The paper sets out with considering increased decision interdependencies in the Transnational Organization due to autonomous IT deployment in national subsidiaries. It proceeds by proposing Multifactor Productivity as a controlling instrument for managing the increased level of decision interdependence in the area of IT deployment. It is demonstrated how Multifactor Productivity supports the twofold task of (1) capturing IT-induced decision interdependencies and (2) deriving IT policies to cope with them. Possible ways of using Multifactor Productivity are discussed as well a potential pitfalls in applying this concept. Finally, a proposal is made as to how this instrument could be implemented by IT Management in companies considering the transition to the Transnational Organization.
