While many projects are still designed and executed along more linear planning lines to control the production of results/outputs, it becomes increasingly obvious that systemic impact of such interventions can only be limited. Any interventions in social systems, however, will have implications, sometimes in unexpected ways, which then have to be assessed accordingly. Evaluation is one way to look at what interventions led to in the systems where they were made from the outside. The main solution presented to the dilemma - systemic evaluation in non-systemic project designs - is a different role and function of the evaluator and the simultaneous observation of process and content.
Complementary advisory (the harmonization of process and expert content) thus becomes complementary evaluation! If systemic evaluation is to alleviate the original dilemma the evaluator needs a different brief, ticket and understanding of his possibilities. He in a way takes the role of the "advisor to the advisory system" in that he helps to reflect on progress - and lack thereof - and enables the advisors to redesign their interventions. He can then follow proceedings as a temporary member of the social system - from the inside, so to say.
