The purpose of this paper is to theoretically and empirically explore how organizations can enable radical product innovations to cumulate as stable designs. Radical product innovations are organizational responses to external triggers that cause transitions. To manage in transitions, it is necessary for radical product innovations to cumulate as stable designs. Organizations ability to co-evolve with the environment does influence innovations to cumulate as stable designs; to examine this, the author selected public procurement that uses IT as radical product innovation with pronounced environmental influence, government’s interventionist approach. The author used multiple case-study and obtained diverse analytic and heuristic views. From the cases, the author noted that actors did consider local and contingent factors only that resulted in certain radical innovations cumulating as stable designs. As an initial starting point, such actions are appropriate but organizational actions to expand their initial actions with a co-evolutionary framework that considers social contexts.
