H4: The greater the autonomy for strategy selection, the greater the effectiveness of IS planning for the sub-
sidiary.
Strategy implementation planning defines change management and action plans, the evaluation of ac- tion plans, and the definition of follow-up and control procedures. The final implementation of the selected
strategy in the previous phase may be the weakest link in the planning process. This is so because IS plans are too often not implemented [92–94].
Autonomy for strategy implementation planning would place the responsibility for change management and action plans on subsidiary managers who are more knowledgeable than parent managers about local lead- ership skills, training needs, and potential implemen- tation resistance. Such autonomy would also place re- sponsibility for the definition of follow-up and control procedures on subsidiary managers who would be more knowledgeable about the local forces possibly causing runaway projects that might eventually never be imple- mented. Thus, this knowledge would help subsidiary managers feel more confident about their ability to per- form this phase, and make them more committed to it. On the other hand, if parent managers deny autonomy for this phase, then local managers might feel less own- ership and less commitment to the success of the phase. Thus, in accordance with Theory Y, we hypothesize:
