From the perspective of scholar Ernest Schanzer, a Shakespearean problem-play is first defined independently of the idea of a Shakespearean play and only by what the phrase problem play itself necessitates.  Schanzer chooses to consider only ethical dilemmas in the definition of problem, excluding psychological, political, social, and metaphysical problems that may develop.  He concludes that problem plays are classified by a pivotal ethical dilemma that instigates multiple opposing but equally plausible opinions from the audience.  Using this theory, Schanzer distinguishes only Measure for Measure as a Shakespearean problem play, identifying both All's Well That Ends Well and Troilus and Cressida as lacking of a pivotal ethical dilemma that divides the audience.  Schanzer does not insist in his criteria that a Shakespearean problem play must be written by Shakespeare himself, offering up Julius Caesar and Antony and Cleopatra in the place of previously recognized problem plays. 
Briefly state your position, state why the problem you are working on is important, and indicate the important questions that need to be answered; this is your "Introduction." Push quickly through this draft--don't worry about spelling, don't search for exactly the right word, don't hassle yourself with grammar, don't worry overmuch about sequence--that's why this is called a "rough draft." Deal with these during your revisions. The point of a rough draft is to get your ideas on paper. Once they are there, you can deal with the superficial (though very important) problems.
