This means that the telecommunications industry has had a reference model that covers all major business processes for a fairly long time now. The \u201cEnterprise Management\u201d area has also been added for the sake of completeness, but lacks a more detailed description and is not really the focus of the TMF.<\/p>\n<p>A mapping between eTOM and ITIL, including the assignment of the individual processes and life cycle elements, is shown below but is only a rough approximation.<\/p>\n<p><img data-attachment-id=\"604\" data-permalink=\"https:\/\/www.investaura.co\/wordpress\/2010\/11\/itil-only-for-it-part-2-of-2\/overview_etom_itil-2\/\" data-orig-file=\"https:\/\/i0.wp.com\/www.investaura.co\/wordpress\/wp-content\/uploads\/2010\/11\/Overview_eTOM_ITIL1.jpg?fit=%2C&amp;ssl=1\" data-orig-size=\"\" data-comments-opened=\"1\" data-image-meta=\"[]\" data-image-title=\"Overview_eTOM_ITIL\" data-image-description=\"\" data-image-caption=\"\" data-medium-file=\"https:\/\/i0.wp.com\/www.investaura.co\/wordpress\/wp-content\/uploads\/2010\/11\/Overview_eTOM_ITIL1.jpg?fit=300%2C300&amp;ssl=1\" data-large-file=\"https:\/\/i0.wp.com\/www.investaura.co\/wordpress\/wp-content\/uploads\/2010\/11\/Overview_eTOM_ITIL1.jpg?fit=1024%2C1024&amp;ssl=1\" decoding=\"async\" class=\"aligncenter size-full wp-image-604\" title=\"Overview_eTOM_ITIL\" src=\"https:\/\/i0.wp.com\/www.invest-aura.com\/wordpress\/wp-content\/uploads\/2010\/11\/Overview_eTOM_ITIL1.jpg?w=720\" alt=\"Overview of eTOM and ITIL\" data-recalc-dims=\"1\" \/><\/p>\n<p>The NGOSS program can best be understood with reference to the historical development of supplier-operator relationships. \u00a0Historically the telecommunications world has been dominated by proprietary solutions, corporate \u2018standards\u2019 of the manufacturers so to day, which, although largely interoperable at the network level, are not interoperable at the network management level. \u00a0So most network operators had to developed their own operations and business support environments and refine them over the years.<\/p>\n<p>For economic and competitive reasons, telecommunications network operators have been encouraging the development of standardized interfaces in network management for a long time, and requesting more flexibility in the procurement of operations support systems, to be based on standards and existing system solutions (commercial off-the-shelf software, COTS).<\/p>\n<p>There are now numerous independent suppliers of (IT-based) operations support systems and they use the TMF to position and promote their solutions. \u00a0Some people say that the TMF is \u201ca big marketing engine.&#8221; On the other hand, as a manager of BT told us recently: &#8220;The TMF is the only serious player in town.&#8221;<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Harmonization of telecommunications and IT standards <\/strong><\/p>\n<p>&nbsp;<\/p>\n<p>The telecommunications world has good reason to strive to harmonize their standards with those of the IT world, because the IT has now grown beyond it traditional support role (\u201cto provide the information infrastructure for the network and service operation and the required OSS applications\u201d).\u00a0\u00a0 IT is becoming part of almost all telecommunications products. \u00a0In addition, operational functions are increasingly outsourced, and more often than not awarded to non-specialized telecommunication providers (IBM etc).<\/p>\n<p>It would not make sense to try and map the process models of TMF and ITIL over the entire service value chain.\u00a0 It may be possible, but not adequate.\u00a0 One reason is that the eTOM &#8220;services&#8221; (services that are marketed by a telecommunications provider) and the ITIL \u201cservices\u201d use a different granularity and different perspectives. \u00a0\u00a0The most striking differences between the two worlds are:<\/p>\n<ul>\n<li>Accounting and billing plays a prominent role in the value of the telecommunications service provider. This topic is practically not represented in ITIL, as the billing of IT services follows different premises and is a few orders of magnitude less complex.<\/li>\n<li>The distinction made in eTOM between customer relationship, service and resource (network) management reflects exactly how telecom service provider processes are organised and run. The distinction between these three layers does not exist in IT and is thus alien to ITIL.<\/li>\n<li>The tasks of a service desk as understood by ITIL are distributed in the eTOM model over about 30% of all operational Level 2 processes.<\/li>\n<li>A Configuration Management Database (CMDB) is (still) foreign to the management of telecommunications networks. \u00a0SID is not comparable to CMDB; network and services inventories systems are its closest comparable,\u00a0 although the latter are sometimes quite rudimentary.<\/li>\n<\/ul>\n<p><a href=\"https:\/\/i0.wp.com\/www.invest-aura.com\/wordpress\/wp-content\/uploads\/2010\/11\/eTOM_Level2_Operations_Processes.jpg\"><img data-attachment-id=\"606\" data-permalink=\"https:\/\/www.investaura.co\/wordpress\/2010\/11\/itil-only-for-it-part-2-of-2\/etom_level2_operations_processes\/\" data-orig-file=\"https:\/\/i0.wp.com\/www.investaura.co\/wordpress\/wp-content\/uploads\/2010\/11\/eTOM_Level2_Operations_Processes.jpg?fit=%2C&amp;ssl=1\" data-orig-size=\"\" data-comments-opened=\"1\" data-image-meta=\"[]\" data-image-title=\"eTOM_Level2_Operations_Processes\" data-image-description=\"\" data-image-caption=\"&lt;p&gt;eTOM Level 2 Operations Processes&lt;\/p&gt;\n\" data-medium-file=\"https:\/\/i0.wp.com\/www.investaura.co\/wordpress\/wp-content\/uploads\/2010\/11\/eTOM_Level2_Operations_Processes.jpg?fit=300%2C300&amp;ssl=1\" data-large-file=\"https:\/\/i0.wp.com\/www.investaura.co\/wordpress\/wp-content\/uploads\/2010\/11\/eTOM_Level2_Operations_Processes.jpg?fit=1024%2C1024&amp;ssl=1\" decoding=\"async\" class=\"aligncenter size-full wp-image-606\" title=\"eTOM_Level2_Operations_Processes\" src=\"https:\/\/i0.wp.com\/www.invest-aura.com\/wordpress\/wp-content\/uploads\/2010\/11\/eTOM_Level2_Operations_Processes.jpg?w=720\" alt=\"\" data-recalc-dims=\"1\" \/><\/a><\/p>\n<p>On the other hand, if a telecom service is provided jointly by several providers, ITIL can be very helpful in order to define the interaction between the required service processes. \u00a0A Mobile Virtual Network Operator (MVNO) or Enabler (MVNE), as already mentioned, provides a good example. \u00a0Starting points for the application of the ITIL methodology in the telecommunications value chain includes:<\/p>\n<ul>\n<li>Assurance: Event \/ Incident \/ Problem Management can be partially or completely outsourced, particularly the Field Service activities;<\/li>\n<li>Fulfilment: Change Management \/ Request Fulfilment, including logistics fulfilment and therefore also Field Service;<\/li>\n<li>IT or IT-related services in general, including parts of billing and invoicing.<\/li>\n<\/ul>\n<p><a href=\"https:\/\/i0.wp.com\/www.invest-aura.com\/wordpress\/wp-content\/uploads\/2010\/11\/Application_ITIL_in_Telecom.jpg\"><img data-attachment-id=\"607\" data-permalink=\"https:\/\/www.investaura.co\/wordpress\/2010\/11\/itil-only-for-it-part-2-of-2\/application_itil_in_telecom\/\" data-orig-file=\"https:\/\/i0.wp.com\/www.investaura.co\/wordpress\/wp-content\/uploads\/2010\/11\/Application_ITIL_in_Telecom.jpg?fit=%2C&amp;ssl=1\" data-orig-size=\"\" data-comments-opened=\"1\" data-image-meta=\"[]\" data-image-title=\"Application_ITIL_in_Telecom\" data-image-description=\"\" data-image-caption=\"&lt;p&gt;Applications of ITIL in Telecom&lt;\/p&gt;\n\" data-medium-file=\"https:\/\/i0.wp.com\/www.investaura.co\/wordpress\/wp-content\/uploads\/2010\/11\/Application_ITIL_in_Telecom.jpg?fit=300%2C300&amp;ssl=1\" data-large-file=\"https:\/\/i0.wp.com\/www.investaura.co\/wordpress\/wp-content\/uploads\/2010\/11\/Application_ITIL_in_Telecom.jpg?fit=1024%2C1024&amp;ssl=1\" decoding=\"async\" class=\"aligncenter size-full wp-image-607\" title=\"Application_ITIL_in_Telecom\" src=\"https:\/\/i0.wp.com\/www.invest-aura.com\/wordpress\/wp-content\/uploads\/2010\/11\/Application_ITIL_in_Telecom.jpg?w=720\" alt=\"\" data-recalc-dims=\"1\" \/><\/a><\/p>\n<p><strong>Conclusion<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p>Service managers working in industries that do not have a mature reference model should consider the ITIL model and abstract from its IT specific aspects. \u00a0ITIL v3 is an important step to make the reference model more broadly applicable beyond the IT industry.<\/p>\n<p>The telecommunications industry, however, has a relatively old and mature service reference model.\u00a0 Therefore, using ITIL in &#8220;large scale&#8221; would not make sense.
