I do not agree totally with the definition above for outcome - may be we should differentiate between outcome and impacts. And we can also have different generations of impact: oucome is, in my view, the very first result of an output (product or event): the number of people attending a meeting is an outcome, or the number of people listening to a radio program is an outcome. This does not mean "per se", that these people have a) rationally understood, b)emotionally accepted the message. This understanding and acceptation could be the first generation of impact. Then we have the consequences: the use of condoms, or the boiling of water.. (if this is economically and socially feasible) = the behavior change could not occur, but it is the second generation change. Which may generate a third generation change: less diseases, for example. And so on. Anyhow, BRAVO to Jane T. Bertrand !!
