It is a method to work with a collection of people and involve them in decision making but does not depend on existing group processes. 3 0 obj When stakeholders like a(/some) quantitative output of the process. Determining a good sample size for a study is always an important issue. She records each idea on a flip chart using the words spoken by the participant. "The Nominal Group Technique is a Participatory, Planning Method In Adult Education", Ph.D. dissertation, Florida State University, Tallahassee. Varga-Atkins, T; McIsaac, J; Bunyan, N. & Fewtrell, R (2011) Using the nominal group technique with clickers to research student experiences of e-learning: a project report. The nominal group technique (NGT) is a method to elicit healthcare priorities. Although, in the context of this study, the NGT discussions did not substantially affect the patients’ rank order of preferences for the attributes when compared with rank order before the group discussion, our approach is rigorous, transparent, and improves the face validity of future DCEs. [10], As compared to interacting groups the NGT groups provide more unique ideas, more balanced participation between group members, increased feelings of accomplishment, and greater satisfaction with idea quality and group efficiency.[11]. When some group members are much more vocal than others. If not, the problem is said to be ill-structured, and the ideas generated are clustered into coherent groups. nominal group technique (NGT) is a highly controlled small group process for the generation of ideas. Everyone must feel comfortable with the amount of structure involved. When some group members think better in silence. Liverpool: University of Liverpool. So we will need to sample at least 186 (rounded up) randomly selected households. "Expressed Satisfaction with the Nominal Group Technique Among Change Agents", "Applying the Nominal Group Technique (NGT) in Community Based Action Research for Health Promotion and Disease Prevention", https://en.wikipedia.org/w/index.php?title=Nominal_group_technique&oldid=993510015, Articles with unsourced statements from April 2020, Articles with dead external links from February 2018, Articles with permanently dead external links, Creative Commons Attribution-ShareAlike License. Silent generation of ideas: The Facilitator provides each participant with a sheet of paper with the question to be addressed and ask them to write down all ideas that come to mind when considering the question. 1 0 obj • The nominal group technique is more structured than the traditional focus group approach. [1] It can be used in groups of many sizes, who want to make their decision quickly, as by a vote, but want everyone's opinions taken into account (as opposed to traditional voting, where only the largest group is considered). Taking cue from the technique, Tunde Varga-Atkins, Jaye McIsaac and Ian Willis, [9] found that a two-stage combination of focus group and the nominal group technique, coined as nominal focus group, was particularly effective as an evaluation method. Voting and ranking: This involves prioritizing the recorded ideas in relation to the original question. Requiring individuals to write down their ideas silently and independently prior to a group discussion increased the number of solutions generated by groups. It is important to remember that no right or wrong method of prioritization exists. [2] The method of tallying is the difference. This process ensures all participants get an opportunity to make an equal contribution and provides a written record of all ideas generated by the group. Prioritization Matrix Each sub-section includes step-by-step instructions on implementation followed by examples illustrating practical application. So we will need to sample at least 186 (rounded up) randomly selected households. After all, using the wrong sample size can doom your study from the start. The round robin process continues until all ideas have been presented. 1. When there is a power-imbalance between facilitator and participants or participants: the structure of the NGT session can balance these out. Some potential applications of the technique in audit and exploratory research are also outlined. First, you need to understand the difference between a population and a sample, and identify the target population of your research.. Example. One major advantage of NGT is that it avoids two problems caused by group interaction. Specific sampling techniques are used for specific research problems because one technique may not be appropriate for all problems. It may also, in many cases be a time-saving technique. There is no spontaneity involved with this method. 4 0 obj the Nominal Group Technique No. This diversity often allows the creation of a hybrid idea (combining parts of two or more ideas), often found to be even better than those ideas being initially considered. NGT overcomes these problems (e.g.[13]). calculate the sample sizes in Tables 2 and 3 and is shown below. The population is the entire group that you want to draw conclusions about. Stratified Sampling. NGT has been described as a highly structured technique used to explore areas of interest and develop consensus. %���� This is a simple process that involves counting the number of votes for each idea and attributing points accordingly. First, every member of the group gives their view of the solution, with a short explanation. Typical applications of the techniques are for the development of consensus guidelines or standards in areas where research based evidence is absent or inconclusive. Nominal group technique. First, some members are reluctant to suggest ideas because they are concerned about being criticized, or are reticent and shy. The Nominal Group Technique was originally developed by Delbecq and VandeVen as an alternative to brainstorming. Defining the Nominal Group Technique Nominal (meaning in name only) group technique (NGT) is a structured variation of a small-group discussion to Brainstorming vs Nominal Group Technique. Background and theory 2. Statisticians attempt for the samples to represent the population in question. storming, nominal group technique and the ‘Delphi’ ... sample size, the greater the generation of data, which in turn influences the amount of data analysis to be under-taken. 4) A written record increases the group’s ability to deal with a large number of ideas. Written for the ELESIG Small Grants Scheme. which found that, in response to three different problems requiring creative thinking, the number of ideas produced by "nominal groups" (whose members were actually working alone) was greater than the number of ideas produced by real, face-to-face groups.
