Customer feedback drives some of the feature priority, and some are driven by the industry and where it is going overall.

However, they do not put too much attention on feedback because a small loud minority might be able to force a huge backlog of ideas that don't add a lot of value.

Instead, they carefully sort through all the ideas, and evaluate how those fit into their overall road map. Then, the team spends about six weeks working on each large feature, building and refining it along the way.
