Case National Emergency Supply Agency

Making the organisational foundation visible


The task of the National Emergency Supply Agency (NESA) is to safeguard Finland's energy supply and system functionality even in emergencies. The organisation deemed it necessary to carry out an enterprise architecture specification of its information systems so that the connections and interdependencies between functions, data, technologies and systems can be traced and designed. The project was kicked off due to Public Administration Recommendation JHS 179 (“Developing the ICT services: The enterprise architecture development”) and upcoming legislative amendments that NESA must comply with.

The project was implemented in cooperation with Digia's consultants. The consultants familiarised themselves with, for instance, the Act on the Measures Necessary to Secure Security of Supply, reference architectures and earlier descriptions of NESA's organisation, tasks, equipment and systems. NESA's recent information security guidebook also served as a key source of information. Interviews were also carried out and the results of other pending projects were utilised. The scope of the specification was primarily limited to the current state, with an emphasis on the description of system and technology architectures.


  • The specification compiles the descriptions of the current and desired states required for organisational development.
  • Enabling compliance with regulations concerning public administration.
  • The development of the organisation's operations and information systems will be on a robust foundation.
  • It will facilitate the future specification and design of information security.

Services and solutions:

Typically, enterprise architecture work is thought to be very extensive and slow. But it was a joy to work on this project. Cooperation has been smooth and pleasant all around.
