Methodological challenges in the implementation and evaluation of social welfare policies

As social reality is quite elusive, even regarding seemingly well-recognized everyday concepts and objects, there are always methodological challenges underlying assessments and evaluations of implementation policies. The present article addresses this area of concern by presenting the results of a rereading of an empirical study of elderly home care services. Our results reveal the emergence of a dissolution of common and professional key concepts and objects in these welfare services to a degree that challenges both the implementation policy and the evaluation of policy. We claim that this has methodological implications for evaluation of implementation policies in general.
