In which stage of the Value Flow Analysis should “Customer satisfaction (%)” be monitored?

Customer satisfaction is an Outcome KPI because it measures the end result experienced by the customer, not the internal activity or resources used. Inputs are what you invest (budget, staffing), process KPIs describe how work is executed (cycle time, error rate), and outputs capture deliverables produced (orders delivered, requests resolved). Satisfaction reflects whether those outputs met customer expectations in quality, timeliness, and overall experience. It is also often used at organizational scorecard level, with departmental dashboards showing the operational drivers that influence it (response time, first-contact resolution, defect rate, on-time delivery). Measurement challenges include survey bias, response rate, timing (immediately after interaction vs periodic), and consistency of the rating scale. Proper activation includes setting a clear survey method, minimum sample sizes, segmentation rules, and a reporting cadence aligned with decision cycles. A common pitfall is using satisfaction without driver metrics—teams can see the score but can’t identify what to improve. Linking outcome KPIs to leading indicators makes performance management actionable.
