  Group brainstorming is a well-known idea generation technique, which plays a
key role in software development processes. Despite this, the relevant
literature has had little to offer in advancing our understanding of the
effectiveness of group brainstorming sessions. In this paper we present a
research-in-progress on brainstorming while walking, which is a practice built
upon the relationship between thinking and walking. The objective is to better
understand how to conduct group brainstorming effectively. We compared two
brainstorming sessions, one performed during a mountain walk, the other
traditionally in a room. Three preliminary findings are obtained: walking can
lead to an effective idea generation session; brainstorming while walking can
encourage team members to participate in and contribute to the session in an
equal manner; and it can help a team to maintain sustainable mental energy. Our
study opens up an avenue for future exploration of effective group
brainstorming practices.
