TTNA Process Techniques

DOE-HDBK-1103-96

The TTNA process begins with a series of short introductions:

The coordinator introduces a manager from the operating organization that

needs the analysis, and

The coordinator introduces the facilitators.

The facilitators confirm the introductions with the coordinator and prepare a very

brief biography of their qualifications and experience for the coordinator's use

during the introductions.

4.6 TTNA Process Techniques. There are a variety of techniques that can be used while

facilitating the TTNA process. Each of these techniques are acceptable to use for each of

the steps of the process. The facilitator should become familiar with each of the

techniques in order to apply them when necessary. The decision about which technique

to use has to be made by the facilitator depending on the team cohesiveness, the desired

end product, available references, etc.

Nominal Group Technique/Consensus Decision-Making. Nominal Group

4.6.1

Technique (NGT) consists of each team member silently generating a written list

of ideas and then stating one idea at a time in a round-robin type format. A

round-robin involves each person taking a turn to state one suggestion from

his/her list. The facilitator will then write that idea on a flipchart. The next

person states a suggestion, with the facilitator adding the idea to the list, and so

on, until all persons have made one suggestion. The first person then states a

second suggestion from his/her list, etc. This process continues until all team

members have had an opportunity to exhaust their list.

When recording ideas during the round-robin on a flipchart page, ideas should be

alternated using two different-colored markers to make it easier for the team to

see each idea. Each item on the flipchart should be numbered to make it easier

when the team discusses certain items to gain consensus. During the round-

robin, it is important to record their ideas without judgment or discussion even

though revisions may occur.
