This paper reports on the continuation of a research that was started in 1994, when an attempt to implement a global information system in a large multi-national firm was investigated over the next 6 years. Already by 1999, however, it became clear that this, first, implementation was a resounding failure -but as a longitudinal, large scale case study it contributed richly to a wider study of the nature and specific character of such international information systems. In the last months of 2003 the firm, in a new structure, under new management, re-started the quest for global information systems support for its -now considerably more complex -international operations. The development, acquisition and implementation of the resulting suite of systems took the best part of 6 years again -but turned out to be an apparently successful project. This research, started in 2010, has two objectives: firstly to establish a comprehensive case history of the second project; and then to compare both cases to analyze differences and analogies in their respective approaches, contextual influences and structural underpinnings to validate and extend the previously established grounded theory.
