Information Technology Service Management

Running Head : INFORMATION TECHNOLOGY SERVICE MANAGEMENTBrian M . BohlmanInformation Technology expressive styleNovember 17th , 2007Dr . BurroughsSummaryThis was written to render background hold relevant to IT divine return perplexity . These complicate an overview of the IT floor depository library (ITIL , as well as a discussion of the major(ip) portion outations in ITSM special(prenominal) wholly toldy , IT- craft waiting line upment , ITIL bear on relationships the IT milieus univers every(prenominal)(prenominal)y encountered in ITSM applications , and the general affects of softwargon intersections that cont riding habit one or to a greater extent of the ITSM do byesIntroduction p The caution of instruction technology (IT ) at commode handicraftes has experienced a major lurch over the past 20 eld . IT had been traditionally social functiond as a back-office effect , k at a timeing to bread and besidester the immanent brings of a society . IT had , at time , startd almost singly of the argumentation it was non un usual for IT to operate in a silo , where IT supply was non set officularly concerned with how the systems they bonkd accept the moving in , as eagle-eyed as they were imprint . IT errors and shortcomings were generally experienced altogether by the billet employees , so IT had little direct imp run on the impression of attend to tryd by the personal line of credit to its customers (Macfarlane rudd 2001With the outcome of the pro prospects as a over faultfinding medium for conducting duty , IT s determination in the avocation spayd signifi washbowltly . No endless could IT plane sections hide in the background and operate put one overmingly independently of the lineage IT was now an integral component of the lineage . No longer ar the effects of IT s shortcomings limite! d to the byplay itself , ex shamly ar super visible to customers , and poor religious armed proceeds commit out cast off a direct seismic disturbance on the success or failure of the business . This shift in IT example and expo received prompted a contrasting method of managing IT , from focusing detailally on the IT components and devices themselves to managing IT by the work it bequeaths the business . This method of managing IT is called IT assistance oversight (ITSM (van Bon 2002IT sustenanceer expressive style (ITSM ) is a figure out-oriented counselling school of thought designed to support the provision of flavor business IT operate done the good and efficient allocation of IT resources and by aline IT with the endeavors of the business itself . ITSM , and in item , the ITIL framework of ITSM , has become progressively general in the United States over the past somewhat(prenominal) years , and is judge to become exceedingly prevale nt in most businesses in the coming years . This is driven by several factors : challenges in managing the increasing compositeity of IT purlieus , federal mandates such(prenominal) as Sarbanes-Oxley and the first forest standard for IT focus (ISO 20000 ) repay adapted to become widespread in the coming years . attri scarcelye management of IT is no longer a luxury it is a necessity (O Neill , 2006Although ITSM is outgrowth-oriented , companies more than employ softw argon light beams to support or automate portions of these answeres . As IT environments become more complex , and as businesses atomic recite 18 held more account able-bodied for their IT activities , these calculating machine bundle tools be change state increasingly principal(prenominal) in in effect and expeditiously managing a business IT resources and operate . Finding the right computer packet package to support a business ITSM buttes is critical these softw atomic make sense 18 to ols often withstand courts into the tens (or level! (p) hundreds ) of thousands of dollars to purchase and utilise , and selecting the wrong tool pile have a dire fiscal and emolument quality impact on a businessIT Infrastructure library (ITILThe IT Infrastructure Library (ITIL ) describes a line up of break in(p) practices for IT receipts complaint . It was designed as a expression to align internal IT departments with the business itself , and to promote the efficient and potent use of IT in support of quality business works . before developed in the U .K . in the mid-eighties by the Central Computer and Tele talks Agency (now part of the Office of governance Commerce , ITIL is widely recognized as the de-facto realitywide hail to ITSM , and is utilize by thousands of companies and makeups around the world . It is the basis for the ITSM standards BS 15000 and ISO 20000 (van Bon , 2002ITIL is delimit in a serial of books , but the substance of ITIL resides in two books : assistant bringing communication and redevelopment of border guard . These two books compendium the 10 carry outes and one function flummox in impressive and efficient IT emolument forethought . apiece bea for go close be described below emolument bringingThe enjoyment of assistant Delivery is to determine the resources necessary to submit quality IT utility to substance ab drug substance abusers and customers , and to turn back that these resources be utilized in a equal-efficient way . inspection and repair Delivery views the IT stand from a tactical perspective , and consists of five bear ones . A brief overview of individually process is provided below serve take aim vigilance . The wipeout of returns aim counsel is to importanttain and gradually improve business aligned IT dish quality through a changeless cycle of agreeing , monitor , reporting and reviewing IT fosterer achievements and through instigating actions to deplete unacceptable trains of inspection and repa ir answer Delivery , 2001 27 The mainstay compone! nt in assistant Level anxiety is the advantage Level contract (SLA . SLAs be negotiated and documented aims of IT service that the business agrees to provide to a customer or user . The IT root word is monitored to hold that these SLAs argon metfiscal counseling for IT serve . The last of Financial steering for IT overhauls is to provide cost potent stewardship of the IT assets and the monetary resources utilise in providing IT function assistant Delivery , 2001 , 61 This process is employ to en accredited that financial resources are organism utilized in effect and efficiently (via bud reign and accounting , as well as charging for function if necessaryCapacity direction . The ending of Capacity counselling is to derive the business requirements (the arrogate service deliverance , the brass section s process (the actual service delivery , the IT infrastructure (the means of service delivery , and master that all current and future capacity and f unctioning aspects of the business requirements are provided cost-effectively dish Delivery , 2001 121 This process balances tack versus demand and cost versus capacity to utilize the right level of resources (capacity ) to provide a quality serviceIT improvement continuity care . The polish of IT table service Continuity wariness is to support the boilers suit short letter Continuity prudence process by ensuring that the required IT technological and services facilities outhouse be recovered at bottom required and agreed business time-scales Service Delivery , 2001 , 163 This process deals with the ability of IT to recover from an unexpected yield or misfortune to attain an agreed-upon level of service at heart a take over timeframeAvailability focussing . The terminal of Availability heed is to optimize the gift of the IT infrastructure and supporting organization to deliver a cost effective and sustained level of availability that enables the business to satisfy its objectives Service Delivery , 2001 ! , 212 This process is answerable for making sure that the IT services are procurable according to the agreed-upon levels delimit in the SLAService validateThe purpose of Service backup man is to manage the day-to-day IT issues in such a way that a quality service is maintained . Service keep views the IT infrastructure from a short-run (operational ) perspective . A brief overview of severally process is provided belowService Desk . Service Desk is a function (not a process , and its endeavor is to act as the central prove of affaire amongst the drug user and IT Service instruction . To handle nonessentials and requests , and provide an user interface for some other activities such as substitute , riddle , flesh spillway , Service Level , and IT Service Continuity care (Macfarlane Rudd , 2001 ,11 Service Desk serves as the face of the IT department to the IT service user , and its main responsibilities are to record all calls received from the user , pr ovide first line support keep the user updated on status , and to provide management reportsIncident counsel . The goal of Incident Management is to set up normal service operation as quickly as workable with minimum noise to the business , thus ensuring that the top hat achievable levels of availability and service are maintained Service arrest , 2001 , 71 In ITIL , an incident is defined as any take which is not part of the standard operation of a service and which exertions , or may cause , an flutter to , or a decline in the quality of that service Service Support , 2001 , 71 The Incident Management process is often started at the Service Desk , who gathers user incident info and attempts to resolve the incident . If the Service Desk cannot resolve the Incident , it is summersaulted to the punt level of support . If second level cannot resolve the Incident , it will continue to pass down the levels of support (becoming more readinessed and alter individually le vel down ) until one conclave is able to restore the! service . The goal of Incident Management is not to hap a cause for the incident , but further to get service restored as quickly as possibleProblem Management . The goal of Problem Management is to derogate the wayward effect on the business of Incidents and Problems ca utilise by errors in the infrastructure , and to proactively prevent the item of Incidents , Problems , and errors Service Support , 2001 , 95 Problems are unknown causes of incidents . irrelevant Incident Management whose goal is merely to restore service as quickly as possible , Problem Management is tasked with determination the root cause of a caper (which turns the problem into a Known Error , then providing both a workaround or a permanent imbibe . Problem Management benefactors to reduce or prevent pass off Incidents from happening frame Management . The goal of Configuration Management is to provide a logical standard of the IT infrastructure by identifying controlling , maintaining , and ver ifying the versions of all Configuration Items in existence (Macfarlane Rudd , 2001 , 23 Configuration Management is tasked with gathering the schooling and relationships of all IT assets , including hardware , package package , spate (IT faculty , and even documents . Each IT asset is called a Configuration Item (CI , and all CI randomness and relationships are held in the Configuration Management Database (CMDB . Configuration Management works well with the other processes to run across that the CMDB is always up-to-date and accurate revision Management . The goal of Change Management is to ensure that standardized methods and procedures are used for efficient and prompt handling of all Changes , in to defame the impact of any related Incidents upon service Service Support , 2001 , 165 Change Management provides a formal process for making any Change to the IT infrastructure (for instance , to good deal a Problem . Change Management is tasked with reviewing Requests for Change (RFCs , reviewing them , and each approving ! or rejecting the request sprain Management . The goal of kindling Management is to take an holistic view of a Change to an IT service and ensure that all aspects of a Release , both technical and non-technical , are considered unneurotic Service Support , 2001 Release Management performs the actual change to the IT infrastructure authorise by Change ManagementMajor Considerations there are a cast of aspects of ITSM that are important to consider These considerations take on IT-business concurrence , process relationships , the IT environment , and ITSM software returnIT-Business AlignmentThe cell nucleus aspect of ITSM is the effective and efficient utilization of IT resources in support of the goals of the business . This alignment between IT and the business ensures that both sides are working together towards a parking lotplace goal , and encourages communication and understanding between both parties (van Bon , 2002 ) ITIL breaks IT down into iv main components (O Neill , 2006People . IT supply responsible for designing , implementing , supporting and managing IT servicesProcesses . The ITSM processes used to provide quality IT services (ITILProducts . Hardware and software carrefours used to provide the IT services , as well as those that support or automate the defined ITSM processesPartners . Third-party suppliers , vendors , and others that support the business throng , processes , and harvest-tidesPeople , Processes , Products , and Partners bump off up the 4 Ps of ITIL and are considered the four key components in implementing an effective and efficient ITSM solution . Properly managed and utilized , these four components allow IT to support the business . In ITIL , process competency and effectiveness is determined by defining and collect randomness on Key Performance Indicators (KPI ) and metrics for each process . The analysis and review of this data is very important to ensure that IT is right functioning , and th at IT is properly supporting the business (RL Consul! ting , 2006Process RelationshipsThere are a great deal of dependencies and interactions between the ITIL processes , not only within the Service Support and Service Delivery modules , but in addition between processes in diametric modules . These relationships are a critical aspect of effective IT Service Management and are described in detail in the Service Delivery and Service Support books of ITIL . Some of the key relationships take (van Bon , 2002Configuration Management . Configuration Management stores all of the var. items within the IT environment in the CMDB . thereof all of the other processes interact with Configuration Management in to gather information astir(predicate) the IT organization and update the CMDB when necessaryService Desk . Service Desk serves as the main localize of pass on for Users , or people who use the services provided by IT on a day-by-day basis (can be internal or extraneous to the business . It relies on Incident Management for the r eady gag rule of Incidents , Problem Management to find the root cause of come about Incidents and to provide a workaround or solution , Change Management to approve Changes to the IT environment that will solve these Problems , and Release Management to build and deploy the solution to the IT environmentService Level Management . Service Level Management serves as the main pose of contact for Customers , or those who pay for and own the IT services provided by the business (like Users , can be internal or external to the businessIn to piss SLAs that the business can uphold , Service Level Management moldiness work with all of the processes (except Release Management ) to understand the capabilities of IT . It must too be made awake(predicate) of the major challenges or issues within IT , so that the Service Level Manager can discuss this with the Customer in the event that a SLA is breached . cod to the high level of interaction between the processes in ITSM , the people and reapings that support these processes must also be ! very synergistic . ITSM promotes cross-functional teamwork and communication in to provide quality IT services (Higday-Kalmanowitz and Simpson , 2005IT EnvironmentAlthough either IT environment that employs ITSM is distinguishable , some common characteristics of a common IT environment interested in implementing ITSM are shown below (van Bon , 2002Large environments . Although ITSM processes are applicable to any IT environment , they are typically found in cosmic organizations (Fortune 1000 . The IT staff for these organizations is often tasked with managing a coarse number of IT overlaps and systems , and supporting and delivering a large number of IT services . The number of servers , network equipment , software proceedss , etc .

that must be managed and supported can number into the thousands (or tens of thousands , depending on the size of the political party and their emphasis on IT in providing servicesHighly complicated . also organism large , most IT organizations that embrace ITSM work in highly heterogeneous environments . That is , the environment is made up of a number of different technologies , productions and systems . These different technologies , products , and systems must often be able to communicate and work with one another(prenominal) in to be usable , and integration challenges are commonLarge number of Customers and Users . Most large IT environments serve a large number of Customers and Users that rely on the provided IT services to function effectively . These Customers and Users can be either internal or external to the business . Properly managing issues requests , and in quiries for a large number of Customers and Users can! be very hard to do , and is a big point of emphasis with many companies todayMultiple IT staff groups . For most medium and large environments , IT staff is often busted into a number of specialized groups that focus on specific aspects of the IT environment . In to effectively implement ITSM , these staff groups must be able to inlet relevant information about the IT environment and issues within the environment and must be properly managed to ensure their time and skill sets are utilized in the best way possibleThese IT environments are generally very complex , and are very difficult to manage well without an effective process framework . Besides the right processes , the right people , products , and fellows are also required for success in ITSM . once the right processes are use , and the right people are properly trained , finding the right software product (provided by the right partner ) to support the people and processes is the following(a) critical step (Higday-Kalm anowitz and Simpson , 2005ITSM computer software ProductWithin ITSM , there are many areas that can bene give-up the ghost from automation or support provided by a software product . Some of the common uses of software within ITSM include (Turner , 2004 : build and maintaining a CMDB propellant service modeling and dependency role Seamless service desk integration Policy-based workflow automation capabilities Service catalog /financial modeling and reporting observe changes within the IT infrastructure Monitoring IT s compliance of SLAsITIL recognizes the fact that software tools are often busy in the support of ITSM processes . While ITIL does not specify a specific process for evaluating an ITSM product , it does bring up some valuation criteria . These criteria , outlined in Service Delivery (2001 ) include confluence 80 of functional and technical requirements Meeting all mandatory requirements Supporting IT Service Management best practices Ensuring product is business -driven , not technology-driven Addressing security a! nd integrity considerations Ensuring training and consulting services are available Adequate report generation capabilitiesDue to the different requirements and functions for each of the ITSM processes , the varying ways in which these processes are enforced in each company , and the variability within different IT environments , it is impractical to come up with a strict set of requirements that any ITSM software product must adhere to (Wiegers , 1999 ) There are however , some basic considerations that will credibly do to many of these products . Some of these considerations are discussed below (Higday-Kalmanowitz and Simpson , 2005Should be highly configurable . A critical aspect of selecting an appropriate ITSM software product is making sure it properly supports the ITSM processes already defined and implemented within the business In to support the realized ITSM processes , the software product should provide a high level of configurability to fit within a particular env ironment . unwashed areas of configuration include user interface , data aggregation , event monitoring and notification , and reportingShould provide strong integration capabilities . rarely (if ever ) do ITSM products operate independently . In for an ITSM software product to properly support the ITSM processes and the heterogeneous IT environment the processes manage , it must be able to integrate and interface with a number of different products and technologies . Popular communication methods between IT components , such as Simple Network Management communications communications protocol (SNMP , Extensible Markup Language (XML , and Remote Procedure Call (RPC ) help in the integration of products and systems . The use of agent software is also commonly usedShould be easily reachable . Due to the highly relational nature of the ITSM processes and the distributed nature of IT staffing , ITSM software products should be cordial by multiple IT staff groups in multiple location s . entanglement technology and the use of client s! oftware is a common way of making products available across the IT organization . some other related aspect of accessibility is security . The product should provide access control capabilities that allow personnel to see information that they subscribe to to do their jobs , but nothing elseShould be light-colored to use . ITSM products , while often complex to implement and get by , should be lightheaded for IT staff members to use . The IT environment (on the Service Support side in particular ) can be very hectic at times in for IT staff to properly support this environment , these products need to be able to quickly provide staff members the information they need to do their jobs . Therefore , the product interface should be intuitive and easy to read , certain functionality within the product should be machine-driven whenever possible and relevant information should be readily available (Puka et al 2000ConclusionIn this , a framework of IT Service Management was examined . The considerations discussed above , as well as all others pertaining to selecting an appropriate ITSM software product , all stem from an primal requirement that the product be a good fit for the environment (business and IT ) in which it will operate . The software product does not have to work well in a number of different environments , but for one specific environment only . Therefore , a good understanding of the specific business and IT environment is a critical step in choosing the right software productAs businesses begin to understand the value that IT can provide to their organization and as these businesses continue to embrace IT Service Management , software products that support ITSM will become critical to a business ability to provide quality IT and business services . With the education and maturation of a specific evaluation framework for these products , businesses will have a way to better identify products that properly support their ITSM initiativesRefer encesHigday-Kalmanowitz , C , Simpson S .E (Editor (2! 005 .
