Abstract
For the last decades, management theories for public organizations (POs) have vigorously been studied and the number of practical cases is increasing. However, it seems that there is little literature on innovation management, especially on radical innovation for POs. Radical innovation requires POs to allow 'trial and error'. On the other hand, the bureaucracy system, which POs are basically adapted, never allows it. The purpose of this paper is to propose a new type of form that enables POs to solve the contradiction mentioned above.
