Creativity time is time “during which employees choose what projects to work on and how to complete such projects” (Burkus & Oster, 2012, p. 49). Creativity is critical to organizations’ competitive advantage but providing slack time for creativity and innovation is costly. In addition, the relationship between slack time and innovation is not straightforward. On the one hand, slack time has been linked to breakthrough innovation and experimentation as it allows organizations and individuals to allocate time to projects that may be riskier and that are not focused on short-term objectives. On the other hand, slack time has been associated with a reduction in discipline and selectiveness, leading to resource misallocation. This IRI research project aims to identify effective models for organizing slack time for innovation.
