What's the Writing Process?

For her I think it's science first so speaking of science first many the plot lines revolve around scientific obstacles you know they have to solve some specific technical problem and you guys aren't just like fuzzing over the details. So tell us a little bit about the writing process do you guys come up with story arcs and then figure out the science to make it work or do you start with the science and the challenges presented by it and then think about how your characters will navigate it? Each season is a little different but we'll spend time in the beginning of the season during something we call blue skying where no ideas are wrong idea and we'll talk about possible arcs for the characters and directions
