Peter Checkland and SSM7, originally uploaded by jjn1.
Last Friday, I went to Lancaster to take part in a symposium organised by the Lancaster University Management School to honour my friend and mentor, Professor Peter Checkland (seen here with a photograph of himself inspecting an ancient Indian locomotive). It was a stimulating, intriguing and enjoyable event. The pdf of my contribution is available here. (It explains the enigmatic heading over this post, btw.)
