From efficacy to efficiency to effectiveness - Sjon van ’t Hof

“When I first read Churchman’s ‘The systems approach’ I was missing a bit of structure to let everything fall into place. I went on to read more of his books and other systems books to get to grips with the subject. I gradually became convinced that perseverance won’t harm a person bent on getting to the bottom of systems thinking. I am currently rereading the same book (‘The systems approach’) that I started off with a couple of years ago and I believe I have made some progress since then. So here is my new version of my reading and interpretation of ‘Chapter 2. Efficiency’ (pp. 16-27). It provides an alternative way for quickly understanding what the systems approach is about, by situating it in a context of other approaches most people are more familiar with.”
