This research shows how a multi-metric evaluation tool can provide deeper insights into participant feedback beyond a standalone Net Promoter Score analysis in B2B customer training at Baker Hughes. The dashboard was developed using a Design Science Research approach and integrates the Net Promoter Score (NPS) with eight predefined complementary metrics, structured around Kirkpatrick’s evaluation framework. Human-computer interaction (HCI) principles guided the design to support information retrieval, trend identification and interpretation of how participants perceived training sessions. Task-based usability testing with the dashboard showed strong results, with a task completion rate of 92% and a System Usability Score of 87.75%. The User Experience Questionnaire indicated positive user experience, although variation in pragmatic interpretation suggests areas for refinement. Secondary qualitative feedback confirmed the dashboard’s value and highlighted opportunities to improve interactivity and to integrate more qualitative insights. Overall, the realized dashboard provides a deeper understanding of training participant feedback by integrating multiple evaluation metrics with NPS through a design tailored to stakeholder needs at Baker Hughes. This enables well-informed, actionable decision-making that facilitates targeted improvements across the B2B training portfolio.
