Enterprise Coherence Governance in the Public Sector -- Custodial Institutions Agency of the Dutch Ministry of Security and Justice

This paper is concerned with an application of the GEA (General Enterprise Architecting) method in the Dutch public sector, in particular at the Custodial Institutions Agency (Dienst Justitieële Inrichtingen, DJI), an agency of the Ministry of Security and Justice. The DJI is, on behalf of the Minister of Security and Justice, responsible for the enforcement of fines and custodial measures, following the decision imposed by a judge. The case study itself concerns the assessment of the impact of the introduction of a new law (the law on ´conditional realease´) on the DJI. The discussed DJI case is one of several cases that have been used to iteratively evaluate and improve the GEA method. This paper therefore also reports on the evaluation of the GEA method that was conducted after applying to the DJI case.
