However, in a strategic view, those critical factors are all significant
but not necessarily to implement at the same time. Even a same critical factor may be differently important to individual
firm with the varied priorities; due to each organization has its
own purposes, strategies, conditions of resources, and capabilities
in KM implementation. Especially, it is hard to obviate the possibility
of the causal relationship within those critical factors. If the
kind of causal relationship can be profoundly disclosed, the critical
factors are able to be well prioritized and segmented into some
meaningful groups. Hence firms can properly adjust the importance
of critical factors according to the strategic needs of different KM
phases. A list of critical factors is required to be further decomposed
for higher practical usefulness. To determine the importance of critical
factors is a qualitative decision-making problem and inevitably
involves the vagueness of human judgments [33].
