A good list and a constructive one.  But the list does not leave too much for the imagination to work with.  As good an as indeed important story building is, or how believable, all relieghs on the individual author.  When and ehere something is important to the story, weather that be the character, the back story etc, then these things do need to be developed.

Other than this, the mind of any creative author aught not to be constricted to askig so many questions or focusing on so many aspects that they can not even begin to get or be creative in the first place. I do sypathise with a comment made about a character suddenly having their name or size changed.

This happens to me a lot when I write my stories, so yes it's important to keep track of the character's name, or place name, etc so at least the story is consitant.  A common and widely mistake which I am sure happens to us all as it does with my self, is refering a male character to a she and sometime a female character to being a he.

Other than thes comments, some of your list is usuful and I have at least made a top 15 out of your list, of the questions that I feel that are important and are at least of some use to me, thank you.

 Some of the list is good but all characters are not full time in the story ..  some are there for background and setup the story for the main thought to be conveyed and the background characters do not need all this list at all ... some of my stories have a high school full of kids .. that is the background plan when the main character is pushed or shoved into a locker by the rush of the kids ...you don,t have to name every kid in the hall at the time .. there would never be a short story .. thank you for your thoughts ...Rone

That's quite a list, and I don't think I could answer anywhere near even half of those questions about any of my characters, including those in my longest stories, like "Purse Snatcher" or "Girl for a Spell."

For a short story, you don't need to do a lot of characterization.  There isn't time for it.  Just get a basic notion of who the characters are.  Part of the usefulness of plotting a story out ahead of time is that, as you do so, you have to ask yourself the primary question about characterization: what makes a given character act the way they do at that specific point in the story?

The way I work -- which is okay for me, but may not be the way for everyone -- is to get a short basic description of the character's personality in my mind.  Amy Bowlan in "Swim Date," for example is "friendly/mischievious."  If I modify the character during the story, I make a note (and go back through the story to try for consistancy).

It is useful to write some things out: physical description and other specific facts.  It doesn't work to describe a character as a short slender brunette on page 1 and a tall, voluptuous blonde on page 42.  It's also useful to keep track of relationships and names, so you don't swap boyfriends or call a character "John Dixon" on page 7 and "Joe Nixon" on page 38.

This is also useful if you might use the same characters or settings again.

My basic suggestion is to try out different methods, from ultrolong lists to a quick little phrase, and see what works best for you.  Keep in mind that even this may change between the 7,500 word short story and the 75,000 word novelette.
