Telecom Modernization

Software Engineering: Step-by-step modernization

Swiss telecom operators face a brutal equation: margins under pressure, legacy systems that can't be switched off overnight, and a market that rewards whoever delivers new services fastest.

Do these challenges sound familiar to you?
  • Your OSS/BSS stack is slowing down product launches
  • Legacy dependencies block modernization without stopping production
  • Cloud adoption stalls on security, resilience and data sovereignty
  • Cyber obligations tighten while operational complexity grows
  • AI promises are everywhere — but measurable ROI is hard to find

At adesso Schweiz, we work where the real complexity lives: between your legacy core and your modern ambitions. We help telecom operators modernize their OSS/BSS stack incrementally, connect Cloud and data architectures that are actually operable, and automate what's worth automating – without disrupting what's keeping the lights on. Our foundation: Deep telecom expertise, local teams and hands-on delivery — proven across 60+ Swiss telecom projects.

Core topics

OSS/BSS modernization

Incremental migration of your core systems — order management, billing, provisioning – without stopping production.

AI that earns its place

From AI-assisted operations and incident detection to developer productivity tools – pragmatic AI that delivers measurable impact, not hype.

From raw data to decisions

Swiss data sovereignty in the telcom industry, unified data platforms and analytics that turn OSS/BSS data into actionable insights.

Modern engineering – legacy included

We bridge old and new: modernizing telecom applications incrementally while keeping critical systems stable and teams productive.
