Side-effects

From EvaluationWiki

Effects of an intervention that are other than those that the intervention was intended to produce. They may or may not be unexpected (most programs have the side-effect of hiring a staff and hence increasing employment in the community, but this is not unexpected-it's just 'not the point,' not part of the aim of the program). Normally, side-effects are registered on the target population, but see side-impacts.
