Logic model Brief history of evaluation and the logic Model
Scriven (1991) would argue that evaluation has been around for many years, and is only now recognised as a discipline. He would go further and say it is like a knowledge which has been around for a decade before we were discussing its use, nature and logic. It is essentially different from science in its methods and thought. He would argue it is only recently we have appreciated its value as a discipline we still have a long way to go. Despite the current popularity of logic Models they date back to the 1970s. The first publication that used the term “logic model” was quoted as Evaluation: Promise and Performance by Joseph S. Wholey (1979). Suchman (1967) is similar to
All people possess strengths upon which they can build. Empowerment is a lifelong endeavour. Personal knowledge and experience are effective and useful in managing.
McDougall (1997) suggests “empowerment is not an intervention or a strategy. Rather it is a fundamental way of thinking”. “Empowerment is not giving people power; people already have plenty of power, in the wealth of their knowledge and motivation, to do their jobs magnificently. We define empowerment as letting this power out” (Blanchard, K 1960).

As we can see from some of the definitions of empowerment that the individuals carrying out the evaluation themselves need to be committed to the values of equality and social inclusion otherwise the outcomes may be affected highlighting one of the weakness of the theory and logic model where we can have unexpected outcomes, and influences we may not have anticipated.
