My Involvement in this web project was unique. I was brought on to solve the mobile experience. The initial designer left the project before the mobile experience was fully hammered out. (I would argue the mobile experience should have been hammered on Day 1, but thats another story).
I took on the project. I made myself familiar with the entire web project from goals to design to content. Along with the account team, I went in and crafted the best possible fix that can be built with the framework of the already built website. I also suggested several fixes to the user experience (most of the suggestions were implemented). The client was very happy.
