This paper recognizes the important role played in the business community
by external management consultants and seeks to improve understanding of
how this role can be performed. Insight from the change management and
management consulting literature is used to further develop a general model
of planned change including the phases of entering, contracting, diagnosing,
leading, intervening and evaluating. Mixed methods blending a quantitative
survey and qualitative interviews were combined to provide the data for this
study. A quantitative survey was completed by a stratified sample of 198
company directors, chief executive officers, top managers, internal
consultants and line managers in relation to the practice of external
management consultants. Qualitative interviews with 16 leading figures in
the Australian business community provide further insight. There is useful
support for the model of planned change in the empirical results.
