Training alone does not effectively solve performance problems. Research shows that 75% of performance issues are due to contextual factors, not lack of skills or knowledge of individuals. Simply sending employees to training does not create real performance change. An effective approach analyzes performance data, identifies the root causes, implements interventions to address the system issues, and manages change through evaluation and measurement over time. This holistic human performance improvement approach can sustainably improve sales, customer satisfaction, project outcomes, and more.
