Abstract
Management consultants, like many other management advisory services, are based on a diffuse and heterogeneous knowledge base. Consequently, as illustrated in the previous chapter, the characteristics as well as the needs that MAS fulfill may vary between situations as the result of negotiations, primarily between buyers and suppliers of these services. Based on observed differences in the use of management consultants, including both the reasons why consultants were hired and the emerging consultant-client relationship, this chapter will investigate in more depth the organizational aspects that may help us to understand such differences.
