This pocket guide to SOP is well written and gives a great overview of the SOP process, as well as advice on how to start setting up an SOP system. With only 55 pages of text in A6 format, don't expect great detail, but if all you need is a good summary of the process then look no further. It's a great little guide. My only complaint is the size of the text. I needed a magnifying glass to read it !. I wish the author would scale it up to A5 so anyone over 20 has a chance of being able to read it. The tables of data are miniscule. Other than that it is an excellent introduction to SOP.
