Abstract
Features that allow end users to make changes, adapt or tailor their
software applications have become increasingly common in the last
decade. Especially developers of generic, mass produced applications
seem to cram in tailoring features to make the systems flexible enough
for a wide variety of users. In this thesis, the use of these
tailoring features is studied in detail in an experiment including
eight end users. The results of the experiment are discussed to show
what aspects of the tailoring features are constraining or
facilitating to the different end users, and tell us that not all
features are accessible to all end users, because they vary in
complexity and difficulty. The process of tailoring is described using
concepts from the field of educational research.
