Non Goals

__Non-goals__ are things we are just not going to do. When you’re building a product with a team, everybody tends to have their favorite, real or imagined pet features that they just can’t live without. If you do them all, it will take infinite time and cost too much money. You have to start culling features right away, and the best way to do this is with a “nongoals” section of the spec.

A nongoal might be a feature you won’t have (“no telepathic user interface!”) or it might be something more general (“We don’t care about performance in this release. The product can be slow, as long as it works. If we have time in version 2, we’ll optimize the slow bits.”) These nongoals are likely to cause some debate, but it’s important to get it out in the open as soon as possible.
