Factor analyses
Factor analysis of the organisational culture items yielded three factors that
were readily interpreted in terms of the original subscales, that measure a
bureaucratic, an innovative, and a supportive, organisational culture. Although
root-one criterion suggested that six factors could be extracted, an inspection of
the eigenvalue plot and using the scree test, suggested a three-factor solution.
The three-factor solution was adopted because of the interpretability of the
factors. All six items with their major loading on the first factor were derived
from the subscale measuring an innovative culture. The second factor was
most strongly defined by seven items derived from the bureaucratic culture
subscale, but with minor loadings from two other items derived from the
supportive and innovative culture subscales. The third factor was mainly
defined by items indicating a supportive culture. However, a single item from
the bureaucratic culture subscale (the organisation being perceived as
“power-oriented”) had a strong negative loading on this factor. Factor scores
derived from this analysis were therefore, labelled innovative culture,
bureaucratic culture and supportive culture.
