Not using UML yet ?

Is that possible ?

I was going over some archival messages at stackoverflow the other day and came across a post about different technologies being used in organizations. I was surprised to see a low turn out in the UML column. Not using UML in your projects is akin to building a house without a blueprint. Possible, but highly risky.

Not to mention how to fix that leaky water pipe five years down the road (what pipe ?).
