The first step in developing the AHP model is to come up
with a hierarchical structure of the problem. This classifies
the goal and all decision criteria and variables into three
major levels. The highest level of the hierarchy is the overall
goal, i.e. to select the best KM tool for KM in the SAAB
department. Level 2 represents the criteria and sub-criteria
used in selecting the KM tools. Level 3 contains the decision
alternatives that affect the ultimate selection of the KM
tools. Fig. 1 depicts the hierarchy of the AHP model for
evaluating the KM tools.
