From the pioneer age in the early 80, open-source software (FLOSS) has gained a strong momentum in the software industry both for internal use and for creating commercial systems, by big industry actors as well as SMEs. FLOSS entails a “paradigm shift” in the software industry, giving birth to many new business models.

As a starting point QualiPSo organised a workshop with focus on problems that occur when industry wants to integrate Open Source into their products and solutions. These encompass legal aspects, like licenses, IPRs and liability, quality problems concerning technical aspects and process aspects, and aspects concerning strategies of industry towards Open Source communities, but also of public administrations and SMEs offering Open Source as parts of their solutions. The workshop result used scenarios to identify the problems and their circumstances.

QualiPSo elaborated two state of the art reports:

• On strategies for industry and Open Source communities. They encompass problems of diverging evolution lines of industrial systems comprising Open source on one side and of Open Source systems on the other side. Further they take regard to psychological aspects and different interests between big industry, small industry, and Open Source communities.
• On the typology of the business models used in the industry for drawing revenues from open-source software. The typology consists of the following models: (i) independent software vendor business models, (ii) ecosystem enabler business models, (iii) software as a service vendor business models, (iv) service provider business models, (v) combination of OSS components with hardware, (vi) brand selling, (vii) advertisement, (viii) global fee redistributed to authors. In two more chapters, the report presents case studies related on the one hand to big industry actors, and on the other hand to SMEs.
