In reply to Osiris:
It's impressive and a useful training tool, but clearly too detailed to apply in a rescue situation.
I wonder if you could condense it to a simpler chart, or set of questions:
1. Can the casualty be lowered to somewhere safe? If yes, advance to step 3
2. If no, can you tie them off and escape? (If no, er, crap)
3. If yes, can you then get to them e.g with prussics or downclimbing? (If no, er, crap)
4. Once with the casualty, make an anchor and remove any kit from higher up.
5. Abseil together or lower the casualty as appropriate.
