I am hopefully that flexibility is something I can manage! I work in medical research and we often spend time with researchers developing research proposals from poorly conceived ideas to ethically sound protocols....but it can be a hard road. And, in the same way as with a screenplay, if the researchers are not willing to listen to advice, they will find the path to final product is a long, winding and often painful road to negotiate. I hope that this experience will help me understand that need for flexibility and how important external feedback is.

This is a nice article and certainly eye opening. The feedback part makes sense - though how screenwriters ultimately still manage to preserve the script's integrity comes to question and is something that's a skill as well (wonder if there are any tips for that?). One thing that's nice to read though, is that 'sharing' of the process - writing can be lonely so the collaborative part, despite its pros and cons, does appeal to me in a way.
