You have 7 days to right an episode and the next episode and the episode after that. You don't get to change the characters or the central theme.
"South Park" allegedly turns episodes around in a week.
However... Using "Justified", new seasons start in January, as an example because I've seen those writers, producers and Olyphant and the late great Elmore Leonard interviewed about the process. By this time in February, the writers have already started writing the basic story lines for the season, casting has already begun and locations set up. By late Spring, they have full scripts and are setting up for a late Summer shoot.
Those writers have a long time to deliver their work, not seven days.
The exceptions are something like that 4th season of "Babylon 5" when Straczynski was informed he wasn't going to get a 5th, so he had to rewrite the whole season in short order to finish the series' main story arc.
(a short side trip.)
The big panic over at HBO is that George R. R. Martin is going to vapor-lock before he completes the entire "Song of Ice and Fire" series. They are turning out 10 episodes of the series, one book at a time, every year. By June of 2015, they will have run out of books to adapt... and "In January 2014, Martin’s UK publisher, Jane Johnson, declared on Twitter that the book (the new one, "The Winds of Winter") would “certainly” not be published before 2015". OK, if they can get it adapted in time, that's the 2016 season.
So Martin will have a little over one year to give them an adaptation of a planned 1500 page story? Maybe he'll do the hat trick. Maybe he's already got TWO 1500 page manuscripts almost ready and he's busy editing and re-editing them and they will be perfect and ON TIME.
