Linux for Business People is intended to introduce Linux to those involved in selecting systems for businesses to use. It is not, per se, aimed at IT staff instead at the decision makers above them.
The first section of the book provides practical experience of using Linux based systems, whilst the final half examines the experiences of companies already using Linux.
The two sections of the book have been kept completely distinct (i.e. you need not read the practical section to understand the Business Case sections), and are (hopefully) written in a way that will be understandable to even the most tech-illiterate of mangers.
Also available on Amazon Kindle.
