So, what exactly is the meaning of the Delphi method?

The Delphi method is a decision-making process from a case or material, which is based on a collection of opinions from several experts in a particular field, without knowing each other among them.

Delphi Method Study Case

Surprisingly, it turns out that we often use this method in everyday life, here are examples of cases.

For example, you want to buy a new laptop, you definitely won't buy it right away right?

I'm sure you will consider in advance the specifications, features, models and prices. 

Are the specifications that you get are following the needs you expect.

Usually, while considering the decision, we often stop by some trusted YouTube channels that often review gadgets, such as Marques Brownlee, Unbox Therapy, Gadgetin, Sobathape, etc. 

You do that as a support for your decision to buy the product or not.

Well, indirectly we have used the Delphi method in our decision making at that time.

But the difference is, usually the analytical experts use the Delphi method by collecting data through questionnaires or surveys conducted to these experts.

Then the results of the answers from these experts will be floored into the forum and discussed to reach a final decision.

4 Stages of Delphi Method

During the analysis process, an analyst must pass 4 important stages in the Delphi method.

What are those?

1. Opinion Exploration

In the first stage, the analyst team will send several questions to expert resource persons.

The media and the number of questions are free, depending on the information needs of the analyst team.

2. Summarizing the Answers from the Experts

After the answers are collected, the analyst team will share the results of answers from other experts.

This has to be done so that the experts here can rethink their answers, whether they want to change them or stick with their previous opinion.

This is entirely the right of the experts.

3. Seek Other Information Sources
If There are Different Answers or Opinions

The analyst team will usually look for other sources of information if there is an answer that is felt ‘out of the box’

They must gather literacy and information from various sources so that they can find out why the expert gave very different answers from other experts.

4. Evaluation

This is the final stage of the team of analysts to decide on the opinion that the experts have given.

When to Use the Delphi Method

Then comes the next question, 

"When should we use this Delphi method?" 

Let's see the answer below.

1. Face-to-face Meeting is Not Possible

online meeting

This method is carried out if a group of experts who provide answers or solutions to a problem are not in the same city/country.

Jadi, hal ini tidak memungkinkan mereka untuk saling bertemu.

2. There is One Dominated Opinion

If there is a possibility of dominance or excessive power of opinion from experts. 

Example: You're looking to analyze the possibility of Liverpool winning. But the experts who give the opinion are Manchester United fans. 

The answer is going to be subjective right?

Therefore, you need this method to produce an objective answer.

3. No Historical Data

the Delphi method is used when there is no historical data

When the analyst team does not have historical data from a problem. In other words, the problems that arise are something completely new. 

So the use of the Delphi method is highly recommended.
