Economies of recombination (ER) are seen as a way for firms to capitalize on previous knowledge creation, but the process that enables them to be accessed by firms is not clear in the literature. To date, temporary organization (TO) theory has focused on the process through the ‘transition’ concept via two units of analysis: within the project, and from a TO to a permanent organization (PO). Based on 67 interviews with inter-organizational project managers and four clusters, this research paper explores the factors influencing the transition process from one TO to another TO. Results identify eleven factors separated into three dimensions favoring or hampering this process: a structural dimension, which emerges from the first TO; the conjunctural dimension, which has a transversal effect throughout the transition; and the interstitial dimension, which is specifically highlighted between two TOs. We contribute to temporary organization theory by enlarging the scope of the transition concept and by identifying how clustered firms can jointly benefit from ER.
