Part 2 of the OSS automation transformation series focuses on Simplification, the second stage in our three-step model. Building on Consolidation, where legacy systems are integrated into a unified automation framework, Simplification involves retiring or replacing outdated assets without discarding the automation work already done. Telecoms networks are inherently complex, often made up of mixed generations of technology, multiple billing systems, and duplicated functions—typically the result of organic growth and M&A. We addresses this by enabling portability and reusability of automations. Automations are built using interface-agnostic logic, so when underlying systems are replaced, only the interface connections need updating, not the entire process. This allows operators to simplify their OSS and BSS landscapes while preserving and extending their automation capabilities. CORTEX uses a modular, microservices approach with over 200 function blocks that can be reassembled and reconnected as systems evolve. This supports graceful retirement of legacy systems, while enabling efficient onboarding of new ones, seamless process continuity, and expansion to hyperautomation. The platform is built to handle legacy and next-gen interfaces alike, so as systems modernise or consolidate, automations adapt without disruption. Simplification with CORTEX is not only about reducing technical debt—it’s about enabling scale, improving time to value, supporting reliability engineering, and preparing for future cross-domain automation.
