Since the publication of the white paper, the group has produced several more in-depth materials, including a standard terminology definition<ref>{{cite web|last=Mulligan|first=Ultan|title=ETSI Publishes First Specifications for Network Functions Virtualisation|url=http[https://www.etsi.org/news-eventscommittee/news/700-2013-10-etsi-publishes-first1427-nfv-specifications|accessdate=5 Decemberover 2013}}</ref>100 andpublications], useto casesdevelop the required standards for NFV thatas actwell as referencessharing fortheir vendorsexperiences of NFV implementation and operatorstesting considering to help vendors and operators adopt Network Virtualization.

The group makes new specifications that meet the needs of the industry. Maintenance ensures that the specifications are referenced by all industry stakeholders, service providers, network equipment vendors and other implementers such as open source communities. Progress in the industry is monitored and includes feedback from implementation and the identification of gaps to be addressed.

During its first two years, known as the "pre-normative" phase or Release 1, the goal of the group was to drive convergence on network operator requirements for NFV, include applicable standards, where they already exist, into industry services and products and develop new technical requirements in order to stimulate innovation and foster an open ecosystem of vendors.

From 2015 to 2016, [https://docbox.etsi.org/ISG/NFV/Open/Other/ReleaseDocumentation NFV Release 2], covered the specification of models and interfaces concerning diverse capabilities for the interoperability across the NFV-MANO functional blocks (VIM, VNFM and NFVO) and towards external systems, according to the reference points specified in the NFV Architectural Framework. For an introduction to the Release 2 content and additional description about the capabilities that have been specified, see also the [https://docbox.etsi.org/ISG/NFV/Open/Other/ReleaseDocumentation NFV Release 2 description document].

The [https://docbox.etsi.org/ISG/NFV/Open/Other/ReleaseDocumentation Release 3] (2017-2018), focused on enriching the NFV Architectural Framework to make NFV “ready” for global deployment and operations, with a set of 22 new features, including three main areas, key for 5G:

* Support for the latest network technologies, such as edge computing and network slicing

* New operational aspects, such as multiple administrative domains, policy framework, etc.

* Advances in virtualization, such as cloud native VNFs, acceleration technologies, etc.

The group is currently working on Release 4.
