The service definition for proactive secondary goals defines how the organization provides proactive support, including the identification of network down, link-down or device-down conditions, network error conditions, and network capacity thresholds. Measurable reactive support goals include: Measure reactive support goals by generating reports from help desk databases, including the following fields: The time a call was initially reported (or entered into the database), The time the call was accepted by an individual working on the problem. This generally creates gaps in proactive support management capabilities and results in additional availability risk. We took one of the world’s most popular help desk software... BMC Exchange 2020: Build Your Own Chatbot, The Incident Commander (IC) Role Explained, Impact, Urgency & Priority: Understanding the Matrix. See the following examples of SLA requirements for specific business needs. To accommodate for this, the organization should measure the service standards and measure the service parameters used to support the service standards. Another service indicator may be that the organization states service or support satisfaction as a corporate goal. See the following table: So far, the service level definitions have focused on how the operations support organization reacts to problems after they are identified. Then hold monthly meetings between user and support groups to review the measurements, identify problem root causes, and propose solutions to meet or exceed the service level requirement. This may be higher in other environments because of the number of redundant devices in the network where switchover is a potential. To define the support process, it helps to define the goals of each support tier in the organization and their roles and responsibilities. Implementing service-level management consists of sixteen steps divided into the following two main categories: Network managers need to define the major rules by which the network is supported, managed, and measured. This value is typically called "system switchover time" and is a factor of the self-healing protocol capabilities within the system. The group effectively moved from reactive to proactive in nature and helped the bottom line of the company. This allows the organization to properly evaluate vendors, carriers, processes, and staff. If the organization currently measures availability, you may not need an availability budget. Download Now: ITIL Best Practice e-Books. These requirements are generally availability, QoS, performance, and MTTR. Build a Clear Strategy. Set goals that promote proactive management because quality proactive management helps eliminate problems and helps fix problems faster. For the above availability definition, this is equal to the average amount of downtime for all connections in service within the network. Whenever an IT service is designed or changed, its accompanying SLA should also be reviewed and modified to make sure it is fair, enforceable, and realistic. When the organization does root-cause analysis on the issues and makes quality improvements, this then may be the best methodology to improve availability, performance, and service quality available. To determine this, the organization needs to understand the MTBF of all network components and the MTTR for hardware problems for all devices in a path between two points. However, planners may want to assume a small amount of downtime due to broken or loose connectors. Add specific messages or issues to the service level definition if the need arises. Additional details include the following: Onsite support business hours and procedures for off-hours support, Priority definitions, including problem type, maximum time to begin work on the problem, maximum time to resolve the problem, and escalation procedures, Products or services to be supported, ranked in order of business criticality, Support for expertise expectations, performance-level expectations, status reporting, and user responsibilities for problem resolution, Geographic or business unit support-level issues and requirements, Problem management methodology and procedures (call-tracking system), Network error detection and service response, Network availability measurement and reporting, Network capacity and performance measurement and reporting. Ensure you create thresholds that are meaningful and useful in preventing network problems or availability issues. Additional days will be needed when a holiday falls within a delivery period. The well-constructed SLA then serves as a model for efficiency, quality, and synergy between the user community and support group by maintaining clear processes and procedures for network issues or problems. In some cases, the organization may have different service level goals within one area. The next step is identifying participants in the SLA working group, including a group leader. It will not be considered a service level miss if a new user request has been received but management is slow in approving the new user. For example, an organization might achieve 99 percent availability when the goal was much higher at 99.9 percent availability. For LAN networks, a conservative estimate is approximately 99.9999-percent availability, or about 30 seconds per year. 2) IT Service Management is NOT Only ITIL. The following table shows the performance targets within the United States. A network life-cycle assessment is available from Cisco NSA high-availability services (HAS) services showing current network availability constraints associated with network life-cycle practices. One method is to send Internet Control Message Protocol (ICMP) ping packets from a core location in the network to edges. SLA targets will be temporarily waived in the event of a. Managers and decision-makers who can agree on key SLA elements should participate. Service Level management performance indicators provide a mechanism to monitor and improve service levels as a measure of success. Company X was getting numerous user complaints that the network was frequently down for extended periods of time. are planned by the IT service provider. Documented service-level definition or SLA that includes availability, performance, reactive service response time, problem resolution goals, and problem escalation. This also helps focus network management tools/information on resolving problems proactively rather than helping with the root cause. Non-fulfillment consequences These days, many companies have found these external SLAs so useful, internal SLAs within or between departmentsare becoming ever more common. This may be easy to satisfy in a metropolitan area, where there are a lot of technicians. This is a very important area because un-checked device control plane resource issues can have serious network impact. In other cases, such as with VoIP, network requirements including jitter, delay, and bandwidth are well published and lab testing will not be needed. The organization does not use VoIP and does not wish to factor in software switchover time. When the organization is not meeting service goals, it should then look to service metrics to help understand the issue. Organizations with the latest software versions are expected to have higher non-availability. SLM (Service Level Management) or SLA Management processes provide a framework by which services are defined, service levels required to support business processes are agreed upon, Service Level Agreements (SLAs) and Operational Level Agreements (OLAs) are developed to satisfy the agreements, and costs of services are developed. This then helps distinguish between network problems and application or server problems. SLA Management Best Practices. Organizations that implement proactive service level definitions or agreements do so because of business requirements and potential availability risk. The gold service would have two routers, but backup Frame Relay would be used. The organization must also define a service that can quickly identify and resolve potential service issues that will impact availability and performance if ignored. One major factor of hardware reliability is the MTTR. The site would have two routers configured so that if any T1 or router failed the site would not experience an outage. SLAs must represent SMART goals—specific, measurable, achievable, relevant, and timely. Without this definition (or management support), the organization can expect variable support, unrealistic user expectations, and ultimately lower network availability. One goal of the network SLA should be agreement on one overall format that accommodates different service levels. When problem severity has been defined, define or investigate the support process to create service response definitions. Other service providers will concentrate on the technical aspects of improving availability by creating strong service level definitions that are measured and managed internally. Application profiling helps you better understand these issues; the next section covers this feature. Step 8: Determine the Parties Involved in the SLA, Step 10: Understand Customer Business Needs and Goals, Step 11: Define the SLA Required for Each Group, Step 14: Hold Workgroup Meetings and Draft the SLA, Step 16: Measure and Monitor SLA Conformance. The one caveat is that organizations need to understand the current risk to availability in their own processes and levels of expertise. Reactive service response time by call priority. For the purpose of an availability budget, power will be used because it is the leading cause of non-availability in this area.
