The process of Delphi method

PROCESS:

· The Delphi technique comprises several steps involving participants who may
or may not meet face to face.

· The participants (or panel) might be employees of a specific company
conducting a Delphi project or experts selected from the outside for their indepth
knowledge of a given academic discipline or manufacturing process.

ADVANTAGE:

There are several advantages to the Delphi technique.

· One of the most significant is its versatility. The technique can be used in a
wide range of environments, e.g., government planning, business and
industry predictions, volunteer group decisions.

· Another important advantage lies in the area of expenses.

· For example, the Delphi technique saves corporations money in travel
expenses.

· They do not have to gather participants from several points of the globe in one
place to resolve a problem or predict the future, yet they still can generate
relevant ideas from the people best suited to offer their expertise.

· This is particularly beneficial to multinational corporations, whose executives
and key personnel may be based in cities as far apart as Melbourne, New
York, Tokyo, Buenos Aires, and London.

· The technique also protects participants' anonymity. Thus, they feel better
protected from criticism over their proposed solutions and from the pitfalls of
"groupthink",
i.e., the withholding by group members of different views in order to appear in
agreement. On the other hand, the technique has its drawbacks.

DISADVANTAGE

· The Delphi technique is somewhat time consuming, which renders it
ineffective when fast answers are needed.

· It might also be deficient in the degree of fully thought-out resolutions. People
acting together in a group setting benefit from others' ideas. Thus, there might
be more insightful and pragmatic resolutions to problems offered by people in
interactive settings, e.g., through the nominal group technique,

· In which participants are gathered in one place but operate independently of
one another.

However, in situations where time is not of the essence or group interaction is not
important, these disadvantages diminish in importance.
