knowledge barriers, forking, legacy integration, sunk costs and technological immaturity are reasons for organizations not adopting the open source software

What is Open Source Software?
Source: Wikipedia, sorry none from class, but we need to know it and their definition is simple
Open-source software (OSS) is computer software with its source code made available with a license in which the copyright holder provides the rights to study, change, and distribute the software to anyone and for any purpose.[1] Open-source software may be developed in a collaborative public manner.
see slides 5-10 for very complex definition with criterias for qualifying for open source software
Mention the 3 open source business models?
- The service model
Third-party service providers (100%)
Software producers (partly, often 25-50% of revenue)
Distributors (partly, often more than 50% of revenue)
Offer training, support, implementation assistance, operations (ASP, Cloud, ….) - The value added distribution model
Distributors: selling standard version of existing products together with a well-defined set of services typically at a yearly subscription fee. The double license (commercial OS license) model
- Software Producers: revenue from a commercial “professional edition” of the OSS product
Software producers (commercial) supporting particular OSS products
IBM supporting Linux, Eclipse. Oracle (Sun) supporting OpenOffice, Java, ….
Microsoft supporting Drupal (CMS), SAP supporting MySQL, Eclipse, …
… in some cases selling and making profit on “derived products”
