My experience has been that paper prototypes are the fastest way to get mobile apps built.
That said, I'm interested in getting more exposure to the thought process other UX professionals went through at a high-level to define the flow of an app.
As a result, I'm looking for suggestions on how to find professional grade examples of:
- mobile usecases,
- mobile user-stories,
- mobile flowcharts,
While not amazing visually, here's one example of what this might mean, but please do not read to much into it as an example other than it might provide some proof that I've already done some research on the subject: Mobile Device APIs Use Cases.
