M.3050/Suppl.4 (02/2007) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in t

10、he field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.

11、The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolutio

The telecom industr

30、y is facing unprecedented churn and the struggle to remain profitable in the face of more competition, higher customer expectations, falling market share and growing price pressures. The industry has a need to clearly define and understand the business processes involved in order to tackle these iss

31、ues. It also needs to reach a consensus on the common process view for equipment suppliers, applications builders and integrators to build management systems by combining third party and in-house developments. The enhanced Telecom Operations Map (or eTOM for short) is an ongoing TM Forum initiative

32、to deliver a business process model or framework for use by service providers and others within the telecommunications industry. The goal is to set a vision for the industry to enable it to compete successfully through the implementation of business process-driven approaches to managing the enterpri

33、se. This includes ensuring integration among all vital enterprise support systems concerned with service delivery and support. The focus of the eTOM is on the business processes used by service providers, the linkages between these processes, the identification of interfaces and the use of customer,

34、 service, resource, supplier/partner and other information by multiple processes. The TM Forum eTOM business process framework is a reference framework for categorizing all the business activities that a service provider will use in a structured manner that allows these to be addressed at various le

35、vels of detail. For such companies, it serves as the blueprint for process direction and provides a neutral reference point for internal process re-engineering needs, partnerships, alliances and general ITU-T Rec. M.3050/Suppl.4 (02/2007) 3 working agreements with other providers. For suppliers, eTO

36、M outlines potential boundaries of software components to align with the customers needs and highlights the required functions, inputs and outputs that must be supported by products. A particular strength of eTOM as a business process framework is that it is part of the TM Forum NGOSS (Next Generati

37、on Operations Systems and Software) program and links with other work under way in NGOSS. So, eTOM defines a telecommunications service provider business process framework. This means that it is oriented to SPs in the telecommunications sector (although it has been found to be useful in other areas

38、also) and it aims to provide a business-oriented view of the SP enterprise. This view is useful for planners, managers, strategists, etc., who need to view the enterprise in business terms without immediate concern for the nature of the way that these business needs are organized or automated within

39、 the business. Therefore, eTOM emphasizes issues such as process structure, process components, process interactivity and the business roles and responsibilities to which these relate. In defining these aspects, eTOM also provides a basis for setting requirements for system solutions, technical arch

40、itectures, technology choices and implementation paths but it is neutral towards the particular way that these requirements are met. Thus, eTOM can be considered to have two faces: one oriented towards the business, customer, products, etc., and one towards solutions, systems and implementations sup

41、porting the business. It should be recognized that, through the TM Forum work, eTOM represents an industry-consensus on the service provider processes, which has been harmonized across the global scene and is based on member contributions. It is allowable, and indeed expected, that this will mean th

42、at eTOM must be tailored and/or extended for use within an individual company. In particular, eTOM does not seek to constrain the way that the processes fit into a specific organization. An advantage of this positioning of eTOM as a framework, rather than a directly-implemented specification, is tha

43、t differentiation amongst eTOM users is not restricted, which is vital to allow specialization and competition. In addition, as already mentioned, eTOM does not fix upon particular routes to implementation and is thus valid in many different environments with varying levels of automation, technology

44、, etc. So, eTOM is a framework, not a final implementation specification. It will typically be customized and extended by users for their own business needs but provides a vital common reference that is industry-recognized and represents a de facto standard, and now, through ITU-T, an official stand

45、ard within and between companies on business process definition. 5.2 Where did eTOM come from? Work on business process modelling by the TeleManagement Forum (formerly the Network Management Forum) began in the early 1990s with the Service Management Automation and Re-engineering Team (SMART) that g

46、athered worldwide service provider views and distilled an initial business process model. This work grew in the Telecom Operations Map (TOM) during the mid-90s, leading to the stabilization and publication of TOM in its final form towards the end of that decade. The TOM work gained wide industry sup

47、port but the scope of the TOM model did not cover the whole of the SP enterprise and only focused on the main operations processes embodying the traditional telecoms activities around fulfilment, assurance and billing (FAB). Increasingly, the complexities of interworking in the deregulated, competit

48、ive telecoms market required a complete enterprise view, and new business demands triggered by the Internet, and electronic commerce generally, led to a move to expand TOM to address this wider perspective. Thus, eTOM for enhanced TOM was initiated as a work programme led by TM Forum as we entered t

49、he new millennium. Initial releases of eTOM were provided to TM Forum members during 2001 and then a TM Forum-approved version of eTOM GB921 v3.0 was released in mid-2002. 4 ITU-T Rec. M.3050/Suppl.4 (02/2007) This was welcomed and adopted widely and so further work to cement agreements, incorporate industry feedback and extend the level of detail described resulted in further intermediate versions and then a new TM Forum-approved version early in 2004. This version GB921 v4.0 was also submitted under a liaison agreemen
