While some methods exist for measuring knowledge worker (KW) productivity, none are universally accepted. In general, most research suggests that the KW should be included in efforts to decide how to measure productivity as they have the best understanding of tasks they perform, relative importance, and potential metrics that assess performance. In addition, the most common challenge for rendering the KW productive is an appropriate handling of workload in general. In particular, the administrative workload, multitasking, and task switching have accounted for 20% to 40% loss in potential productivity. Therefore, keeping the KW focused on the tasks that matter most while ensuring that both the business and the KW understand what success looks like is paramount to strong business performance.
