Designing a GUI application: one VS multiple screens

Question

we are creating an application with the following GUI outline:

The "stuff to show for step i" changes dramatically. Would it be better to design i separate screens, each with its own controls, or put it all on a single screen and toggle the visibility of the components?

I am looking for maintainability (I will probably need to hand the screen to a designer to improve my (bad) graphic designer).

Answer 1

In my opinion it is better to have separate screen if only for maintainability. Separate screens will allow each step to evolve independently form the other with minimal dependencies as well as different people to work concurrently on the design and development of the different screens
