There may be other explanations for
this apparent paradox. For example, it has been noted that the task of searching through
a knowledge base using a KMS is often entrusted by senior employees to those who
are junior and may be less experienced [66]. It is difficult for such employees to accurately
judge the content quality even though they know the task and the context in
which the knowledge search is being done [13]. Thus, content quality may be silently
factored out of perceptions of usefulness. Other possibilities are (1) the abundance of
knowledge content in the available knowledge base makes it easy to locate the required
knowledge objects [18] and (2) the variety of knowledge objects makes it easier
to use all content which appears to be contextually useful [40].
