Abstract
This paper extends understanding about how middle managers work with performance indicators to strategize open innovation (OI) by taking a bottom-up perspective in the organization.•It draws on interviews carried out with eighteen (upper-level) middle managers from different global and internationally recognised organizations.•Through an abductive study, the paper compares how middle managers reason about their work with performance indicators to mobilise top managers towards an OI strategy.•Findings show that the situational nuances middle managers find themselves in, such as the extent of strategic support for an OI strategy by top managers and the degree to which OI practices are adopted, plays a critical role in influencing how they work with performance indicators.•The paper distinguishes different OI contexts and shows how those contexts affect the middle managers’ reasoning about their work with performance indicators. The different types of reasoning are labelled as abstaining, initiating, expanding, restructuring,and retaining.
