Doing early-stage modeling or analysis based on GUI mockups can box you into thinking towards a specific implementation too early on in the process. But then again, you need to have a way to model the interface to the actor. What I might suggest is to make the mockups as abstract as possible, e.g.:
In this screen, the user will have a way of specifying the following information:
- name
- street
- city
- state
- zip
- country
- telephone
- a way to confirm and save the information
- a way to cancel the operation
This allows you to properly focus on the
what and not the
how which is what the following leads you to:
The screen will have the following:
Textbox for Name at (x1, y1)
Textbox for Street at (x1, y2)
Textbox for ....
Dropdown List for State at (x1, y4);
"Save" button
"Reset" button
