Open Source Guide for Small and Medium Enterprise / Business

This is an excellent set of guides encouraging FLOSS for small and medium size enterprises / business. From the guide:

Open source software is the most significant all-encompassing and long-term trend that the software industry has seen since the early 1980s". This is one of the conclusions of a recent IDC report [IDC 06], which shows how much the perception of FLOSS (free/libre/open source software) has changed in the recent years. Right now, the majority of developers in the world are using open source software [Forr 07], and FLOSS platforms are used in one way or the other by a large share of companies.
Despite this situation, there is still a significant barrier in the adoption process for small and medium companies, both in terms of using FLOSS internally and in creating products and services centered on FLOSS products. The purpose of this report is to provide a simple and in-depth view of the fundamental aspects of FLOSS, how to adopt it within a small/medium company, and how to build a sustainable business based on it.
