On Process: Inside-out

With an inside out process (similar to a spiral or iterative method), you choose what seems to be the most important thing and begin with it. Constrain yourself to what is easiest to do if the requirements are flexible and speed or economy is important. Start with what's most dificult if you aren't sure that the design is feasible.

You try to make this mos important feature useful in and of itself, without any help from other things, as quickly as possible.  Once a cycle is complete then you can try to improve it or add to it in a further iteration. 

With an inside out process you might just have a phrase or title for your play that seems interesting to you for some reason. So you pursue that title, perhaps taking it a couple of different ways, in order to explore the central interest in it. Later on you might find yourself wanting to place the results into a form that you begin to see from the top-down or you might want to begin again with another piece that relates to the first in some way. If you do this, then each piece might become bottom-up components with a large grain size.
