Visible symptom.
In guide 87, visible symptom changes the reading of signs an ecommerce site needs a redesign, because this redesign decision changes when the team can see the specific evidence, the buyer concern, and the launch risk attached to that part of the site.
Operating question: For guide 87, what would the team do differently about visible symptom if signs an ecommerce site needs a redesign had to be defended with evidence instead of opinion?
