Re-visiting the financial benefits of Managed Services and Infrastructure Sharing

Read our latest White Paper and learn more about the following topics:

  • Managed Services / Outsourcing
  • Infrastructure Sharing (Passive, Active) / TowerCo business
  • Vendor financing, Leasing (Finance lease, Operating lease), Sale & Leaseback
  • Financial Simulation, Top-Down Modelling
  • Telecom Economics, OPEX reduction, CAPEX reduction, Value creation


Communications service providers (CSPs) in developed markets are facing considerable challenges. While voice markets are saturated in most countries, 3G/4G network rollouts require large investments, which are not always commensurately compensated by increases in revenues; data traffic is exploding but revenue per Mbyte is often decreasing faster than cost per Mbyte. The overall impact is that both EBIDTA and EBIT margins are decreasing.

The TeleManagement Forum (TMF) Framework

Unlike the ITU-T, the TMF is not a traditional standardisation organization but an independent industry consortium of telecom network operators, manufacturers and service providers. This is probably one of its greatest advantages, as it can overcome the traditional slowness of other telecom standardization bodies.

This brief article is not meant to be an introduction to eTOM, as the TMF provides an excellent primer for this purpose.  We are proud to be a member of the TMF, and advise our clients on the content and application of the various TMF ‘standards’.

The TMF has launched a series of complementary frameworks and initiated a number of marketing activities, with focus on the management of telecommunications networks. These frameworks are as follows:

  • NGOSS (Next Generation Operations Support and Software) has set itself the task to provide telecom operators with interoperable solutions for managing their services and networks
  • eTOM (enhanced Telecommunications Operations Map) is the process model behind all activities of the TMF, and obviously takes a very telecom-specific view of the business processes of an operator
  • TAM (Telecom Applications Map), a non-binding blue print of applications or application functions of OSS that are necessary for the implementation of the eTOM processes
  • SID (Shared Information / Data Model), a range of object-oriented information models that describe the interfaces between OSS or applications (as defined in TAM)
  • A number of other activities, such as technology and showcase programs that are designed to demonstrate the interoperability of OSS solutions, and certification of OSS solutions for compliance to the TMF standards

ITIL: only for IT? (Part 1 of 2)

Translated from an original article written by Thomas Bez, TEDESCA Consulting,


A service management project – whether it be the restructuring of a service unit, the development of SLA and the set-up of a Service Level Management, or a service outsourcing – rarely follows a textbook format.  However, the usage of a methodology or reference model (also called framework or blueprint) is absolutely essential. Reference models are usually developed in a particular industry, and, if they are successful at all, further mature over time with the addition of new releases.  Many of you might still remember the now extinct “FCAPS” reference model from the telecommunications industry, a fairly simple process model from the ITU-T M.3400 standard with its five functional areas: Fault, Configuration, Accounting, Performance and Security Management.

It is not unusual for these reference models to become more widely used during the course of their development, or at least to give the appearance that their concepts are applicable beyond their industry of origin.  We are particularly familiar with two of these frameworks:

  • ITIL (IT Infrastructure Library), a collection of “best practices” or, as recently more modestly described, “good practices” in IT service management – today indispensable in the IT service area.
  • eTOM (enhanced Telecommunications Operations Map) from the TeleManagement Forum (TMF), which is more and more becoming the de facto standard for the design of business processes in the telecommunications industry.

In this article, we want to show how ITIL is becoming universally applicable for service management purposes beyond the IT industry, and in particular in the telecom sector where it can be used in parallel with the standards of the TeleManagement Forum.
