An even shorter Executive Summary:
(of pages 9-12 of the PDF article)
FLOSS role in the economy
* FLOSS applications are first, second or third-rung products in terms of market share in several markets
* FLOSS market penetration is also high
* Almost two-thirds of FLOSS software is still written by individuals
* Europe is the leading region in terms of globally collaborating FLOSS software developers
* (more details on specific role in Europe in paper)
Direct economic impact
* The existing base of quality FLOSS applications with reasonable quality control and distribution would cost firms almost Euro 12 billion to reproduce internally... code base has been doubling every 18-24 months
* This existing base of FLOSS software represents a lower bound of about 131 000 real person-years of effort that has been devoted exclusively by programmers... it represents a significant gap in national accounts of productivity
* Firms have invested an estimated Euro 1.2 billion in developing FLOSS software that is
* made freely available... represent in total at least 565 000 jobs and Euro 263 billion in annual revenue
* FLOSS-related services could reach a 32% share of all IT services by 2010, and the FLOSS-related share of the economy could reach 4% of European GDP by 2010
