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

Assembling method chunks

• Strategies used to assemble methods Integration Association

22

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

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
