Sales, Production, or Logistics and ensures that a project is relevant from the company’s perspective.

The Voice of Business thus serves as the central justification for a project. If there is no interest or no measurable pain point in the business, the project is not important to the company.

  • Example: Production and Sales

Rework (Voice from Production)
The production department reports high internal defect rates. These lead to increased rework costs, which are tracked as a measurable metric.

  • Business Voice: “Due to the many complaints, we always have to do rework.”

  • CBR: Current: €20,000/month; Target: < €5,000/month

  • Data type: Continuous

Delivery Performance (Voice from Sales)
Sales is criticizing insufficient delivery performance. This is represented by the OTIF (On Time In Full) metric.

  • Business Voice: “Our delivery performance is getting worse and worse.”

  • CBR: Current: 65%; Target: > 90%

  • Data type: Continuous

Loss of Revenue (Feedback from Sales)
Due to insufficient capacity and poor performance, customers are placing fewer orders. This leads to measurable revenue losses

  • Business Voice: “All the rework is costing us capacity—and revenue.”

  • CBR: Current: €2 million; Target: €2.5 million next year

  • Data type: Continuous
