Delphi technique: a popular research methodology that straddles the divide between qualitative and quantitative methods

ABSTRACT

Conventionally the Delphi Technique is a research methodology that uses a series of questionnaires to generate expert opinions in an anonymous fashion to achieve a consensus over a series of iterations [rounds]. Due to multiple modifications of the technique its value as a research method is so controversial. However in essence it is a consensus building technique employed to help enhance effective decision making. Its use as a tool for solving problems in health care settings like in service planning, analysis of professional characteristics and competencies is well recognized with a variety of methodological interpretations and modifications
