IT Governance is a critical aspect to the success of IT performance in any organization and much has been written about the role of the CIO in this context. However, for many private and public organizations successful IT governance involves inter-organizational cooperation. For example, health care delivery depends of pharmacies cooperating with hospitals and governmental services can often rely on local governments sharing data.

In thinking about research and practice in this (inter-organizational) governance domain, please discuss:

1) Key research concepts or findings to consider when collaborating with other organizations to deliver an IT service to a customer or citizen;

2) From a practice point of view, what would be your priorities in designing an interganizational system in order to ensure: 1) an appropriate management structure and process (such as but not limited to a strategic architecture), and 2) adequate metrics to assess success.

What other important variables moderate the relationship between IT choices and strategic outcomes?
