Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE credits
Most literature in Information Systems are good at pointing out the advantages of having
a well thought-out information infrastructure in place in order to support the activities of
the organization. They are also good at mentioning the problems that these information
infrastructures often have in reality. However, what the literature does not do too well
is to provide guidance as to how the integration of a new system into an already existing
information infrastructure can be planned and implemented.
As Hanseth and Lyytinen points out “a standard text book on object oriented method-ologies (Mathiassen et al., 2000) spends exactly 1% (4.5/450) of it’s pages on systems inte-gration and issues how to relate design to-be with the current environment” (Hanseth and
Lyytinen, 2004, footnote, p. 211).
This master thesis explores how a new information system can be integrated in the as-is
information infrastructure by analyzing the information infrastructure at Uppsala Univer-sity, where they have identified a need to address the existing problems. This is an informa-tion infrastructure that does not fully support the activities of the organization which leaves
them with a lot of unnecessary manual work that could instead have been automated. A
possible solution to these issues has been found to be the integration of a new system to fill
in the gap where the infrastructure does not support the organization. This is a complex op-eration and a complex issue which is also difficult to fully understand. Therefore this master
thesis explores and proposes a method where prototyping is used for multiple purposes to
elucidate and elicit both business and technical requirements concerning the integration of
a system into an existing information infrastructure.
50 user requirements, 5 interaction requirements and 5 information infrastructure re-quirements were generated through the use of the presented approach. The results suggests
that this approach indeed can be advantageous in situations where requirements concern-ing the new system as well as the interoperability with other systems in the information
infrastructure are not apparent and thus difficult to define.
