You might as well ask a team of a dozen writers to write a novel. Yeah -- think of the odd looks you'd get -- but it's true, a piece of software is a lot like a novel, with characters, plots, background, themes, and so forth.
The problem with this analogy is that, for example, many sitcoms (Friends comes to mind) do have teams of writers. They do churn out more episodes faster. I feel that many software projects are much more like sitcoms than Paul Auster novels, not least in terms of artisticity1
1My english is obviously not at its best today. I'll let another writer on our team fix that though.
