In a situation requiring feature ideas from potential customers, which technique is the least suitable?

In situations requiring feature ideas from potential customers, the most suitable techniques encourage creativity and the generation of innovative concepts based on direct feedback and collaboration. System archaeology focuses more on understanding and analyzing existing systems and their components rather than directly engaging with customers to elicit new feature ideas. This technique is more analytical and retrospective, making it less effective for generating fresh ideas and capturing customer perspectives.

In contrast, change of perspective, brainstorming, and the analogy technique are all designed to stimulate creativity and gather varied input, making them more appropriate for the task at hand. Change of perspective involves looking at issues from different viewpoints, which can lead to novel insights directly relevant to customer needs. Brainstorming creates a free-form environment that encourages idea generation among participants. The analogy technique leverages familiar concepts from one area to inspire ideas in another, facilitating a bridge between existing knowledge and new possibilities.

Thus, while system archaeology is valuable for understanding what already exists, it does not foster the generation of new feature ideas from customers as effectively as the other techniques do.
