Today I came across the (virtual) file of a "quick and dirty" evaluation I carried out a while ago. That made me feel a bit queasy - because I should have turned down that offer, or advised my clients to go for something radically different. Quick and dirty can be quite wasteful.
Someone had approached me for the job at very short notice - the expectation was that the consultant would start travelling within a couple of weeks. I happened to have time - some other assignment had been postponed - and I found the subject matter interesting. That's why I accepted the job. I was worried about the terms of reference, though. They came with plenty of specific ideas as to how the evaluation would have to be carried out - including requirements to visit three countries, to conduct a survey and to complete the job within some 30 person-days spread across two months. Within that time frame, the relevance, effectiveness, efficiency and sustainability of a project covering several rural areas across three countries was to be assessed. Oh, impact, too, but I talked them out of that.
