You should know SFIA

For those who aren't aware SFIA is a pre-rolled skills matrix by the British Computing Society that defines a number of skills (80 or so) and then what it means to be at each level of that skill.

For anyone involved in career planning, or defining skills matricies, or even looking at where they want to go in their own career it's a seriously useful body of knowledge.

Even more impressively you can probably get some value even out of a give minute peruse of their summary sheets and introductory booklets.
