Abstract
Objective: To evaluate Use Case Maps (UCMs) as a technique for Requirements Engineering (RE)
in the development of information systems with functions for spatial analyses in
inter-organizational public health settings. Methods: In this study, Participatory Action
Research (PAR) is used to explore the UCM notation for requirements elicitation and to gather
the opinions of the users. The Delphi technique is used to reach consensus in the construction
of UCMs. Results: The results show that UCMs can provide a visualization of the system's
functionality and in combination with PAR provide a sound basis for gathering requirements in
inter-organizational settings. UCMs were found to represent a suitable level for describing
the organization and the dynamic flux of information including spatial resolution to all
stakeholders. Moreover, by using PAR, the voices of the users and their tacit knowledge is
intercepted. Further, UCMs are found useful in generating intuitive requirements by the
creation of use cases. Conclusions: With UCMs and PAR it is possible to study the effects of
design changes in the general information display and the spatial resolution in the same
context. Both requirements on the information system in general and the functions for spatial
analyses are possible to elicit when identifying the different responsibilities and the
demands on spatial resolution associated to the actions of each administrative unit. However,
the development process of UCM is not well documented and needs further investigation and
formulation of guidelines.
