Functional Framework
The Functional Framework establishes a function map supporting the business processes (eTOM) and information (SID) for a Service Provider.
Data Architecture
The Modern Data Architecture work at TM Forum is exploring how to upgrade data architecture in telecoms, analyzing tech advancements, business model shifts, market dynamics, and environmental factors to define modern architecture features for today's telecoms landscape.
