The evolution of a network of collaborating software reuse
libraries implies the need for a common set of metrics relating to
user fulfilment. These libraries include domain-specific libraries
at several levels (project, department, enterprise) and non-domain
specific (or reference) libraries. A wide range of subject matter,
user communities, and library mechanisms are represented. Yet it is
highly desirable to seek a common set of metrics to be applied
across the board. Such a common set will necessarily be a "lowest
common denominator" and simplistic in nature. However, this
simplicity is advantageous because it enables one to easily gauge
how well each library is serving its users. It is general practice
to employ user surveys to provide this measure. It is obvious that
this may be perceived as highly intrusive to the user and it is
labor intensive for the library staff. Response rates are less than
100Therefore, it is desirable to have an alternative approach, such as
a preliminary assessment made by tracking the user's search and
retrieval path within the library mechanism without contacting the
user. The results of analyses to date at ASSET show promise for
this approach.
