Decisions a playwright can make?

Again, through the superb Jane Bodie in my Royal Court workshop, we asked what decisions a playwright can make.

My notes read:

Who are the characters/main character?
What’s the journey? Emotional and/or physical?
What’s the setting?
What’s the message?
What’s the theme?
How do the character’s relate?
What is the conflict?

Obviously, there are many more decisions, but this little list offers food for thought.
