TCS partnered with Proximus to transform Siebel Sales application on Oracle Cloud Infrastructure (OCI), delivering unmatched availability, agility, accelerated time-to-market, optimized costs, and a foundation for AI-driven innovation.
Algemene beschrijving (incl. samenvatting van onderstaande vier punten, deze beschrijving wordt gepubliceerd)
Proximus, Belgium’s leading telecom provider, partnered with TCS to modernize its fragmented Siebel Sales landscape and deliver a seamless omnichannel experience. By migrating nearly 30 Siebel environments to Oracle Cloud Infrastructure (OCI) with Oracle Exadata Cloud Service, TCS unified the architecture into a resilient, scalable platform that now powers 24/7 digital sales.
The cloud based transformation boosted performance and availability, improving uptime from 98% to 99.9% and reducing operational costs. It also accelerated transactions, minimized outages, and strengthened customer and sales agent journeys. With the modernized stack in place, TCS is leveraging the Siebel GitHub AI Tool to drive faster, higher quality innovation.
Proximus is now building toward next gen capabilities using Oracle’s AI enabled ecosystem, focusing on advanced analytics, intelligent workflows, streamlined product lifecycle management, and higher order volume support for its growing B2B segment. Generative AI will further enhance sales and product development, ensuring agility and competitiveness in a rapidly evolving digital landscape.

• Large-Scale Environment Migration of 30 Siebel environment each with unique configurations, integrations, and customizations made the landscape inherently complex.
• Transitioning to Oracle Cloud Infrastructure (OCI) required a complete redesign of compute, storage, networking, and security layers to ensure enterprise grade performance, scalability, and resilience.
• Achieving uniform configuration alignment and maintaining strict deployment sequencing across multiple environments demanded highly coordinated planning and controlled execution to avoid regression or misalignment.
• Siebel’s deep integration with key systems—CPQ, Billing, Product Catalog, Order Management, Digital Channels, and Middleware—posed potential risks of broken interfaces, API mismatches, and performance degradation.
All the highlighted complexity and risks were effectively mitigated through strategic planning, rigorous impact analysis, and cross functional coordination throughout the migration lifecycle.
