Based on a survey of 83 instructional developers, this chapter considers whether the instructional developer/client relationship is a consulting relationship and, if so, whether consultants employ a specific consulting model. Four models of consultation are considered--the Product Model, the Prescription Model, the Collaborative/Process Model, and the Affiliative Model--and the phases and the task environment of the consulting process are detailed. The survey results showed that developers preferred the Collaborative/Process Model of consulting; however, a more systematic perspective of the consulting relationship based on leadership models is also presented. This model addresses the human and situational contingencies that affect the developer's decision to use a certain style or role with a client. Three tables are provided. (55 references) (Author/EW)
