Question: How many evaluators does it take to change a light bulb?
one to do a needs assessment
one to do a feasibility study
one to do a qualitative study to find out what bulb to change
one to empower the bulb to change
one to tender a contract for further study
one to write performance indicators for success
one to do a cost benefit analysis to determine the best to buy
one to do a meta-evaluation showing that all previous studies have left everyone in the dark
SO.......how many evaluators does it take?
None, actually. Evaluators don't change bulbs, that's an implementation problem!
