All relevant screens were skinned to brand standards, and put into an annotated UI spec document that included all interaction behaviors.
Additionally, another designer and I created a style guide to communicate layout details, type treatments, icons, color palette, and animations.
During the last sprint, we used the System Usability Scale (a tool for measuring usability), which resulted in a drastically improved score. It went from below 65 for the previous tool to 85.8, which increased usability from the 30th percentile rank to the 90th percentile.
Overall, NetApp is extremely happy with the results. The new tool is more intuitive, and increased the speed at which their sales team can configure solutions for their customer. The initial release included 700 users, and in the first week there were over 7,000 sizings performed with the new tool, and not a single call to support was made.
