Author a Ubiquitous-Language Glossary for a Telco Billing Domain
Overview
What this challenge is about.
You interview 5 stakeholder teams to capture 25 billing terms, identify 6-10 collisions, and write a glossary with translation rules. Get a verifiable certificate.
The scenario
The telco (around EUR 240M revenue, regulated by ANACOM) has had 3 production incidents in the last year traceable to billing terminology confusion across teams.
The Brief
What you'll do, and what you'll demonstrate.
Reconcile conflicting ubiquitous-language definitions across 5 teams in a telco billing domain and propose a 90-day remediation roadmap that avoids a forced rewrite.
Earning criteria — what you'll demonstrate
- Conduct domain interviews that surface language collisions, not just opinions
- Author a per-context glossary that handles real terminology conflicts
- Distinguish quick-win renames from structural domain redesign
- Communicate a domain-language remediation to non-engineering stakeholders
