Oliver Bossert and Jürgen Laartz (2015)
There is little agreement among companies about which management approaches are most effective; more empirical evidence is required. Most companies have a dedicated enterprise-architecture (EA) department that oversees the entire systems architecture, including business processes and IT infrastructure, and helps establish technology-enabled processes across business units so companies can deliver goods and services effectively. But not all companies agree on what constitutes best practice in EA management. Some are focused on continually measuring IT performance and adjusting business processes and systems as needed. Others tout the importance of aligning the overall IT architecture with those of the individual business units. And some companies say good governance can happen only if they have empowered EA leaders who promote collaboration and accountability among teams in IT and business functions. In our work with large global organizations and in our conversations with senior IT leaders across multiple industries, we’ve heard anecdotal evidence supporting all those beliefs and more. So which approach is right? What makes for world-class organization and governance of corporate IT systems?
