Open Source in Practice at SNS Bank
0 likes783 views
SNS Bank has transitioned to using open source software over time, starting in 2004 when they primarily used proprietary software. They have implemented a "Straight Through Processing" strategy using the open source JBoss application stack and jBPM business process management software. An initial project implemented savings product purchase processes in jBPM, which are now available online. Further projects expanded the number of products and implemented additional bank service processes in jBPM. SNS Bank continues working to migrate systems to newer open source versions and integrate development tools to improve their use of open source software for business process management.

- 15. STP future with FOSS • Soon payment products (incl. grouping products) • Hundreds of service processes “Ook serviceprocessen die voorheen via een bankmedewerker op een filiaal verliepen, zoals de verhoging van een opnamelimiet, eenmalige opname van een bijzonder hoog bedrag en klachtenbehandeling, worden gedigitaliseerd. SNS Bank maakt gebruik van een backoffice die realtime via het web beschikbaar is.” -- Alexander Baas, Computable, Aug 2008

- 17. First project issues • immature jBPM monitoring console • lacking features (re-enter process from extern source) • interaction with process via custom task interface
- 18. Enabled with FOSS First project wins: • extended jBPM Manager Service • via jBPM API • custom jBPM Monitor Application • via jBPM API • custom task interface for fall-out • technical / functional
- 19. A different view? Katsushika Hokusai
- 20. Reference project results Enabled with FOSS • state-proxy to further customize wait-states • custom jBPM class loader (maven) • custom process testing framework • custom maven plugin • generates generic project framework
