520 Information science research frequently seeks to discover
the means by which practitioners can use information
technologies (IT) to accomplish their goals. From an
organizational perspective, the goal of IT is generally
presumed to be an increase in individual and/or
organizational performance. A successful implementation of
an information technology can therefore be thought of
simplistically as one in which the use of the new
technology improved performance. Prior research has shown
that one determinant of improved performance is how well
the functionality of an organization's information
technologies fits with the user's tasks. Theories relating
to IT acceptance, adoption and success suggest a positive
relationship between the task the user needs to accomplish
and the task the software was designed to accomplish, but
little has been done to explain how the IT artifact makes
design intent apparent to the user
520 This research examines a possible relationship between
design intent and fit: namely, how the designer's mental
model of an enterprise system's intended use influences
the design of the functionality and appearance of the
application's component features. Using a positivistic
case study methodology, mental models of intended use held
by seven teams of enterprise system software developers
were identified and classified. These models were then
related to the developers' statements about their specific
design decisions. The results confirm that developers'
mental models influence the design of software UI in ways
that are apparent to the end-user, and supports theories
that suggest that software has a "spirit" that consists in
part of an intended use. The research contributes to our
understanding of the source of that spirit, and identifies
specific ways in which software developers bias features
towards a specific type of use
