Abstract: Legacy systems have continued to pose a major challenge to digital transformation efforts in public administration. A comprehensive review of literature suggests seven levels of complexity in transforming legacy systems, including, being a stand-alone system, being part of a larger system, and data incompatibility, each depicting unique criteria and challenges. Nonetheless, very little is known as to what degree these complexities implicate the implementation of digital transformation efforts in public administration (PA). To address this gap, this research conducted an analysis on four cases of digital transformation in three European PA settings (i.e., Denmark, the Netherlands, and the UK). The findings revealed complexities that pose the key challenges to systems interoperability and integrability, which are crucial in any digital transformation project. In addition, a comprehensive understanding of the systems to be transformed, the policies which they are serving, and the broader PA setting in which they are implemented were deemed central to succeeding in digital transformation efforts.
