All scale items were discussed with a focus group of eight executive MBA students
with an average of eight years of middle to upper managerial experience, who were
also familiar with KM and KM systems. Based on the feedback obtained, some questions
were rephrased and some dropped. Two constructs (Knowledge Content Quality
and Incentive) consisted of two scale items each—this is not uncommon, as there
are earlier research studies [12, 16, 37, 70, 82] that have used two scale constructs; for
example, extrinsic rewards [12] is a two-item construct, as is quality of information
[16]. A pilot study of 65 respondents from the same population provided further indication
of the appropriateness of the questions. Our final survey instrument is reproduced
in Tables 2, 3, and 4, which show the scale items along with the results of the
exploratory factor analysis as explained in the next section.
