I can't draw so when it comes to webcomics I always start with an outline.
When we started Remedy I actually gave the people I was working with 4 different comic choices; or four different outlines if you prefer.
They unanimously chose Remedy (I was leaning that way myself despite my affection for several of th e other tales).
The outlines are usually just three or four paragraphs describing the main characters and the main theme of the comic with a bit of discussion related to what kind of comic it will be (comedy, action, fantasy, and so on).
Once that was done And the decision made then I spend a lot of time thinking about my main characters. I write the profiles that give not only a physical and historical description but also an emotional tendency.
Once I have my characters created I take my outline and I think about the story long term. This where new story arcs and characters and themes that never occurred to you before tend to come up. This is the Bible and it becomes a living, changing document that guides the storyline for... well in my case years worth of comics.
Then from there I fill in any character profiles I need to add and start writing comics. If a story line occurs to me that isn't in the bible I'll pull out the bible and see if I can fit it in without futzing the timeline or making circumstances too convoluted. If I can... in it goes and a new version of the Bible is born.
That's my process. Patent pending.
