It seems that specs are like flossing: everybody knows they should be writing them, but nobody does.

Why won't people write specs? People claim that it's because they're saving time by skipping the spec-writing phase. They act as if spec-writing was a luxury reserved for NASA space shuttle engineers, or people who work for giant, established insurance companies. Balderdash. First of all, failing to write a spec is the single biggest unnecessary risk you take in a software project. It's as stupid as setting off to cross the Mojave desert with just the clothes on your back, hoping to "wing it." Programmers and software engineers who dive into code without writing a spec tend to think they're cool gunslingers, shooting from the hip. They're not. They are terribly unproductive. They write bad code and produce shoddy software, and they threaten their projects by taking giant risks which are completely uncalled for.

I believe that on any non-trivial project (more than about 1 week of coding or more than 1 programmer), if you don't have a spec, you will always spend more time and create lower quality code. Here's why.
