The moderating role of internal and external resources on the performance effect of multitasking: Evidence from the R&D performance of surgeons

Abstract

R&D employees frequently must split their limited time between explorative R&D and exploitative operative tasks. This article explores the influence of this multitasking (pursuing both R&D and operations) on employee R&D performance. The article also analyzes how the relationship between multitasking and individual R&D performance interacts with the degree of access to internal and external resources. We hypothesize that multitasking positively affects R&D performance. Furthermore, we assume that the internal resources (funding, facilities, and support) are increasingly relevant when employees combine R&D and operative activities. However, multitasking employees may show less of a need for external resources (access to networks) in comparison to more focused colleagues. The results of a survey of 332 surgeons from 20 academic medical centers in Germany support our hypotheses. We conclude that managers should ensure that their R&D workforce is also involved in daily operations. Output will be optimized if these employees are not only engaged with explorative tasks but are also involved in exploitative activities. However, managers should also ensure that the appropriate organizational support is provided to individuals who attempt to combine exploration and exploitation. Multitasking individuals benefit the most from access to internal resources, whereas external resources are more efficiently allocated to explorative-only employees.
