  • 12. Preface Traditional availability management focuses on managing the state of IT resources at a component level, without the context of the required service necessary to support vital business functions. As IT organizations mature and focus more on meeting business objectives, they recognize the value of providing sustained levels of availability. They also improve service quality that is consistent with business objectives and cost constraints. Managing IT costs requires repeatable and measurable processes such as the best practices for service level management (SLM) documented in the IT Infrastructure Library (ITIL). Central to the ITIL best practices are the service management processes. These are subdivided into the core areas of service support (day-to-day operation and support) and service delivery (long-term planning and improvement). This IBM® Redbook takes a top-down approach that starts from the business requirement to improve service management. This includes the need to align IT services with the needs of the business, to improve the quality of the IT services delivered, and to reduce the long-term cost of service provision. It focuses on how clients accomplish this by implementing SLM processes supported by IBM Tivoli Service Level Advisor and IBM Tivoli Business Systems Manager. The approach used in this book leverages Tivoli® and non-Tivoli monitoring sources. IBM Tivoli Monitoring for Transaction Performance, IBM Tivoli Monitoring, and various IBM Tivoli Monitoring PACS, along with Peregrine ServiceCenter, serve as interface points to provide the end-user perspective of service delivery. For IT managers and technical staff who are responsible for providing services to their customers, use this IBM Redbook as a practical guide to SLM with IBM Tivoli products. It takes you from a general outline of SLM to specific implementation examples of banking and trading that incorporate the Tivoli monitoring products. The key elements that are addressed in this redbook are: Organizational considerations for implementing the ITIL processes Identifying which services or business functions will be used for the initial deployment Determining the metrics and monitoring sources required for operational and service level agreements (SLA) definition and evaluation, including business schedules and maintenance periods© Copyright IBM Corp. 2004.

  • 21. 1.1 Service level management overview The goal of maximizing profits drives change as well as innovation. It often involves the use of IT to gain a competitive advantage in selling a company’s products and services. To achieve their goals, business units partner with an IT organization to implement technology projects and thus become IT customers. Accordingly, IT organizations are hired by business units to provide technology services. Therefore, they must meet their requirements for those services. In today’s cost-conscious environment, IT organizations are under pressure to reduce costs even as they must deliver a higher level of service to increasingly well informed users. Why service level management? For this reason, customer perception of the availability and performance of these services drives customer satisfaction. As a service provider, an IT organization must be able to demonstrate and guarantee quality of service to its customers. However, IT management has often struggled to measure delivered services while reconciling such measurements with the perceived quality of this delivery. To solve this problem, IT organizations are deploying SLM that includes contracts between IT and its clients that specify the client expectations, IT’s responsibilities, and the compensation that IT will provide if the goals are not met. The main factors for driving interest to SLM are: Complexity: A dramatic increase in the number of applications, their importance, and demand on IT infrastructure Dissatisfaction: Increasing user sophistication and growing dissatisfaction among users with service that they receive from IT Better technology: More mature technology that can provide end-to-end measurement, reporting, and management at a reasonable cost and offer more simple process What is service level management? SLM is a means for the lines of business (LOB) and IT organization to explicitly set their mutual expectations for the content and extent of IT services. It also allows them to determine in advance the steps to take if these conditions are not met. The concept and application of SLM allows IT organizations to provide a business-oriented, enterprise-wide service by varying the type, cost, and level of service for the individual LOB.4 Service Level Management
  • 22. According to the highly popular, process-based methodology IT InfrastructureLibrary (ITIL), SLM is the process of negotiating, documenting, agreeing andreviewing business service requirements and targets, within service levelrequirements and agreements between service providers and their customers.These relate to the measurement, monitoring, reporting, reviewing, andcontinuous improvement of service quality as delivered by the IT organization tothe business.ITIL’s methodology provides two models for IT activities: service delivery andservice support.Service deliverySLM, along with availability management, capacity management, IT servicecontinuity management, and financial management for IT services, comprisesthe service delivery model. The primary role of this model is to offer a proactiveprocess of planning and management of service according to the plan.Service supportThe service support model includes incident management, problemmanagement, change management, release management, and configurationmanagement. The primary role of this model is to offer operationalimplementation and monitoring of service according to the plan.Figure 1-1 shows how the service delivery and service support models fit in theITIL roadmap for service management.

  • 23. According to the ITIL, SLM relates to the other aforementioned disciplines as follows: Supported by availability management, IT service continuity management, capacity management, problem management, and configuration management Provides information to incident management and change management Monitored via financial management for IT services, incident management, capacity management, and availability management Supports application management, business processes, and event management SLM is the disciplined, proactive methodology. Procedures are used to ensure that adequate levels of service are delivered to all IT users in accordance with business priorities and at an acceptable cost. Service levels typically are defined in terms of availability, responsiveness, integrity, and security delivered to users of the service. Pros and cons of service level management Although the duration and scale of SLM implementations may vary, both large and small corporations can capitalize on the benefits of SLM. They do so by choosing the components that are most appropriate to their specific SLM needs. Implementing SLM requires time and effort. It is difficult to rationalize allocation of IT resources to this project if IT is already working with limited resources. In addition, IT clients sometimes abuse the SLM processes, especially when they aim for unreasonable or unattainable service level commitments. However, this should not stop IT management from developing SLM, which can be equally important for both business units and an IT organization. SLM increases the efficiency of an IT organization and introduces a financial incentive and penalty system for service delivery. Indeed, the rising popularity of SLM testifies to its value. For an IT organization, the effective SLM is often a matter of survival particularly if its mission is to operate as a business. The product of an IT organization is the service it delivers to business units. For an IT organization, providing quality services is not enough. The service must consistently be of the same high quality both in actual delivery and in the eyes of the users of the services. SLM supports IT organizations to improve the quality of the services provided and the quality of the services as it is perceived by the users of IT services. Refer to Appendix A, “Service management and the6 Service Level Management
  • 24. ITIL” on page 447, for a definition of quality of services and how it is perceived by users and customers of IT services. Both an IT organization, as a seller, and a business unit, as a buyer, need a contract that clearly defines both the capabilities and limitations of this process. For reasons of customer satisfaction and cost control, the product must meet the specifications of this contract.1.2 Service level management benefits Businesses need to respond quickly to market demands and seek to maximize profits. These goals often result in a high volume of change for IT organizations. Every IT organization has an objective to align its goals with business requirements and to better support business needs. They use SLM to ensure that scarce IT resources are prioritized to focus on key business requirements. By implementing SLM, IT organization can achieve many of their goals. However, they must overcome many challenges to ensure that the SLM program is successful. Goals The goals of SLM are: Understand and meet the requirements of customers and end users Use resources efficiently, effectively, and provide value for money Improve continuously through a process of learning and growth Use internal process to generate added value for customers and survive Establish a business-like relationships between the customer and supplier Challenges The challenges of SLM are: Divergent views of business and IT organizations Diversity of organization business areas Changing the mind set from products and systems to services Perception of IT (historically not always good) Unknown components, dependencies, and ownership Poor quality management information and metrics Unable to justify investment or assess risk No measure of proof of improvement Coping with infrastructure complexity Providing consistent and stable services Chapter 1.

  • 25. Faced with many constraints, an IT organization wants recognition for providing good services based on component-centric measurement metrics. At the same time, business units feel that they are paying for a service, but cannot perform their work and do not trust IT that always report good service. SLM offers evolution for measuring IT effectiveness by moving from the component-based evaluation of service to service-based management. Figure 1-2 illustrates a situation where the reduction of the downtime of components reported by the IT organization does not improve customer satisfaction because the damage has already been done. It emphasizes the fact that business units and IT organizations have different views of the customer perception on the quality of the services provided.

  • 26. How can SLM help IT to deploy resource fairly? Client satisfaction SLM necessitates IT management to initiate a dialog with business units to understand the requirements for service. It also forces business units to clearly state their requirements and expectations. Improved client satisfaction is the main benefit of SLM, which ensures it through negotiated SLAs, established benchmarks for service measurement, and continuing dialog through reporting and reviews. Managing expectations SLM makes it possible to avoid an expectation creep of rising levels of IT clients’ undocumented expectations. Undocumented users’ requirements and expectations levels usually lead to expectations staying ahead of service that is being delivered. SLAs document negotiated requirements and establish expectations. They also serve as brakes when users want higher levels of service than IT committed to deliver. Resource regulations SLM provides a mechanism for governing IT resources. It allows IT to reject demands for resources to applications that unfairly tie up resources, and therefore, regulate workload based on business priorities. SLM helps to avoid capacity problems by providing early warning of SLAs being violated. Additional equipment might be required to support IT commitments. Cost control SLM helps IT to determine, through dialog with users, the level of service required and to determine the acceptable capacity and staffing it needs to provide. SLM can demonstrate that desirable service is not always affordable and can impact costs through moderating user demands for higher levels of service. It allows IT to explain the financial impact of higher levels of service and avoid the unnecessary cost by forcing users to justify the additional cost.SLM helps to change relationships between business units and IT from anegative acceptance of IT as a necessary evil to viewing IT as an asset inexecuting their mission. When the clear service objectives are documented andnegotiated measurement reporting is in place, IT has the means to manage itsresources as well as user dissatisfaction.BenefitsIn summary, the benefits of SLM are: IT service designed to meet agreed requirements Clearly defined roles (activities, responsibilities, and authority) Measurable, realistic SLAs for improved customer and supplier relationships Balances service requirements against the costs Chapter 1.

Reduces risk of unpredictable demand and capacity problems Helps identify service weaknesses Allows underpinning of supplier management Provides basis for charging and measuring value Establishes an improvement baseline1.3 Service level management components To create and maintain SLM, IT managers need well defined processes, proven tools, a dedicated effort, and a business wide commitment. SLM shifts IT management perspective away from technology and toward the demands of the business and user experiences. It introduces new methods and procedures as well as makes enhancements to the old ones. SLM focuses on the management of an IT service in support of a specific business process. An IT service includes applications and infrastructure resources used by this business process. Management includes planning, monitoring, and reporting. SLM uses SLAs to identify service and determine its management criteria. SLM is a process that is supported by several other processes, including performance and availability management. Both performance and availability management processes are essential for monitoring SLAs. However, an understanding of end-user perspectives through synthetic transactions and communications with users is also critical. Accordingly, monitoring of performance and availability must be adjusted to account for user experiences. For this reason, IT operations must incorporate end-user experiences and business function knowledge into the management IT infrastructure and applications. In addition, IT support must incorporate business requirements into the asset management, change management, and incident management. The following sections introduce four SLM components that are essential for implementing a successful SLM program. Processes Documentation People Tools10 Service Level Management
  • 28. 1.3.1 Processes The functions in SLM can be divided as follows: Identify users’ expectations and define parameters for service. Ideally, IT must identify all of the business processes that must be managed. In practice, it is acceptable to select the critical business processes during the first stages of the SLM process implementation and then incorporate additional business processes as the SLM process mature. The IT organization can work with business owners to pinpoint the elements of these business processes. They can define service parameters such as end-user expectations of service, participating IT application and infrastructure components, and metrics for measuring service levels. Assess service capabilities and negotiate service agreements. First an IT organization must have a clear understanding of service expectations, composition of service elements, and service level measurement metrics. Then it must collect data and assess its current capabilities for meeting a customer’s expectation of service levels. After studying current capabilities for delivering all services required and indentifying opportunities for improvement, IT management is ready to talk with customers about the service levels that it can provide. IT should avoid technical terminology and describe services and expectations in a manner that is understandable to its customers. At the same time, IT should fully understand what service levels it can deliver and achieve agreement from its customers on service levels measurement and reporting criteria. IT must document negotiated expectations and measurements metrics as well as agreed upon acceptable service levels values. Manage to meet service level objectives (SLOs). IT must align its processes to proactively monitor, measure, and manage against negotiated SLAs. Accordingly, IT must develop SLOs to meet SLA obligations for underlying IT components, measure actual values against SLOs, and associate the measured status against the SLAs. Upon recognition of service level degradation (preferably through real-time alerts), IT can immediately start finding a problem and restoring service to acceptable levels as defined by SLAs. If the problem is serious, IT may also notify users so they can avoid affected services and calls to the help desk. SLAs that relate to IT operations and support (OLAs) recognize component issues quickly and evaluate their measurements prior to their impact on SLAs and IT customers. IT must come up with monitoring processes, measurement metrics, and automation that allow prompt responses to problems by technical staff in addition to reporting an OLA’s status to management.

Effective reporting should show IT performance against service-level commitments (successes and failures). It can be used together with financial incentives to improve IT processes and users behavior. Continue service refinement and improvement. The SLM process should always be examined for process effectiveness, service changes, and reporting accuracy. Customer expectations change as business processes grow and new applications and users are added. As monitoring technology improves, IT can expand metrics that measure component performance and customer satisfaction. IT must periodically re-evaluate the services it provides. Service improvement is a continuous process that allows IT to add more value, adjust to new realities, justify new technology, and often derive more revenue. The same can be said about the SLM process that needs continuous improvement to gain the trust of business owners, improve efficiency through automation, and effectiveness through a better understanding of business-to-IT relationships.

  • 30. 1.3.2 Documentation Because SLM relies on several parties involved in defining the processes, negotiations, penalties, and so on, documentation is a must. The following documents support SLM: Service level agreements An SLA is an agreement between business units (the customer) and IT organization (the service provider). It describes the service and service level measurement metrics, defines the approval and reporting process, and identifies the primary users. It can also include financial terms and conditions. SLAs provide a mechanism for establishing accountability for both IT and their customers for the provided service levels which are negotiated and agreed to based upon business requirements, priority, and cost. SLA measurements must be directly aligned with customer expectations. SLAs are the basis for service level evaluation and improvement processes that include periodic reviews and adjustments if needed. Operational level agreements An operational level agreement (OLA) is an internal agreement that shout be established between all business and IT groups prior to the execution of an SLA. The OLA establishes specific requirements that each IT group needs to meet in support of service levels and make them accountable for their contribution to the overall improvement of service levels. Well-defined OLAs show IT management which areas have more impact on service levels, where to focus attention and financial rewards, and how each group can contribute if business requirements require a change of SLAs. Underpinning contract IT should establish underpinning contracts (UCs) for any service provided by external service providers and vendors. UCs add accountability for external component of service levels in the same way as OLAs account for the internal components of service levels. IT can use the contractual agreements that they have with their third-party vendors and feed the pertinent data into the SLM process. As service levels need to be changed, IT may need to re-negotiate external contracts with vendors and modify the UCs. Figure 1-4 illustrates the flow of customer, internal, and external contracts. Service catalog The service catalog provides a place to document all services provided to the customers and to record such details as key features, components, charges, and dependencies for each service.

They include one or more service level indicators (SLIs) presented in the business context. The SLO defines the component of service and how it is being measured. SLIs determine measurement metrics for SLM quantification. SLIs should reflect user perspective such as pain points and priorities, service availability, and responsiveness. For example, the most common SLOs are availability and performance. A service availability SLO may include the SLI measured in the percentage of time that the service was in available state. A performance SLO may include two SLIs: service responsiveness (response time) and completed work (number of transactions). An IT organization must use monitoring for measuring the actual results of SLIs and reporting for communicating these results to business and IT managers. The format, details, and period vary depending on the recipients of reports. SLM can also include real-time information, alerting IT when results approach or breach service levels are guaranteed by SLAs.14 Service Level Management
  • 32. Service improvement program SLM is a continuous process that includes service level improvement and SLM improvement activities. IT should never be satisfied with current level of service even if it satisfies its obligations to customers. IT should develop a service improvement program and document a service quality plan. This plan should include how to maintain awareness of changing business objectives, cost-effectively add new technology, improve daily operations, and expand SLIs and reporting to match user perception of service as much as possible.1.3.3 People The SLM process requires the involvement of people at various levels within business and IT organizations. The request for service improvements often starts with the head of a business unit or a senior executive who begins demanding more consistent service and accountability from IT. IT management may respond with tactical improvements but may be forced to implement the SLM program. SLM is a collaborative effort. Its implementation includes a number of people in dedicated or supporting roles. Responsibility for overall management of the SLM program is most likely to be assigned to a senior IT executive. IT may also assign a dedicated project manager and a dedicated service level manager. The project manager is responsible for implementing the SLM project. A service level manager is active throughout the entire implementation phase as well as after the phase. This person also coordinates ongoing management and improvement programs. In their effort, both the project manager and the service level manager need support from line managers of IT and business groups. The SLM team must include representatives from both business units and IT service delivery and may require some assistance from consultants. However, SLM is primarily an IT effort as it is IT who must handle the technical aspects of the SLM implementation, deployment, and operation. The SLM program must have an executive sponsor who provides funding for the program and is ultimately responsible for the success of the SLM program. For more details about the roles and responsibilities of the people involved in implementing SLM, see 2.2.1, “Identifying roles and responsibilities” on page 26.1.3.4 Tools While developing the SLM plan, the IT organization must choose tools to enable the SLM process that is being developed. Depending on the selected measurement metrics and the service composition of related IT resources, these Chapter 1. Introduction to service level management 15
  • 33. tools support monitoring of the chosen service indicators and user experiences. They also provide analytical capabilities and aggregation for reporting. In addition, IT must organize the collected data and make it accessible to everybody with a stake in the SLM process. Analytics and reporting must present this data in a manner that aligns the service views of both IT and their customers, allowing them to reconcile the customers’ perception of service with the service levels delivered by IT. IT wants to understand how resource performance and availability affects service levels and what adjustments are needed to improve service. Customers want to make sure that IT delivers availability and responsiveness to the critical applications that they use for automating their business processes. When their business process is impacted, they want IT to accurately report it so they can impose the negotiated penalties on IT. SLM is a hot topic, and many companies have made claims that their products provide SLM solutions. Some products are specifically designed for SLM. Others offer only aspects of monitoring capabilities but still market their products as SLM solutions. When implementing SLM, IT should choose the following tools to meet their design specifications: Monitoring tools to provide the measurement metrics they need to collect Reporting tools that process the data being captured and satisfy all levels of report recipients Analytical tools that provide aggregation and analysis of the collected SLM data in a manner that offers fast recognition of business impact and proactive response Administration tools that improve the productivity of SLM operators and users as well as provide the integration of monitoring, reporting, and analytical tools This book introduces solutions provided by IBM, which include a wide range of products that can monitor a variety of distributed and mainframe servers, databases, transactions, networks, Web servers and end-user experiences. In addition, IBM offers analytical products in SLM space that provide the real-time integrated event console, event correlation, business service management (BSM), and proactive SLM. All these products accept data from the majority of today’s monitoring products.16 Service Level Management
  • 34. 1.4 Business service management approach to servicelevel management The philosophy of managing services in a business context is receiving more traction with IT organizations that are trying to improve relations with their customers. These same organization are also trying to overcome historical challenges such as customer perception and the increasing complexity of technology. Understanding how shared infrastructure resources are being used by business processes significantly improves the ability of business and IT executives to negotiate, measure, and evaluate service contracts. Many IT organizations are turning to BSM solutions to facilitate a business-defined view of IT-delivered services. BSM solutions provide facilities and analytics that enable IT to manage service levels with the business consumer for a specific business process to ensure that the SLA associated with this process is fulfilled. Why business service management? Earlier this chapter introduced SLM as the management of IT resources to deliver the required service at the required level of quality. BSM allows IT to incorporate business knowledge into the service management process and to translate data from traditional infrastructure and application management tools into business-level representations. BSM relies on IT organizations that work with business units to map resource-to-service relationships and organize them into structures that depict and visualize the components of IT infrastructure as well as automate components of the business process based on the knowledge of their relationships. Accordingly, with BSM, IT management and business executives can reconcile their perspective of IT performance. This is because BSM can report both real-time status and historical service-level compliance for each business function supported by IT. What is business service management? BSM is a service management application that aligns IT operations with business processes. Therefore, it allows business functions to receive maximum leverage from IT resource management. BSM solutions enable real-time management of events and service levels based on knowledge of their relationships to an IT service provided to a business entity responsible for a business process. BSM provides IT with a set of algorithms and visualizations that IT must incorporate in its SLM processes. It is designed to display and report the service Chapter 1. Introduction to service level management 17
  • 35. delivery health and business impact of IT based on performance and availability of IT resources. The visualization of BSM runs on federated event and monitoring data as well as business and IT relationship data. The four aspects of BSM are: It consists of identifying the components of a business system. It involves measuring the performance and availability of those components. It ensures that the components are performing within SLOs. It alerts to any deviation or potential deviation from SLOs. The concepts behind BSM include: Resources are components of IT infrastructure. Business transaction is a group of IT resources supporting a particular IT workload. Business system is a group of resources that supports a business goal. Business process is composed of some automated (IT services based) and some manual steps. When policy data or service level information is attached to a business system, it turns into an IT service. IT service can be perceived as a collection of IT resources that make up the automated part of the business process.1.4.1 Convergence of business service management and service levelmanagement With BSM, an IT organization gains insight into a business process. It can use this insight to design SLM based on the aforementioned relationship structures that we call business systems. A business system is a representation of a group of diverse but interdependent enterprise resources that are used to deliver specific business functionality. Business systems allow flexible and automated arrangements of IT resources into models of services that IT provides to automate business functions. Together, they represent what we call the Business/IT knowledge base that is an important element of the SLM methodology. As a result of a joint effort to develop the Business/IT knowledge base, an IT organization and business units have a framework for SLA that allows them to: Identify all components of a service Create SLA and OLA contracts based on business systems Measure resource performance and availability by business systems18 Service Level Management

Get service violation and trend alerts for any deviation or potential deviation from the SLO Ensure that services are performing within the SLO The Business/IT knowledge base provides the foundation for BSM and SLAs. In reality, BSM allows IT to decompose business processes into IT systems and document the negotiated service levels in SLAs to be managed by BSM via monitoring and analytics organized by business systems. BSM accepts data from a variety of performance and event data sources that monitor IT resources. The BSM analystics then consume this data to determine business systems status and understand its business impact. Figure 1-5 demonstrates that business systems are a cornerstone for establishing service levels and managing IT resources based on business objectives for IT services.

As outlined earlier, the BSM approach to SLM helps this effort by collecting business knowledge and exposing the use of resources by services. This makes SLA contracts and measurement metrics more meaningful to both IT and business units. Chapter 1. Introduction to service level management 19
  • 37. 1.5 Improving service level management throughintegration SLM is the continuous process of measuring, reporting, and improving the quality of agreed upon service that an IT organization provides to the business. This requires that an IT organization clearly understands each service it provides, its business importance and priority, who consumes this service and how, and the IT resources are used. Such information is usually dispersed and requires a significant effort from IT to obtain and organize it a meaningful way that can expose business use IT resources. As demonstrated earlier, you can use BSM to compose and refine services from related resource and business systems objects. Service compositions defined by BSM allow IT to design SLAs and service level measurement criteria in an integrated manner and provide: Improved effectiveness of SLAs When a IT organization uses the same definitions of services for aggregating monitored data, service management, and service evaluation, it can significantly improve the effectiveness of SLAs and make investigations of SLA violations more productive. Improved effectiveness of communication Through a set of federated monitoring data and views, IT can use service compositions to effectively communicate with users (while developing and reporting SLAs) and to prioritize management of incidents. Figure 1-6 presents a high-level view of integrating monitoring, service management, and service evaluation around service compositions. Management of IT resources within the context of the business services they provide includes: Automatic discovery of IT resources and their relationships Automation for constructing services and business systems Detections of incidents for IT resources in a service context Determination of service status and business impact of incidents Warehousing of historical data for IT resources and services Service level evaluation and alerting in service context Reporting service health and service level compliance with SLAs20 Service Level Management

BSM then integrates this databy supplying business analytics and automation that allow IT to define andmanage services throughout the life cycle of SLM.Armed with business knowledge and negotiated service composition andmeasurement metrics, an IT organization can design its business systemmanagement, SLM, and monitoring processes to measure quality of service thatcorrelates with user perception. To improve acceptance, IT must continue to Chapter 1. Introduction to service level management 21

One of the main objectives is to relate the definition of service to the perception of IT users and business unit management. The quality of services delivered to these users is judged according to users’ ability to use services effectively and cost-efficiently when required by their job functions. Although IT managers place a high priority on meeting this objective, the task of reporting on quality of service that users accept as matching their experiences is often hit and miss. The BSM approach (outlined earlier in this chapter) to SLM offers significant improvements in this area by making business to IT relationships more factual and transparent through several implementation steps. The topics in this book are structured to guide you through analysis of SLM and its planning aspects to detail implementation of BSM, SLM, and monitoring integration approach using Tivoli products. They include a summary of improvement opportunities for each topic. The remainder of this book is divided into the following chapters: Chapter 2, “General approach for implementing service level management” on page 23, describes a generic approach for SLM implementation, following the ITIL process improvement model as close as possible. Chapter 3, “IBM Tivoli products that assist in service level management” on page 53, provides an overview of the IBM Tivoli products that support SLM processes. Chapter 4, “Planning to implement service level management using Tivoli products” on page 109, outlines the planning and implementation of SLM and BSM through the integration of several IBM Tivoli products. Chapter 5, “Case study scenario: IRBTrade Company” on page 197, provides a test case of the SLM program implemented to manage the distributed environment for a trading company. Chapter 6, “Case study scenario: Greebas Bank” on page 315, provides a test case of the SLM implementation of enterprise management (mainframe and distributed) for a bank. Appendix A, “Service management and the ITIL” on page 447, discusses the various components and definitions behind Service Management in ITIL terms. It is designed as a reference for Anyone involved in the SLM process.22 Service Level Management
  • 40. 2 Chapter 2. General approach for implementing service level management Service level management (SLM) is an important initiative. It requires the participation and support of many resources. A successful implementation has an established business need, commitment from all those involved, and funding to ensure adequate resources and tools for completion. It requires a strategy and a flexible plan for negotiating, implementing, and maintaining service level agreements (SLAs). The typical motivation for SLM is the need to improve IT service delivery as perceived by customers. In many cases, the team responsible for IT service delivery does not have all the information required to meet the needs of the business. As a result, IT delivers and reports on top quality service, while business units experience service that is perceived to be of a low quality. SLM provides a means to overcome this challenge, providing the many benefits described in 1.2, “Service level management benefits” on page 7. Executive management commitment for SLM is essential since the goal of aligning IT and business requires an organization-wide commitment from both business and IT representatives. It takes hard work and discipline to implement SLM. Simply providing funding is not enough. Executive management can© Copyright IBM Corp. 2004. All rights reserved. 23

This chapter describes a generic approach (Figure 2-1) for implementing SLM after a decision to do so is established.

  • 42. Chapter 1, “Introduction to service level management” on page 3, introduces the four key components of SLM: people, processes, documentation and tools. This chapter identifies and discusses each of these components in more detail.2.1 A look at the ITIL process improvement model An organization may already have some elements of SLM established and operational. Therefore, the approach taken in this chapter to present a method for SLM implementation is one of process improvement. This chapter applies the ITIL process improvement model to an SLM implementation. ITIL process improvement model is summarized by asking the following questions in the order presented: 1. Where do we want to be? This question provides the vision and objectives for an SLM implementation. It is answered by having a clear definition of provided services, determining the current perception of quality of the services being provided, and defining the desired quality of the services to be provided to customers. These topics are addressed in 2.2, “Planning for service level management implementation” on page 26. 2. Where are we now? Perform a thorough assessment of the existing IT infrastructure’s ability to deliver the defined services, and its existing monitoring capabilities. After this task is completed, perform a gap analysis of both the IT infrastructure and the monitoring capabilities so that IT can deliver services with the expected level of quality required by the business and expected by the customers. These topics are also addressed in 2.2, “Planning for service level management implementation” on page 26. 3. How do we get where we want to be? Based on the information gathered from the previous two questions, an IT organization prepares service level objectives (SLOs), constructs SLAs, and negotiates them with customers. This is also the time when additional IT infrastructure, monitoring tools, or both should be put in place. Most importantly, adjustments to existing IT processes to accommodate SLM are performed. These topics are addressed in 2.3, “Implementing service level management” on page 35. 4. How do we know we have arrived? When the implementation is complete, hold review sessions to ensure that all specified goals were met. Also discuss how to resolve unmet goals.

These topics are also addressed in 2.3, “Implementing service level management” on page 35.2.2 Planning for service level managementimplementation This section describes the planning activities that lead to a successful SLM implementation. The desired output items of this phase are: A carefully chosen team capable and committed to implementing SLM This team should include the project manager and service level manager roles to keep deployment participants on track and communicating regularly. A thorough understanding of the services to be managed To accomplish this, collect information from both the business and technical perspectives and then have the service level manager mediate it. Business owners provide an overview of the major functions and an understanding of user demand. The IT service delivery organization provides detailed information about the components that make up the services that support the business functions. Identify current perception of the quality of the identified services and the desired quality level of those services. An assessment of the ability to deliver services based on the expected level of quality This includes an understanding of the current capabilities of the IT infrastructure to deliver services to the quality expected by the business owners. Consider users’ current perception of service levels in this assessment. Based on this assessment, improvements to the IT infrastructure may be required.
