Some of the group creativity techniques that can be used are:

• Brainstorming. A technique used to generate and collect multiple ideas related to project and product requirements.

• Nominal group technique. This technique enhances brainstorming with a voting process used to rank the most useful ideas for further brainstorming or for prioritization.

• The Delphi Technique. A selected group of experts answers questionnaires and provides feedback regarding the responses from each round of requirements gathering. The responses are only available to the facilitator to maintain anonymity.

• Idea/mind mapping. Ideas created through individual brainstorming are consolidated into a single map to reflect commonality and differences in understanding, and generate new ideas.

• Affinity diagram. This technique allows large numbers of ideas to be sorted into groups for review and analysis.
