Technical people? Hell, even us blokes writing the software have no clue. I have 20 years in this, but guestamating costs and timelines? Nope. I'm a little better, but I mean, graduating from t-ball to little league.

The only time I hit it on the head, is when I'm doing a project, the type of which, I've done before. And I tend to avoid those.

I still use the rule that my mum taught me: Take your best guess at how long you'll take to do the job, and double it. That's the number you tell your team. Double that, and that's the number you tell the client.
