5. Anyway…
What is
Open-
Source?

6. ● To harness the power of
distributed peer-review and
transparency.
OSI defines Open-Source
as a process that promises:
● More quality, reliability,
flexibility, better cost control
and long-term stability.
● End to predatory vendor
lock-in.

7. Is that hard to sell
Open-Source?

8. First we need to refute
some myths.

9. “Open-Source is Insecure”

13. “Open Source
Quality is Low”

15. Coverity Scan Report

Metric Open-Source Proprietary Source
Defect Density* .59 .72
● Code analysis tool used by Microsoft, SAP, Novell, Symantec, NASA, Konami…
● Analyse C/C++ and Java source
*Number of defects for every 1k lines

17. Coverity Scan Report for Open-Source
● “8 out of 10 people surveyed are choosing Open-Source
based on quality.”
● “Open-source code quality surpasses proprietary code
quality in C/C++ projects”
● “If software is eating the world, then open-source
software is leading the charge,” Zack Samocha, senior
director of products for Coverity

18. “Nobody owns,

30. “You know when a piece of software is mature when it starts being
adopted by financial services organizations. ING Financial Services
recently moved a number of sites from Oracle Stellent to Drupal.
Among these sites are http://ing.us, the main portal for their US
market. The driver behind this migration was to move to a platform
that was more dynamic and provided faster time to market.”
