The document presents ossap, a method designed to facilitate the adoption of open source software (OSS) by organizations according to their strategic goals. It outlines a situational method engineering process that helps create adaptable business process models for OSS adoption. The ossap method aims to support organizations in defining and refining their OSS-aware business processes, while also paving the way for future adaptations and strategies.

OSS Adoption
• Many commercial software products adopt
OSS components
• Many organizations are becoming OSS
adopters
• Which business processes for OSS adoption
does an organization need according to its
strategic goals?

• Help organizations interested in OSS
adoption to:
• Adaptable method: based on SME
OSSAP method goals
 Obtain strategic goal
models for OSS
adoption
 Obtain business process
models that implement
those strategies

Conclusions
• OSSAP is a method for defining OSS adoption
business processes
• Using SME to build OSSAP:
 Modular method description, all in terms of
method chunks, that can be reused
 Facilitates the future extension to adapt OSSAP to
new situations
• New emerging OSS adoption strategies
• New kinds of objectives (other than OSS adoption) e.g.
quality assurance

23. 23
Future work
• OSSAP extension
 New emerging adoption strategies
 New kinds of objectives
 Integration of the BPMN processes to the business
processes already existing in the organization
• Analyze other possible strategies to
implement OSSAP intentions: KAOS, GBRAM,
SPEM
• Validation of OSSAP in adopter organizations
