Anne Kristin Sortehaug Ajer of the Faculty Social Sciences has submitted her thesis “Institutional perspective on introducing enterprise architecture. The case of the Norwegian hospital sector”,and will defend the thesis for the PhD-degree Wednesday 10 June 2020.

She has followed the PhD-programme at the Faculty of Social Sciences with Specialisation in Information Sciences.

Summary of the thesis by Anne Kristin Sortehaug Ajer:

Challenges with large public ICT systems

Failed data projects in public sector have repeatedly characterized the news scene. What are the challenges when developing large common ICT systems?

Enterprise architecture (EA) is a method for developing and managing the ICT landscape in large organizations.

EA in the hospital-sector

The dissertation looks at the challenges of using EA in the public sector, with a special focus on the hospital sector.

To achieve national goals for holistic healthcare services, the idea is that the work processes should be the same, thus the associated ICT systems can also be the same. An important part of the picture is that the data must flow both between the different systems and between the different hospitals.

The findings show that the challenges associated with a holistic approach are strongly intertwined but have more to do with organization and people than with technology.

The various occupational groups such as managers, healthcare workers and IT specialists have different driving forces behind their work. This creates tensions when creating new systems.

Challenges and contradictions

Major challenges are related to the independence of organizations, national funding models and the lack of understanding of EA. It is also important that the characteristics of the EA and the healthcare sector are in contradiction.

An example is the long-term EA perspective compared to hospitals' need for ad hoc initiatives.

Standardisation of working methods is another example. It poses challenges in gaining acceptance and confidence that clinical knowledge is safeguarded and that support for local variations is provided.

Furthermore, views on privacy and protection of sensitive data may clash with the healthcare system's need for quick access to critical data.

EA-preparation needed

The dissertation shows that to succeed with the EA, the organization must be prepared for the EA and have interaction with the various professional groups.

Only then will the organizations benefit from the EA in its efforts to digitize the ICT landscape.
