Very interesting. On the same note as David below, I would love to see more discussion on perception via-a-vis ACTUAL performance of services. In other words, to which extent are perceptions an accurate indicator of the quality/ quantity/ value-for-money in service delivery provision? In my experience, perception surveys suffer too often from sampling and 'cultural' bias. Certain cultural clusters might tend responding more positively or negatively by default. In my opinion, perception surveys are too often treated as a stand-alone gauge on service delivery without triangulating data or 'reality check', through let's say, observations... Thanks again for the feed!
