4 Operational Excellence is not only about achieving an optimized cost position Definition Operational Excellence Operational Excellence is a philosophy of leadership, teamwork and problem solving resulting in continuous improvement throughout the organization by focusing on the needs of the customer, empowering employees, and optimizing existing activities in the process. Operational Excellence s main objective is to reduce operation cost and wastes, without affecting quality, time delivery and cost of products and services one has to offer. Provide Customer Value Empower Employees Reduce Cost Improve Processes THE OBJECTIVE OF OPERATIONAL EXCELLENCE IS TO ACHIEVE TRUE CUSTOMER VALUE THROUGH HIGHLY RELIABLE PRODUCTS AND SERVICES BASED ON PROCESSES OF OUTSTANDING PERFORMANCE Source: Opexgroep, Wikipedia, Accenture, NGMN 4

20 Operations improvements have been an essential requirement from the beginning NGMN White Paper Operations Requirements out of NGMN Whitepaper The traditional O&M functionality is seen as an integral part of this selforganising concept and as such the next generation mobile networks shall organise its own resources in an automatic and optimal manner to increase overall network quality and performance. The O&M related solutions shall also be very effective and highly cost-optimised to especially minimise the need for manual intervention and hence ongoing operator resources. Definition of requirements within NGMN White Paper drafted 2005, ratified and published by the NGMN Board in Work Groups, Projects, Taskforces based on these requirements An obvious, yet indispensable recommendation for the commercial launch of next generation mobile networks is that their self organising systems including O&M functionality must support all tasks needed to provide carrier grade quality from inception, providing a state-of-the-art standardised architecture and easily operated open and standardised interfaces. In order to minimise complexity and cost, all interfaces shall be fully open and standardised for multi-vendor equipment interoperability with the absolute minimum set of options. Where options do exist, the interfaces should be functionally able to negotiate different support levels in a fully compatible way. 20

27 Network Operator s position stated in a letter to TMF and 3GPP (issued February 2011) Starting point and challenges for Network Operators Increasing demand to maintain and improve customer experience requires full end-to-end service management and hence, multi-technology and multi-vendor network management capabilities. Automation is key - Standardization is a must Cooperative, federated interface definition: all involved parties agree on one common information framework on a certain model level and acting as an umbrella for end-to-end management purposes. This umbrella should allow for federation / integration of the various network resource information models mobile and fixed, today an d in future. The key responsibility of the NGMN Alliance is to define and align Network Operator requirements. Relevant SDO s develop standards in line with these requirements. Industry (Telco and OSS) is requested to implement these standards. management functions (OSS) network related functions Proposal and next steps Joint development of optimal interface standards (e.g. information model, transfer protocols, bidirectional message formats and semantics) supported by widely accepted specification methods and adequate tools. Telco and OSS industry must drive the development and be fully committed to the common results. Ultimate target is zero integration tax! Network Operators must clearly define and state their business and functional requirements most suitable through a common forum like the NGMN Alliance. Full letter at: 27
