This modeling has required different techniques to move from as-is BPs to to-be
BPs. We have categorized these techniques into: (i) reverse engineering the legacy
information system and mapping the enterprise service portfolio, (ii) extracting ser-
vices from traces of running business processes, and (iii) reusing partner and provider
services. Then, we have sketched out the process of each technique.
This is a step towards moving SOA maturity towards the next levels, where ser-
vices are part of the requirements and the solutions as business-related services and
IT-related services respectively. This would promote integration, composition, flexi-
bility, and agility in response to changing business events.
Although, we have presented approaches and processes for transformation tech-
niques having a real impact on the way BPs should responsive to the changes in the
business requirements by using web service-based SOA, this work has limitation.
Therefore, we would consider that this work has presented the service-oriented busi-
ness process as rather a roadmap towards research issues and questions related to
transformation techniques than a definitive solution.
We need to develop tools and dig deeper in the different transformation tech-
niques.
Further work would complete the close the cycle with the forward engineering
phase by using MDD, as services define both the requirements and the solutions.
