The "Holy Triangle"

[molex]

A contractor introduced me to this concept, I thought it was brilliant:

Draw a triangle on a piece of paper: On one side, write "Fast", on second side write "Cheap" and on third side write "High quality".

When looking at purchases/projects, everyone wants "the holy triangle": Fast, cheap and high-quality. The problem is, unless you're damn lucky you can only ever get two of the three sides. You want fast and cheap? Quality suffers. You want fast and quality? That ain't cheap. You want quality and cheap? Be prepared to follow someonelse's schedule.

I just thought it was a nice, clean way to show people why they can't have it all.
