Development work, rather, its impact cannot be measured fully through merely quantitative and conventional methods of evaluation. Some might argue that such type of evaluation is the ‘best’ form of assessing a project’s performance. At one level, quantitative evaluation may seem an ‘appropriate’ way to judge, for example, an income generation project’s performance through numerical illustrations of a rise in levels of income of targeted communities in the middle, or end, of that project. However quantitative data does not capture complex processes or behavioural and attitudinal changes that might have influenced the target community to strive for higher levels of income.
