it is very important to use IT to promote its competitiveness OSS is generally considered as a basic EIS which can also support knowledge management OSS market and applications are growing Taking the Asia Pacific market as an example, it generated $8.8 billion of revenues in 2002 Revenues show an increasing trend and the market for OSS is expected to grow at a steady pace The compound annual growth rate (CAGR) of the revenues for the period 2001–2007 is forecasted to be 6.27 per cent Industry revenues are forecasted to rise to $11.87 billion by the year 2007 Although OSS has been acquired by many telecom companies, the shortage of scholastic research on OSS is obvious (Li et al., 2003a) IEEE Xplore provides full text access to IEEE transactions, journals, magazines and conference proceedings since 1998, plus select contents back to 1950, and all the current IEEE standards Most of the academic publications in telecommunications are included in IEEE Xplore Using operations support systems as key word, our search matched 189 of 1043417 documents In these 189 documents, there is only one paper related to the word knowledge Searching other academic journals, such as Decision Support systems, Expert Systems with Application, Knowledge-Based Systems, Computers in Industry, Expert Systems, Data & Knowledge Engineering, Advanced Engineering Informatics, Logistic Information Management, Information & Management, Telecommunications Policy from 2003 to 2005, no papers on OSS are found There are some whitepapers Copyright ß 2006 John Wiley & Sons, Ltd 178 Syst Res about OSS at www.tmforum.org, but they are not typical research papers Knowledge may not show its significant value until it is embedded in software products or business processes Only then can its value be fully utilized OSS is the basic software platform to support value chain management for the telecom industry OSS should be the enabling tools to fulfil effective knowledge management How could this objective be achieved? The purpose of this paper is to explore a possible answer to the question The paper is organized as follows ‘Knowledge Management in Systems Perspectives’ section presents the implication of knowledge management in systems perspectives The relationship among data, information and knowledge, as well as the relationship between knowledge management and EIS is discussed In ‘Overview of OSS and Knowledge Management in OSS’ sections, an overview of OSS and the knowledge management in OSS is discussed ‘Discussion and Conclusion’ section provides a summary of the paper and future research KNOWLEDGE MANAGEMENT IN SYSTEMS PERSPECTIVES A system is made up of a set of interacting elements sharing a particular purpose within a boundary The interaction among elements forms the structure of a system Depending on its boundary, a system can be an economic entity, an inventory system, or a business organization Knowledge management is an element of the organizational management system (Warfield, 1989) From the point of view of the concept of whole, a knowledge management system promotes the effective use of knowledge assets of an enterprise as a whole over time, and is an impetus to the performance of the enterprise Data, Information and Knowledge Prior to discussing knowledge management, the terms such as data, information and knowledge must be defined The following is a

information and knowledge the distinction between data, information and knowledge: Data are known facts that can be recorded and that have implicit meaning (Elmasri and Navathe, 2004) Information is data placed in a meaningful and useful context after that has been processed (O’Brien, 2005) Information is useraimed, providing values and existing in the eyes of the beholder (Spiegler, 2003) Knowledge is information synthesized and contextualized to provide further value for human activities (Pearlson and Saunders, 2004) The relationship among data, information and knowledge can be depicted as shown in Figure Data is the abstract description of objects and is the raw material that is used to generate useful information and knowledge Information is a flow of processed data after being processed Knowledge involves the capacity of gathering and using information Knowledge becomes information when it is articulated or communicated to others in the form of text, computer outputs, speech or written words (Alavi and Leindner, 2001; Spiegler, 2003) Data warehouse is a large-scale storage facility for data Knowledge warehousing is an extension of data warehousing to facilitate the capturing and coding of knowledge and to enhance the retrieval and sharing of knowledge across the organization (Nemati et al., 2002) Online Analytical Processing (OLAP) is a software application used to explore the data in ways that are decision oriented (Shi et al., 2005) Data mining (DM) tools Copyright ß 2006 John Wiley & Sons, Ltd Knowledge Management in OSS allow for the creation of

findings In this paper, knowledge management is studied in terms of systems theory and the perspectives listed in Table will be synthesized It is emphasized in this paper that knowledge management can be used to effectively manage corporate knowledge assets especially those knowledge in business processes Therefore, the objective of knowledge management is considered to promote an enterprise’s core

the structure of the system, and the function of the system Main Factors Influence Knowledge Management Knowledge management system is a system to effectively manage knowledge within an enterprise Two main factors are considered influencing the needs of practicing knowledge management The first factor is competition If there is a tough competition in a certain industry sector, managing knowledge is generally in high demand The other factor is the volume of data If there is a huge volume of data that exist within an enterprise, the data resource is available which can help convert data into information as well as knowledge Elements of Knowledge Management System Knowledge architecture, knowledge management process architecture, organization architecture and IT architecture are the four elements of knowledge management system The so-called knowledge architecture is the result of classifying organizational knowledge by one or more dimensions Fernandez et al distinguished knowledge into human knowledge, organizational knowledge, technological knowledge and relational knowledge (Fernandez et al., Copyright ß 2006 John Wiley & Sons, Ltd 180 2000) Human knowledge refers to the knowledge acquired by a person that can increase productivity and the contribution to the organization It also includes other individual qualities such as experience, judgement and intelligence A firm’s organizational knowledge includes its norms and business guidelines, corporate culture, organizational procedures, as well as strategic alliance Technological knowledge includes knowledge related to the access, use and innovation of production techniques and technology (Xu et al., 2005a,b) The relational knowledge consists of the potential derived from the intangible resources related to marketplace, such as brands, customer loyalty, long-term customer relationship, distribution channels, etc (Kanjanasanpetch and Igel, 2003) The knowledge management process architecture defines a variety of processes involved in the life cycle of knowledge, from its creation to termination Knowledge creation process, knowledge maintenance process, knowledge distribution process and knowledge review and revision process are the four steps in the entire knowledge management process (Bhatt et al., 2005) Creativity refers to the ability to originate novel and useful ideas and solution (Marakas, 2003) An organization creates knowledge through its employees who are equipped with knowledge and generate new ideas by breaking down business thinking that is no longer viable (Argyris and Schon, 1996; Lynn et al., 1996) Knowledge maintenance refers to making use of existing ‘discovered’ knowledge (Bhatt et al., 2005) Knowledge distribution means the sharing of knowledge across the organization Knowledge Syst Res 23,177^190 (2006) Jiayin Qi et al Syst Res RESEARCH PAPER review and revision is the modification and version management of knowledge The organization architecture

System The four elements in knowledge management system are interrelated to each other Knowledge management system can not attain its purpose without any one of the elements The knowledge architecture is the base of the knowledge management process The knowledge management process consists of the main activities in knowledge management The organization architecture is responsible for performing or supporting knowledge management process IT architecture is a facilitator for enhancing dynamic capabilities through knowledge management (Sher and Lee, 2004) Structure of Knowledge Management System According to the interaction among the elements in knowledge management system, the structure of knowledge management system is shown in Figure Both theoretical and empirical researches have shown that knowledge management can play a key role in creating sustainable competitive advantages for corporations In which, the organization architecture is the guarantee of knowledge architecture, knowledge management process architecture and IT architecture Right organization architecture has positive effects on the other three elements On the other hand, knowledge architecture, knowledge management process, and IT architecture all have impacts on organization architecture Organization architecture has to be adapted to meet the needs from the three elements too Knowledge architecture is the base of knowledge management process The fundamental function of the knowledge management system is to improve the business process and to achieve superior business performance through effective knowledge management process Enterprise Information Systems and Knowledge Management Enterprise information system (EIS) is an integrated information system seeking to integrate every single

resource, manufacturing, logistics, customer relationship management, etc An enterprise can get its EIS solution through integrating a number of modules Each module is business process-specific The use of EIS is associated with business process reengineering to optimize business processes An EIS creates an enterprise-wide transaction structure by integrating modules, data storing/ retrieving processes, and management and analysis functionality An EIS is not just a software system; it represents a new kind of managerial thinking A successful implementation of ERP is not only related to software selection, but also enterprise strategy, enterprise culture, business process reengineering (BPR), top management support, training and others Considering the relationship between knowledge architecture, knowledge process architecture, organization architecture, IT architecture, and enterprise operations, an EIS supports knowledge management that encompasses all types of knowledge in business operations The support provided by an EIS to an enterprise’ knowledge management is embodied in each module for specific knowledge management Each module associates with a specific type of business process, which corresponds to a specific knowledge management The knowledge management of the entire enterprise is realized through the integration of individual knowledge management module OVERVIEW OF OSS Evolution of OSS In the 1980s, the basic standard of OSS was determined The main usage is to manage networks In the beginning of 1990s, OSS standard has placed emphasis on both network systems and network management A substantial amount of work has been completed by the International Copyright ß 2006 John Wiley & Sons, Ltd 182 Syst Res Telecommunications Union (ITU) and the International Organization for Standardization (ISO) The representative standards of OSS are Telecommunications Management Network (TMN) and Simple Network Management Protocol (SNMP) In recent years, the next generation network (NGN) is coming ever closer NGN is a high speed multi-service packet data network capable of supporting the traditional functions of voice networks, data networks/internets and even mobility by providing quality-assured transmission, switching and services over IP and ATM cores The competitiveness is in managing service, not managing network resources Thus the OSS has shifted from network-oriented to service-oriented During the process of developing OSS standards, support has been provided by service providers (SP), network operation providers, equipment manufacturing enterprises, and software suppliers Definition of OSS OSS stands for Operations Support Systems OSS is a common term for the collection of all the support systems required to run a telecom operator’s business OSS is consisted of four subsystems: Operation Support System (OSS), Business Support System (BSS), Resource Support System (RSS), and System Support System (SSS) The functions of OSS consist of activation, inventory management, fault management, and workforce management, etc BSS includes customer care, multi-service provisioning, service assurance, and billing, etc RSS handles network resource management, operation information management, customer basic information management and customer service information, etc SSS deals with log file, system parameters, etc Figure provides a framework of OSS in which OSS and BSS are the main functions The main functions of OSS include, * * Customer care: provide an interface to the customers for all issues related to customer order, sales, billing, and problem handling Multi-service provision: activate instances of service for particular customers Syst Res 23,177^190 (2006) Jiayin Qi et al Syst Res RESEARCH PAPER

internal applications Activation: execute a service in an optimal and well-defined order Syst Res 23,177^190 (2006) 183 RESEARCH PAPER * * * Inventory management: keep track of the equipment such as where it is, how it is configured, and its status Fault management: handle alarms Workforce management: manage and schedule teams of technicians, installers and engineers In this paper, a network operator is defined as a telecommunication service provider with a network infrastructure and provides multiple services It could be a network, a fixed-line access network of any kind, or a mobile 2/2.5/3G mobile network This type of network operator is named as telecom operator throughout the paper Of course, the research is related to Service Provider (SP) and Content Provider (CP) with no infrastructure of their own although their tasks are simpler since they only manage services and IT infrastructure TOM and OSS OSS is intended to cover TOM (Telecom Operations Map) provided by the organization TMForum TOM model focuses on the operational processes within the telecommunication industry It was designed as a blueprint for process direction and a starting point for developing and integrating OSS The relationship between TOM and OSS is shown in Figure FAB (fulfilment, assurance and billing) is the core area of operations for telecom operators FAB defines the process for fulfilling an order, assuring the defined level of performance and facilitating billing for the services provided FAB is carried out through the following vertical processes: Customer interface management process: It is responsible for the dialogue with customer Customer care process: It deals with the customer needs, ways to identify the needs and how to achieve it Service/product development and operation process: It handles how the service is offered and how to achieve it Network and systems management process: It handles resources required for achieving the service offered to the customer Copyright ß 2006 John Wiley & Sons, Ltd 184 Syst Res Features of OSS OSS is a kind of EIS, which is applied to telecommunications industry Corresponding to the characteristics of EIS, OSS’ characteristics can be described as, The key idea of OSS is the modularization of telecommunications operation management Telecom operators face a lot of uncertainty The appearance of new services is very quick The modular design of OSS is considered a necessity (Wade, 2000) OSS realizes the end-to-end customer business operation processes TOM is an important reference function model for OSS planning The TOM model contains a detailed description of the most important processes involved in running a telecom operator’s operation Service fulfilment, service assurance, and billing are the three basic customer business operation processes OSS implementation will inevitably consider business process reengineering (Wade, 2000; Huang et al., 2003) OSS is a highly integrated software architecture Integrating multi-sections’ businesses in a single software platform efficiently for improving customer service is one of the aims of OSS This task requires a high level of integration among each subsystem OSS is not just a software system, but also represents managerial thinking Using TOM as an important reference model, OSS encourages telecom operators pay more attention to the customers rather than just billing as in the past (Walsh, 1998) Generally speaking, OSS can work not only for telecom operators, but also for those other enterprises with characteristics resemble to that of telecom operators with special network resources, special service flow, and value chain based on these network resources and service flows; for example, large power plants (Feng et al., 2001), traffic management (Takahashi, 1998), and others (Miyamoto et al., 1997; Sherif and Ho, 2000) Objectives of OSS As for the motivation for OSS’ implementation, there are six main reasons (Schroter, 1998): Syst Res 23,177^190 (2006) Jiayin Qi et al Syst Res RESEARCH PAPER Customer TOM Customer Interface Management process Invoicing Collection Customer Qos Management Problem Handling Order

TOM and OSS level improvement (Giannelli et al., 1990); (6) efficient network resource and customer resource management (Appel and Polosky, 1988; Kittel et al., 2000) The objective of OSS is to achieve superior performance, which is embodied in higher Syst Res 23,177^190 (2006) 185 RESEARCH PAPER average revenue per user (ARPU), better services, higher customer satisfaction, and improved asset utilization, etc KNOWLEDGE MANAGEMENT IN OSS Business Environment in Telecommunications Industry The telecommunications environment can be characterized by its inherent distributive, continuous expansion in the size of network, and the particular importance of fault-tolerance requirement These characteristics are reflected in the design of software systems Software systems in telecommunications have to cope with the universe of telecommunications protocols, numerous hardware platforms, and network architec´ tures (Cselenyi et al., 1998) The characteristics of telecommunications software systems include high software cost, concurrency, distributivity, reliability, diversity and complexity (Patel, 2002) Except the above-mentioned industry characteristics, telecom operators are facing more and more challenges nowadays Factors such as globalization and technology innovation represent radical challenges to telecom operators They must be more and more competitive to survive Today’s telecommunication market introduces more competitions; meanwhile offers more choices for customers, lower price and the pressure to improve service quality for operators As the previous monopoly situation is no longer exist, new entrants come into the market In emerging economy, state-owned operators are fully or partially privatized in order to survive better (Stienstra et al., 2004) Globalization promotes the domestic competition Global telecommunication market gives opportunities to some operators because of the economies of scale in telecommunication network, such as BT and Vodafone It also brings radical domestic competition since more new entrants enter to the market Internet technology causes an extraordinary growth of the Internet and IP services and applications Customers are increasingly free to choose different service components from Copyright ß 2006 John Wiley & Sons, Ltd 186 Syst Res different vendors and assemble their own solution (Li and Whalley 2004) Industry deregulation, globalization, and IP make the telecommunication industry full of intensified competition The telecommunication market involves a shift from a stable market to an increasingly user-driven market place The success of a telecom operator will entirely depend on the operator’s ability to create services and applications that are embraced by the users Same as the success brought by knowledge management to the manufacturing sector, knowledge management is increasingly helping the telecomm sector to keep sustainable competitiveness and competency Knowledge Management in BSS BSS focuses on developing the core business by defining marketing and offering strategies, new products implementation and managing existing products Customer interface management process and customer care process are the two major aspects involved in BSS Dialogue carrying, service ordering, service activation, trouble administration, and billing account review make up all the activities in BSS Staff knowledge, organizational knowledge, and relational knowledge form the knowledge architecture of BSS There is a plenty of staff knowledge involved such as sales staff’s experience There are also rich organizational knowledge existing in the customer interface management process and customer care process Deeper customer knowledge can give rise carriers an edge in developing pricing models (Limbach, 2004) In addition, relational knowledge exists in BSS such as reputation, brands, customer loyalty and distribution channel knowledge Those are the important factors influencing CRM Successful sales experiences can be acquired and shared among the employees in the sales and marketing department Replication, imitation, elicitation and innovation will be the main activities for knowledge creation Some knowledge on routine problems, success experience, standard business process, can be considered as existing ‘discovered’ knowledge to be maintained and reused Sharing of existing knowledge distributes Syst Res 23,177^190 (2006) Jiayin Qi et al Syst Res knowledge at the organizational level Due to the fact that the telecommunications industry changes rapidly, new services, new regulation policies, new market environments, all require continual revision of existing knowledge BSS is at the front-end in serving customers for telecom operators Due to the competition in telecommunications industry, organizational structures have increasingly been adjusted to customer-oriented All of these request organizational knowledge process Telephone call centre, interactive voice response (IVR), computer telephone integration (CTI), predictive dialers, wireless agents, e-mail, web self service, text chat and web collaboration make up the technology to complete customer communication IP based call centre, operational CRM and interactive CRM, billing system, and performance management are sets of software to support the business operation process The integration of these technologies and sets of software forms the IT architecture of BSS RESEARCH PAPER strategy, some intangible resources will inevitably be used And a successful strategy will also create new intangible resources These intangible resources are relational knowledge Knowledge can be created from studying previous successful service offering The enlightening effect can create new types of human, organizational, technological and relational knowledge All of the knowledge can be acquired and reused Sharing such knowledge can further diffuse knowledge across the enterprise OSS is operated at the back end which provides decision support for BSS Knowledge sharing and creating are essential to such decision support function For reducing ‘noise’ and eliminating barriers across sectors, smooth communication is required Organizational structure, based on traditional command and control, must shift to an open and collaborative structure The analytical CRM is an outstanding component to support service/product development process Decision support system (DSS) and expert system (ES) are both common tools Knowledge Management in OSS Knowledge Management in RSS OSS focuses on planning, developing and delivering services and products in operation domain Service/product development and operation process are the operational processes OSS deals with service generation and network resource planning Human knowledge, organizational knowledge, technological knowledge and relational knowledge are all involved in OSS Those previous service cases, as well as proven cross-selling rules are human knowledge How to organize service/ product development, operation process, and network, is considered as organizational knowledge In addition, culture, regulations, and partnerships are considered as organizational knowledge as well There are many innovative techniques and skills involved with these which are considered as technological knowledge Interestingly, the greater the scope of services offered, and the greater the range of quality and price options, the more efficient (and cost efficient) the use of the network resources Service innovation is a key factor for revenue growth of a telecom company For designing a successful marketing Copyright ß 2006 John Wiley & Sons, Ltd

applications that interact with each other to enable support, administration and management of services for telecom industry It includes systems that manage the networking infrastructure, planning tools, billing systems, customer care, trouble management tools and the like It is the fundamental integrated software platform for telecom operators It is an EIS used in the telecommunications
