Nowadays, the gap between data communications and telecommunications disappears rapidly, which leads to augment of the complexity and size of supporting networks. This calls for the software developers to embrace a new way of developing management software. This is the impetus for the TM Forum’s New Generation Operations Systems and Software (NGOSS) initiative. It aims to deliver a framework for rapid and flexible integration of Operation and Business Support Systems in telecommunications and throughout the wider communications industry. The enhanced Telecom Operations Map (eTOM) is a key part of NGOSS. It plays an important role as a guidebook built on TM Forum Telecom Operations Map (TOM). The eTOM model describes the full scope of business processes required by a service provider and defines key elements and how they interact.
