How to Use NGT for Risk Identification

I recently conducted an online survey to get feedback from project managers on risk management topics. One of the questions was, “What risk management techniques would you like to know more about?” One of the top responses was the Nominal Group Technique (NGT). Click here to see all the survey results.

Want to know about other risk identification tools and techniques? I shared 17 tools and techniques in my blog article What You Need to Know About Risk Identification.

What is the NGT?

The nominal group technique is an efficient means for identifying and ranking risks, as well as other items. It is brainstorming on steroids. Risks are collected from a project team. The risks are analyzed and ranked by the team.

The NGT is a powerful tool for larger groups.  The technique saves time, engages participants, and reduces groupthink — a phenomenon where people set aside their personal beliefs and adopt the opinion of a group.

How to Conduct NGT

The project manager asks the participants to identify risks in a category such as a schedule risks or budget risks.

The participants write down their ideas or items. Explain that there should be no discussions between participants.

The project manager asks each person for one idea from their personal list. The project manager captures items on a flip chart, white marker board, or cling sheets. Participants may “pass” if they have no remaining ideas. This step is complete when all ideas have been captured. Brainstorming rules apply.

NGT Example 1

Discuss all the risks to ensure everyone has a good understanding of the risks captured. Combine risks if they are similar.

Prioritize the list. I often use the 3-2-1 method. Participants rank the risks by assigning 3 points to the highest risk, 2 points to the second highest risk, and 1 point to the third highest.

The project manager might say, “Now I would like for you to write down the top three risks. Write down a value of 3 by the greatest risk. Write down a value of 2 by the second greatest risk. Write down a value of 1 by the third greatest risk.”

Collect and total the votes. Ask each participant for their votes. Total the votes. The items with the highest totals are the greatest risks.

NGT Example 2

In this example, our highest risks were Risk F with a score of 8, Risk C with a score of 5, and Risk A with a score of 4.

Discuss the results. Ask the participants if they feel the results are valid. Would they change the priority of any of the risks? Seek consensus.

The next time you need to identify and prioritize risks, consider the Nominal Group Technique. Contact me if you have any questions.

Questions: What other methods have you used to elicit and prioritize risks?
