In this phase, I take the results from the Framework Definition phase and refine the design.

Here I figure out all the nuts and bolts of the solution. I fill in the blanks in the framework solution. I create an appealing, functional visual design that effectively expresses your brand.
I describe and illustrate all the important details of the product. I determine what everything looks like and how it behaves, from query strings to list-box contents to the colors of every pixel in every icon. Designing to this level of detail makes your subsequent development efficient and predictable.
