Learn about the real values offered by the open source model and how to pitch it without "sounding like a software hippie".
Using open source solutions like Drupal can save you money. Hurray! The bottom line always counts, especially today. No one should be wasting money. When businesses waste money, they shut down. When governments waste money, there are much worse, much broader consequences.
But there are important reasons to use open source solutions beyond the price tag. The "Four Freedoms" that define open source software also define real business value: innovation, cost-savings, and risk mitigation. If you understand the true value in open source software and in a massively successful project like Drupal, you can bring your organization real benefits and add real value.
Let's think open source (let's think Drupal!), be its champions and explain it to our colleagues, bosses, friends, and decision makers: whether your MP, European bureaucracy, or marketing department.
