Summary description

A focus group brings together a cross-section of stakeholders in an informal discussion group format. Views are elicited by a facilitator on relevant topics. Meetings can be taped for later analysis.

Typical Application Areas

Useful early in requirements specification. Helps to identify issues which may need to be tackled and provides a multi-faceted perspective on them.


Allows the analyst to rapidly obtain a wide variety of views from a range of people with widely differing but relevant perspectives.


Social factors such as peer pressure may lead to inaccurate reports. Techniques such as Delphi groups can be used to compensate for this.

Cost of use

Meeting facilities and A/V recording facilities if a video record is desirable.

Facilitators require training in order to keep meetings focused.

Useful, in that focus groups can be applied to a wide range of situations. However, the role of the facilitator is relatively constrained in this kind of technique and more interactive techniques are available.

How to get it

Widely practised. There are a few simple ground rules that the facilitators must adhere to (see below).

Detailed description of method
