This study sought to investigate the role of productive capacity in driving collective performance and, in so doing, provided initial empirical validation of Hausknecht and Holwerda‟s (2013) capacity-based perspective. Capacity emerged as generally predictive of performance, signaling, at least for now, its worthiness as a construct and the value of its associated measure. Additionally, the conceptual space of capacity was developed, with the construct positioned as a collective resource subject to contextual effects. While the evidence supporting contextual effects was meager, it was also promising as, under the right analytical conditions, an interaction between capacity and context emerged to predict performance.
