Sheltered for a long time within the public sector environment with high job security and professional research autonomy, defense R&D organizations faced unprecedented challenges when government support was being withdrawn and closure threatening. They needed to be led by a suitable vision in order to implement comprehensive changes to their operations and remain viable. This study explores this constitution of vision as a mechanism of intentional change, a strategic tool to reach the desired future for the organization. Going beyond the current literature, the authors ask to what extent, and how, organizational members reconstruct vision in a way that it can support or detain change, a question of importance for management scholars as well as professional managers in both public and private organizations.
