Nestlé Europe has a popular workout series call the “Flat Belly Program”. They were looking for a partner to develop mockups as part of a bidding process. I worked with Nestlé staff to develop a requirements document, and then to develop screens and additional documentation.
Normally I coordinate with developers, so the number of mockups and UI screens are dependent upon providing enough detail for the developers to understand the concepts. For the Flat Belly App, I developed a set of fully-realized wireframe images exploring a significant number of app screens for absolute clarity.
