13、roved on 13 February 2006 by ITU-T Study Group 2 (2005-2008) under the ITU-T Recommendation A.8 procedure. ii ITU-T Rec. E.419 (02/2006) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Sta
14、ndardization 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. The World Telecommunication Standardization Assembly (WTSA),
15、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 Resolution 1. In some areas of information technology which fall withi
16、n ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommend
17、ation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “
18、must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation
19、 may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of
20、this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent d

Often measurements are taken because they are available
24、 not because they are meaningful. It is envisaged that the model in this Recommendation will assist carriers to direct operations areas to play a more key role in supporting the business. Network management requires real-time monitoring of current network status and performance and the ability to ta
25、ke prompt action to control the performance and resources of the network and services when necessary. It should be noted that the complete range of network status and performance parameters are not necessary for the introduction of a network management capability. 2 Need for Performance Indicators T
26、he purpose of detailing Key Performance Indicators (KPI) is to establish a strong correlation between long-established drivers for Network Management indicators and the current telecommunications industrys aggressive business focus. Increasingly, there is a change in the traditional management philo
27、sophy, wherein there is little such correlation, to an environment that recognizes the impact that operations make on organization level business objectives, such as revenue (growth and protection) and reduction of costs, etc. An essential component of implementation of the objectives of the telecom
28、munications sector is the definition and adoption of monitorable performance indicators. These indicators will help policy-makers and company executives responsible for implementing these policies to measure the level of performance achievement. Therefore, the selection of indicators to examine depe
29、nds on the specific problem being addressed. In the telecommunications sector, the problems to be addressed may include: a) large unsatisfied demand for service and non-availability of next generation telecommunications services required by business and commerce; b) poor quality of service; c) poor
30、financial performance and lack of financial resources; and d) lack of qualified manpower. Performance indicators should be used to monitor progress in first addressing and then resolving the various problems affecting the performance. 3 References The following ITU-T Recommendations and other refere

38、Answer Seizure Ratio KBO Key Business Objectives KPI Key Performance Indicators KPO Key Performance Objectives QoS Quality of Service 6 Introduction One of the challenges faced in managing networks and their services is to understand which piece of data is key for supporting business objectives. Ser
39、vice Provider Executives are fine-tuning their operations with closer scrutiny of what is actually needed for supporting their business objectives. A clear mandate is that those activities utilized by the operations personnel in supporting their work be required to have a direct bearing on those obj
40、ectives. In this Recommendation, Key Performance Indicators are intended to show a linkage between company Key Business Objectives and the daily operations of the network, as follows: Key Business Objectives are affected by Key Performance Objectives, which are measured by Key Performance Indicators
41、. ITU-T Rec. E.419 (02/2006) 3 A general framework of Key Performance Indicators has been listed. Service providers can use this information for either specific business units or at the corporate level. 6.1 Evolution of performance indicators Before the mid seventies, performance monitoring was pred
42、ominantly related to technical matters network growth, improvement in quality of service, training of technical staff, etc. With emphasis shifting from engineering to financial issues and survivability, more importance is now placed on financial indicators including profitability, liquidity, tariffs
43、, billing and collection, etc. 7 Key Business Objectives As seen in the following KPI model (clause 11), these objectives are normal for most of the telecommunications industry. A glance at annual reports from any of the companies, in particular network or service providers, will find these areas in
44、 some fashion. While most likely the revenue area is on the second page, the other areas follow in later sections. Revenue (growth and protection) and cost reduction are normally the highest priority. It is essential to note that the list is not all-inclusive but is based on those that were the most
45、 universal in definition. Key Business Objectives are derived from the business areas that are determined important for each company. Whilst the below KBOs within the model suggest a linear relationship, we realize there is also horizontal integration that occurs. The broad Key Business Objectives h
46、ave been identified as: Revenue (Growth and Protection). Cost Reduction. Improve the Customer Experience. Government Regulations. Technical and Resource Reduction. 8 Key Performance Objectives Key Performance Objectives are those in broad measurements that support the business objectives. For exampl
47、e: concerning revenue growth, availability of services or network would support ensuring revenue. However, availability of the network could be a requirement that is imposed by government regulations to ensure service. KPOs are those measures that directly support the Key Business Objectives (KBO) a
48、nd can be quantifiably measured in real time. KPOs that have been identified are: Availability. Network outage impact reduction. Integrity. Protection. QoS. Downtime. Notification. Reliability. Frequency. Efficiency. 4 ITU-T Rec. E.419 (02/2006) Productivity. Security. 9 Key Performance Indicators K
49、ey Performance Indicators are the detailed indicators measured in real time that are measurable and support directly the Key Business Objectives via Key Performance Objectives. It also needs to be emphasized that single performance indicators do not, by themselves, carry much weight or information. Most of these indicators need to be seen from a time perspective to establish whether there exists a trend towards reduction or improvement of performance. Equally, most indicators represen
