There is a tendency in this “Information Age” to assume that everything we need to know has been written/created in the last couple of months. This is, of course, patent nonsense however in some subjects there is a rather unfortunate tendency to forget all of the huge wealth of knowledge and wisdom we have from times before … well before 2012!!
I came across an article written in 2001 (which I know isn’t that old) which is actually in a style that is currently very popular – i.e. “N things you need to know about……” – often not a terribly useful way of addressing a subject, but just occasionally someone will get it right. This particular one is called 10 Useful Ideas on Systems Thinking and is well worth a look.
