This matches what we see constantly too teams ship a beautiful interface built entirely on internal assumptions, then can't figure out why activation is flat. The five-unmoderated-sessions rule is a great forcing function; it's hard to keep debating button colors once you've watched a real user get stuck on something nobody flagged. We bake user research and usability testing into every SaaS engagement for exactly this reason the roadmap always shifts once you see actual behavior instead of stakeholder opinion. That fintech dashboard example is a perfect case study for why research has to come before wireframes, not after.
