Effectiveness refers to the degree in which objectives have been obtained and the extent which target problems have been resolved.
It is distinguished with no reference to cost. Effectiveness also means “doing the right thing while efficiency is about “doing such thing right”.
Another definition that may be incorporated with this word is the ability of intervention to perform more good things than harm for target population in the real world situation.
