Before you start writing anything like a script you should know your characters and locations as thoroughly as you knew your fellow pupils at school and your work colleagues at work. And you should know all the locations as thoroughly as if you had photographed them or built them yourself.Then write an outline of your story or first episode of your sitcom series; this is called a treatment. Then break that outline down into the scenes that you will need in order to make the audience visualize that story.
Download the following template: http://www.datahighways.net/dhl/downloads/w2000/Cards.PDF
Which is the Script Development Cards template from my Scriptwriters' Toolkit.
Print out as many cards as you need, there's a guide to how many on the first sheet. Then write out one card for each character, each location and each scene from your breakdown. Shuffle the scenes around into the best logical or visual sequence (that why they are separate cards). Identify the key scenes of part 1, part 2 and part 3 of your episode and make cards for them, and identify the climax scene and write out a card for that.
Keep the cards with you wherever you go, jot notes on them every time you think of something significant. Then read them all through in sequence one evening, go sleep on it and then the next day you should be ready to type the first draft of the script of your episode. If you've done the research thoroughly writing the script and especially the dialogue will be dead easy, it will just flow from your fingers as if you were telling a story about your school friends or work colleagues.
And for those of us who don't suffer from OCD?
There are as many ways to approach writing one's sitcom as there are sitcom writers. Personally, if I followed the above method I would probably a) have a nervous breakdown (yes, another one) and b) produce a piece of joyless, derivative and formulaic shit (and I can do that perfectly well using my current methods).
