Societe Generale Uses Integration to Reduce Costs, Improve Decision-Making
Unifies separate business units
Over the years, Societe Generale’s Risk, HR, Accounting, Procurement, and other business units (BUs) had each built their own information systems to meet business needs. These systems had evolved into separate silos of technologies with no plan for reuse. The results included high development and maintenance costs and data discrepancies that ultimately impacted the ability to make informed decisions.
To overcome these issues and industrialize integration between business units, Societe Generale’s IT management decided to implement a platform to manage and govern data exchanges: the Système d’Echange Groupe (SEG), or Group Exchange System.
To build the SEG, Societe Generale needed integration technology that could address the wide variety of its technologies and a platform that would deliver high availability and scalability for enterprise-wide data exchange and business processes. Some of the bank’s business processes are highly regulated, so an open platform able to comply with corporate and industry regulations was also a requirement.
While the BUs agreed that the new integration platform needed to leverage services used across the organization, they also wanted to preserve the speed they enjoyed from point-to-point interfaces. Therefore additional requirements were added: rapid implementation of data exchanges—as well as fast return on investment (ROI).
The bank selected TIBCO’s proven service-oriented architecture components: its leading integration platform, TIBCO ActiveMatrix BusinessWorks™, integration platform, TIBCO ActiveMatrix® Service Grid SOA development platform, and TIBCO Enterprise Message Service™ messaging middleware. The IT organization applied agile development methodology and focused on delivering new functionalities in short four-week cycles. It built the SEG in just seven months. Today the SEG provides better data monitoring, standardizes the exchange of data flow serving specific business processes, and avoids redundancies that are typically the result of point to point integration.
Reduced Development and Maintenance Costs
What had been separate organizations with isolated processes and resources became a unified partnership. With well-defined data subscription and publication contracts, and using the TIBCO enterprise services bus to exchange data, the SEG has allowed simplified architectures. It has eliminated many point-to-point exchanges requiring management of many formats, technologies, and protocols, and reduced development and maintenance costs.
“Thanks to the centralization of data flow, we offer better supervision to the SEG partners,” says SEG Project Manager Gwenaël Lechat. “Deduplicating actions between data producers and data subscribers allows us to increase flexibility of systems and improve cost efficiency.”
Greater Flexibility and Efficiency
Instead of maintaining several integration systems and specialized skills for redeveloping what others may have already implemented, the BUs increasingly leverage the SEG’s integration services, including much greater services reuse, data format validation and transformation, and protocol changes. The BUs can now easily onboard new data sources without disruption. The SEG guarantees the data will be integrated without having to update any systems, and the system has improved data quality and reliability, eliminating countless validation procedures.
Fast Implementation, Higher Productivity
Speed of implementation and flexibility were fully proven even before the first services went online. The integration platform’s scripted automation of development and deployment provided excellent support for the bank’s agile methodology. ActiveMatrix BusinessWorks graphical design IDE, and its ability to use patterns for industrializing solutions to common issues, helped the team accelerate implementation. In less than a year, more than 1,000 data flows between more than 45 partners were implemented.
“The speed and scale at which SEG services were adopted shows its ability to solve real business problems and easily onboard partners,” says Gwenaël Lechat. Now that the SEG is running, the composition of services and high rate of reusability will keep development team productivity high.
Better Security and Data Quality
The SEG also addressed security and data quality across a wide array of technologies, avoiding additional costs for these systems. It improves security by authorizing data subscribers and publishers and securely processing and distributing their data. It also identifies and eliminates data duplicates, allowing BUs to focus on extracting value from data, rather than on verifying its accuracy.
Societe Generale expects data flows will increase from 1,000 to 1,600. As more data crosses SEG exchanges, users across the organization will be empowered with quality data, streamlined business processes, and more informed decision-making.
