ITIL Foundation Course
-
IT Infrastructure Library A series of documents, originally created by
the Office of Government Commerce An integrated set of best-practice
recommendations with common definitions and terminology.
Divided into a series of eight documents / books, known as 'sets'. The sets themselves are sub-divided into 'disciplines', which cover individual subjects.
-
History of ITIL ITIL was created in the 1980's by the
UK governments CCTA (Central Computer and Telecommunications Agency) with the objective of ensuring better use of IT services and resources.
-
History continued The ITIL concept emerged in the 1980s, when the British
government determined that the level of IT service quality provided to them was not sufficient. The Central Computer and Telecommunications Agency (CCTA), now called the Office of Government Commerce (OGC), was tasked with developing a framework for efficient and financially responsible use of IT resources within the British government and the private sector.
The earliest version of ITIL was originally called GITIM, Government Information Technology Infrastructure Management, focusing around service support and delivery.
Large companies and government agencies in Europe adopted the framework very quickly in the early 1990s.
-
History continued In year 2000, The CCTA merged into the
OGC, Office for Government Commerce and in the same year, Microsoft used ITIL as the basis to develop their proprietary Microsoft Operations Framework (MOF).
In 2001, version 2 of ITIL was released. The Service Support and Service Delivery books were redeveloped into more concise usable volumes.
It is now, by far, the most widely used IT service management best practice approach in the world.
-
ITIL Benefits Describes a systematic, professional
approach to managing IT services. Emphasizes the central importance of
meeting company requirements economically.
-
ITIL Benefits Adhering to the best practice approach described in ITIL has the
following benefits for an organization: Support for the business processes and the tasks of IT decision
makers Definition of functions, roles and responsibilities in the services
sector Reduced expenditure in developing processes, procedures and job
instructions. Improved customer satisfaction through better and measurable
availability and performance of the IT service quality. Improved productivity and efficiency through the purposeful use of
knowledge and experience. Basis for a systematic approach to quality management in IT service
management. Improved employee satisfaction and reduced fluctuations in
personnel levels. Improved communication and information between IT personnel and
their customers. International exchange of experience (http://www.itsmf.com/)
-
ITIL Certification An established and well defined
certification scheme is in place to support ITIL.
This comprises three distinct levels: Foundation, Practitioner and Manager.
-
ITIL Certification The Foundation Certificate enables
understanding the terminology used within ITIL.
A prerequisite for the Practitioner's and Manager's Certificates
The Practitioner Certificate focuses upon the understanding and application of the specific processes within the IT Service Management discipline.
The Manager's Certificate is aimed at experienced professionals, who will be involved in managing service management functions.
-
Contents of ITIL
ITIL comprises the following five basic elements:Business perspective; Application management; Service delivery (provision of IT services); Service support; Infrastructure management;
-
Contents of ITILITIL is organized into a series of sets, which themselves are divided into two main areas:
service support and service delivery (i.e. Service Management)
The remaining six sets are:Planning to Implement Service Management,Software Asset Management, Application Management, Security Management, The Business Perspective and ICT Infrastructure Management.

Service Management
-
Introduction The realization that IT services assume ever-greater
significance has led to the introduction of IT service management.
Service management aims to provide a decision-making benchmark from a process-related perspective, and to provide professional implementation with defined contact partners.
An unconditional willingness of both managerial and other staff to become more customer and service oriented is a prerequisite within organizations.
While in the past attempts at problem solving were primarily focused on the investment in tools (product and technology-oriented approach), the ITIL approach primarily involves defining the processes with the particular services to be performed providing the framework for the definition. Only in the second instance are the requisite supporting tools
then procured.
-
Introduction The introduction of effective service
management makes it necessary to focus less on functions and components and more on an approach guided by the business process.
In many enterprises, this requires a cultural change. This important point must always be taken into account when implementing service management. Only if top management leads the way by example and
promotes this new culture, successful implementation can be achieved.
-
Benefits Improved IT service quality which takes into
account the needs of the enterprise. Improved communication with users by
using the same language and by exchanging up-to-date information.
Greater flexibility and thus improved scope of action for the enterprise when market situations change.
Improved customer satisfaction by assuring the best possible (measurable) quality of service.
Qualitative increase in safety and security, availability and performance of IT services.
-
Implementation Strategy Define the mission and the extent of the process. Initiate an awareness campaign. Describe process steps and procedures. Determine tasks, authority and responsibility of both
managerial and other employees (roles). Determine training needs of employees. If required, select and implement tools. Define types of reporting (management and other
processes). Implement processes. Initiate and monitor a continuous improvement process.
-
Factors Critical to Success Develop a good understanding of customer
requirements and business activities. Develop business-oriented rather than
technology-oriented services. Improve customer satisfaction by ensuring
measurable service quality. Improve resource utilization. Recruit target-oriented service employees
who have a clear understanding of customer requirements.
-
Possible Problems Excessive bureaucracy in process
documentation. Employees who do not understand service
processes. Lack of a clear understanding of the
process objectives. No visible genuine benefit; no reduction in
service costs; no improvements in quality. Unrealistic expectations that cannot be met
-
Service Desk
-
Definition The service desk is the central point of contact
between the customer and the IT area in all matters concerning IT services.
This includes help desk functions as well as coordination of change requests, service level management, configuration management and all other service management processes of ITIL.
The service desk is not a process but a function within the service organization. In its special role as a first point of contact with the
customer, the service desk is of great importance, all the more so since it embodies the image and the quality of service of the IT organization.
-
Description The service desk is the single point of contact in a service
organisation. The interests of customers are represented within the
service organisation through the service desk. A principal task of the service desk is to coordinate and act
as a central point of information between customers, internal service organisations and external providers. Determining the service desk structure and selecting
appropriate staff depends on a number of important factors concerning the form and type of the enterprise.
As the enterprise changes, the structure of the service desk will need to be changed accordingly, on an ongoing basis.
-
DescriptionBasically, there are three service desk structures: Local service desk:
Each location or each department in an enterprise has its own local service desk unit. Advantages are optimal proximity to the customer and therefore the ability to reflect their individual needs more closely.
Central coordination and standardisation of processes are some of the most demanding tasks required for the local service desk.
Central service desk: A single service desk responsible for all organisational units. Advantage of easy handling and standardisation of processes
however difficult to manage and problem with different languages and time zones.
Virtual service desk organization: Combines aspects of both of the organisational forms described
above. Information can be kept centrally and made available globally.
Local service support units provide on-site support to customers, with the central service desk unit being responsible for all inquiries as well as for coordinating the service organisations involved.
-
Tasks Act as a single point of contact for customers Register and follow up incident reports and complaints Keep customers informed about the status and progress of
their inquiries Carry out initial screening of customer inquiries and initiate
processing based on the agreed service level Monitor adherence to the service level agreements and take
appropriate measures if there is a danger of failure to meet an agreement
Formal conclusion of inquiries including monitoring customer satisfaction
Coordinate second level support and third-party support units
Provide management information to improve the service quality
-
Benefits Improved customer service and thus greater customer satisfaction Improved access to information through a single point of contact Faster and qualitatively improved handling of customer inquiries Improved teamwork and communication within the service
organisations Better focus on customers and a proactive approach to the
provision of services Reduction of negative effects on the enterprise when
troubleshooting Better controlled and managed IT infrastructure components Enhanced use of IT support resources and thus increased
productivity Better and more meaningful management information for decision
making Identification of customer training requirements for improved
utilization of services
-
Key Performance Indicators
Increased customer satisfaction Reduction in incident reports and complaints Reduction in service costs Improved coordination of IT service tasks
with the internal and external bodies involved
More highly motivated service employees
-
Service Support According to ITIL, IT service management
distinguishes among three levels of processes to be supported. These levels are as follows:
Strategic level: Management of IT services; this includes quality
management and IT service organisation, among others.
Tactical level: Planning and control of IT services = Service Delivery
Operational level: Support of IT services = Service Support.
-
Service Support Service Support is synonymous with
the efficient provision of IT services. Effective support of IT services is ensured by the following IT processes: Incident Management Problem Management Configuration Management Change Management Release Management
-
Incident Management
-
Incident Management - Objective
The primary objective of incident management is to restore the service as soon as possible while minimizing any negative effect on business processes
-
Incident Management - Tasks Identify and document all enquiries and incident reports. Prioritise (determine urgency) and categorise (risk-assess)
the messages. Provide initial incident analysis and initiate first-level
support. Hand on to second-level and third-level support if the fault
cannot otherwise be fixed. Increase the resources if there is a danger of failing to meet
the agreed service levels. Fix the fault and restore the service. Finalise and document the incident. Monitor, track and communicate progress in processing
incidents. Evaluate incidents and prepare reports on service
improvements; these reports will be used in discussions with customers and suppliers.
-
Incident Management - Description
Incident management involves processing enquiries and incidents of all types.
This is achieved by a group of specialists who work in virtual unison.
In line with the specialist skill levels of their members, these teams are grouped into first-level, second-level and third-level support units.
In this function, incident management assumes the particular role of maintaining contact between IT systems and business.
Together with the service desk, incident management is the first and most important point of contact for the customer.
-
Incident Management - Benefits Reduction in the negative effect which incidents have on
business processes. Reduction in support costs and hidden IT costs (duplication
of resources). Service improvements can be detected early. Improved availability of business-related information
concerning performance in the context of the service-level agreement.
Performance increase as a result of improved use of human resources.
Incidents and service requests are documented centrally; there is much less likelihood of loss of information.
The use of the configuration management database in the incident management process results in more frequent updating of entries and thus a more up-to-date database.
Increased user satisfaction thanks to better and faster incident handling.
-
Incident Management - Keywords
Incident: fault, error, malfunction, etc. SPOC single point of contact
-
Incident Management Key Performance Indicators
Adherence to the agreed service level; IT costs; Customer satisfaction; Response and processing times; Self-resolution rate;
-
Problem Management
-
Problem Management - Objective
The objective of problem management is to prevent and reduce incidents as well as to provide quick and effective problem solving to ensure a structured use of resources.
-
Problem Management - Description
Problem management is of central importance to the entire service support sector.
It includes the handling all failures of IT services from the special aspect of identifying the actual underlying cause.
This includes recommending changes concerning configuration items (CIs) to change management.
Problem management processes use information provided by various other processes (e.g. by incident management or by change management).
Moreover, problem management takes a proactive approach in which weaknesses are detected early and preventive measures are taken.
-
Problem Management - Benefits
Continuous and more stable IT services; Increased user productivity through reduced
downtime; Increased productivity of support staff; Error prevention; Reduction of the effects by taking advantage of
records which document earlier problems; Improved relationship between users and IT services
due to higher quality of services; Better control of services through improved
management information.
-
Problem Management - Tasks
Problem handling: Identify, document, classify and analyse the problem. Error handling: Identify, document and evaluate the error, plan and
initiate troubleshooting (RC). Incident support: Support the handling of more involved incidents. Proactive Problem Management: Measures of error prevention: trend analyses, actions
and measures, preparation of quality reports.
-
Problem Management Keywords
Known error (the error is documented, the cause of the problem is known, a workaround exists).
RFC - Request For Change: proposal for rectifying the error.
-
Problem Management Key Performance Indicators
Reduction and absence of incidents (reduction of the pain factor);
Increased availability of the service; Greater customer and employee
satisfaction; Reduced support costs; Increased safety and security when
expanding systems, through a systematic approach.
-
Configuration Management
-
Configuration Management - Objective
The objective of configuration management is to provide up-to-date secure information via the configuration elements in use, thus ensuring direct interlinking with all other disciplines of IT service management
-
Configuration Management - Description Every enterprise depends on the economical
provision of IT services. From the point of view of legal and financial aspects alone, operation and administration of IT assets is becoming ever more problematical.
Configuration management makes it possible for IT management to be in control of these IT elements and assets (e.g. hardware, software, documentation, licences, etc.).
According to ITIL terminology, such elements are called "configuration items" (CIs).
CIs show the interconnection of the individual elements in the IT infrastructure.
-
Configuration Management - Description
Well-functioning configuration management provides an enterprise with: Precise and up-to-date information on all components
which are required to perform a business process (from the point of view of service rather than of components)
More direct control over the IT assets used The ability to economically perform high-quality
informatics services Apart from this, configuration management provides
fundamental information for calculating costs and invoicing work performed, within service level management "
-
Configuration Management Tasks I
Configuration Management Planning Determine the objective and extent of configuration management Take into account existing instructions, standards and processes concerning the
support organisations Develop nomenclature for the configuration items, if they do not exist already Determine the role and responsibilities of configuration management, together
with management Determine what functions are required from configuration management Establish a workflow for operational processes Specify a timetable and a process for implementing configuration management
activities (configuration identification, checking, documentation of status changes, auditing)
Analyse integration requirements using third-party products Create a configuration management system design (CMDB, location, interfaces to
system management and support tools etc.) Provide training and coaching for employees Configuration Identification
The IT infrastructure configuration should be divided into unambiguously identifiable items (CIs), so that these can be effectively checked, monitored and reported on, according to the requirements of the business. The degree of detail should be determined optimally, in line with the practical and individual requirements of the enterprise.
-
Configuration Management Tasks II
Control of Configuration Items (CIs) Register new CIs and their versions Document changes to CIs (status-update, changes to CI attributes, changes in
responsibilities, licence control, relationship to other CIs etc.) Document changed CIs based on changes Protect the integrity of configuration data Proof of Configuration Status Proof of status is periodically furnished in the form of reports. As a rule this
involves the following information: Unambiguous identification of the configuration elements including their current
status (installed, being tested, under development, etc.) The configuration baseline, the current release and its status Nomination of the person who is responsible for changes Unsolved problems, change-requests in relation to individual configuration
items Configuration Check and Audit Check that the processes of configuration management are being adhered to
Check that the consistency and integrity of the data is ensured Check that changes in configuration items are entered in a timely manner
-
Configuration Management Keywords Configuration Management Database CMDB
The configuration management database CMDB contains all the data required for the production of goods and services, including a description of the individual configuration items and their interconnection (metadata).
Providing the right degree of detail when defining this database is of central importance for successful and economical introduction of configuration management
CI Configuration item: data entity to be described in
the CMDB
-
Configuration Management - Benefits
Increased effectiveness of the other disciplines within service support and service delivery, and thus improved quality of service
Creation of an optimal overview of the IT infrastructure in use, as a basis for inventory data and planning data
More efficient administration of the IT resources used More efficient handling of incidents and problems Better control of hardware and software changes Easier adherence to legal provisions Improved monitoring and control of the assets used Simplified expense budgeting Support for contingency planning
-
Configuration Management Key Performance Indicators
Quality and current status of data Completeness (degree of coverage) Availability to other service
management processes Process costs
-
Change Management
-
Change Management - Objective
The objective of change management is to carry out changes economically and in a timely manner with minimal risk.
-
Change Management - Description
Experience shows that a high proportion of problems with IT service quality can be traced back to some change.
Changes to the IT infrastructure always result in problems, which cost much more to rectify than the actual cost of the change itself.
Such problems are enormously expensive, so that enterprises and customers are increasingly reluctant to accept them.
To be sure, every development of the IT infrastructure, whether relating to capacity management or problem management, is associated with change measures which in turn pose a degree of risk.
For this reason a very strict approach to effective change management is sensible.
-
Change Management - Tasks Receive and record requests for change (RfCs); Assess the ramifications, costs, benefits and risks of the
planned changes; Update the change / release plan; Coordinate and control the implementation (in change
advisory board, CAB); Monitor the success of implementation and report on it; Update the configuration management database; Complete and review the RfCs (post-implementation
review).
-
Change Management - Keywords RfC (Request for Change)
Requests for change (RfCs) are evaluated for possible ramifications, urgency, as well as costs and benefits. Subsequently, the changes are prioritised and released.
CAB Change Advisory Board The change advisory board assists in assessing the
ramifications of proposed changes, planning preparation and providing the required resources.
Classification takes place based on the risk (category) and the priority (urgency and pain factor) involved.
PIR Post Implementation Review Through subsequent review in the production
environment, the quality of the change and of the change process is assessed. Measures should feed into the continuous process of improvement.
-
Change Management Key Performance Indicators
Number of successfully introduced changes;
Ramifications of unsuccessful changes; Process costs; Track record for meeting deadlines.
-
Change Management Benefits
Controlled changes and thus fewer instances of loss of quality caused by changes;
Early detection of risks; Fewer changes involving errors or incidents; Valuable management information about planned and
implemented changes and their ramifications; More stable services and thus increased user productivity: Improved productivity of the IT specialists involved; Better ability to overcome times of high change-density; Ability to restore the original state, in the case of
problems.
-
Release Management
-
Release Management - Objective
The objective of release management is successful planning and control of hardware and software installations.
-
Release Management - Description Change measures are bundled to keep downtime and risks
to a minimum during hardware or software changes. The term ""release"" refers to one or several authorised IT
services change measures. Dependencies between a particular software version and
the hardware required to run it determine bundling of software and hardware changes which together with other functional requirements constitute a new release.
Release management ensures successful planning and control of hardware and software installations. The focus is on protection of the productive environment and its services by using formal procedures and checks.
Release management is carried out based on the configuration management database so as to ensure that the IT infrastructure is up to date.
-
Release Management - Tasks Determine the release policy; Define and implement releases; Carry out release tests and acceptance; Plan and implement rollout; Provide information and training prior to delivery; Install new or modified hardware; Store the released hardware in the definitive
hardware store (DHS); Release, distribute and install the software; Store the released software in the definitive software
library.
-
Release Management Release Types Full release: All components of the release are
developed, tested, distributed and implemented together.
Delta release: Contains only those components (CIs) which have been modified since the last release.
Package release: Individual independent releases as well as full releases or delta releases are combined in one package.
Emergency release: Emergency release is required in the case of difficult or high-priority problem solutions. Emergency releases should be used very sparingly since they interrupt the normal release cycle and are extremely fault-prone.
-
Release Management - Keywords
DHS Definitive Hardware Store: Tested and released hardware is stored in a secure environment away from the production environment in one or several places. These replacement components and assemblies are kept at the same release level as the systems in the production environment.
DSL Definitive Software Library: The contents of software releases are documented, and the currently approved software versions are stored as an autonomous component of the CMDB in a safe environment in the DSL . Backup copies are always stored away from the premises. Furthermore, the DSL contains documentation to identify the release status of all software in use.
-
Release Management Release Policy
The release policy defines the level of the IT infrastructure that is to be controlled by definable releases; Defines the nomenclature and the numbering system; Provides the delimitation between major and minor
releases. In addition, the provisions for an emergency release are established;
Maintenance-Windows for times, which are non-critical to business, are defined. After these waiting times, releases can be installed;
The policy also serves as a guide for preparing the release documentation (release notes);
A determination is made whether a rollback procedure is required in place, how the quality of the release is ensured (review meetings, impact analyses etc.);
In the release policy, agreed roles and responsibilities are defined;
Software requirements so that it can be accepted in the DSL.
-
Release Management Release Plan Release planning comprises the following:
Define the release content; Coordinate roles and responsibilities; Coordinate phases (times, locations, business
sectors and customers); Prepare a release schedule; Plan the use of resources (including overtime); Prepare backup plan (roll-back); Develop a quality plan for the release.
-
Release Management Benefits
In conjunction with configuration management, change management and the operational tests to be carried out, the following benefits arise: Reduction of the error rate in released software and hardware; Minimization of service interruptions by synchronizing the
release through bundling of software and hardware components; Certainty that the production hardware and software is of good
(or known) quality; Stable test and production environments; Improved use of user resources through a combined effort
during testing of new releases; Proper monitoring and protection of the hardware and software
on which the organization is strongly dependent; Consistent software across all systems; Detection of incorrect versions or unauthorized copies; Reduction in the danger of virus infection or other unauthorized
interventions.
-
Release Management Key Performance Indicators
Process costs Stability of hardware and software Number of fault-free roll-outs delivered on
time Number of errors found during testing Software that has been installed in full
compliance with licence laws Number of viruses in the system
-
Service Support Looking Back Service Desk Configuration Management Incident Management Problem Management Change Management Release Management
-
Service Delivery
Service Delivery is synonymous with the provision of IT services that come up to customer expectations. This is ensured by the following processes: Service Level Management Capacity Management Availability Management IT Continuity Management Financial Management
-
Service Level Management
-
Service Level Management Objective
The objective of service level management is to draw up, monitor and control the service level agreements and their underlying service quality.
-
Service Level Management Description Service level management is a central function of IT
service management and is responsible for qualitative and quantitative control of the services.
The service level agreement (SLA) constitutes an essential element of service level management.
An SLA is an agreement between the IT organisation and its customers, wherein the services to be performed are determined end-to-end.
This includes both qualitative and quantitative specifications, such as performance and availability of these services.
Internal safeguarding of service agreements is through operation level agreements, OLAs.
-
Service Level Management Description In addition, support agreements or maintenance
agreements are signed with external providers (underpinning contracts).
It is essential that in assessing service quality, service level management takes into account all factors of service management.
Clear and intelligibly worded SLAs, which can be measured in practical application, are an important prerequisite for the assessment and implementation of most activities within the IT organisation.
Detailed information contained in an SLA is used to measure system values.
It also provides the IT organisation with concrete figures for evaluation and subsequent measures.
-
Service Level Management Keywords Service Level Agreements
At the very least, a service level agreement should document or contain the following elements: Parties involved and signatures; A simple description of the service and the
performance characteristics; Agreed service times; Reaction times in relation to users, handling of
incidents and RfCs; Targets of availability, safety and security, and
continuity of service; Obligations of customers and providers; Critical business hours and exceptions.
-
Service Level Management Keywords Operation Level Agreements
OLAs are internal agreements relating to the supply of services by other internal support organisations.
OLAs separately describe the individual components of the overall services performed for the customer.
Often they contain an OLA for each support group and an agreement for each supplier.
OLAs and SLAs can be signed with external suppliers to supplement external agreements.
-
Service Level Management Keywords Service Catalogue
The service catalogue contains an overview of all services to be performed including their characteristics. This catalogue documents a mutual understanding of all the services offered, as well as their components, features, costs etc.
The service catalogue should include the following: Information obtained about the services from the IT
operations; Customer and user requirements; Persons responsible for maintaining and further
developing the catalogue. SIP
Service improvement program; measures for continued improvement of the SLM process.
-
Service Level Management Tasks
Negotiate and agree on service level requirements with business and customers;
Monitor and report on the actual service level (service level reporting);
Plan and implement continuous improvements in service levels;
Coordinate service management and service support functions;
Conduct service review meetings with customers; Implement service improvement programs; Monitor the changing requirements of the enterprise and
amend the service level agreements accordingly; Amend the operation level agreements and the support
agreements with external suppliers; Prepare and maintain a service catalogue.
-
Service Level Management Benefits
The required level of service is unambiguous, consistent and measurable;
There is an appropriate balance between the desired level of services and the costs incurred through this;
Exact specifications help achieve savings; Customer productivity is enhanced by the provision of
improved services; Objective proof of the service quality delivered helps
prevent differences of opinion; The number and the ramifications of requirements that
were not planned-in are reduced; The relationship between the IT customer and the
provider is improved.
-
Service Level Management Key Performance Indicators
Extent of coverage of the IT services; Number of deviations from the agreed
service levels; Customer satisfaction; Availability of the services; Performance of the services; Process costs.
-
Capacity Management
-
Capacity Management Objective
Capacity management ensures that the resources necessary to meet the agreed customer requirements are provided economically.
-
Capacity Management Description
Capacity management ensures that quantitatively and economically tenable IT capacity is always available to cater for the requirements of the business in terms of transaction volume, processing time and response time.
Capacity management ascertains business requirements for IT resources, forecasts the workloads necessary to provide them and carries out planning of the IT resources.
By means of performance management, the effective performance of the resources provided is documented.
-
Capacity Management Tasks Providing proof of economical capacity utilisation and the
preparation of a capacity plan is one of the most important results of capacity management.
Determine customer requirements (=demand management);
Transpose the requirements to system utilisation (=workload management);
Determine the required resources (=resource management);
Prepare a capacity plan; Monitor the performance and carry out fine-tuning
(performance and tuning); Carry out improvements to achieve the agreed service
level.
-
Capacity Management Keywords I CDB
The capacity management database contains information about capacity utilisation and performance of IT services
The input for the database comprises the following information: Business data; Service data; Technical data; Financial data; Capacity utilisation data.
The following information can be compiled from the CDB: Service and components report (capacity utilisation); Exception reports; Capacity and planning data (forecasts).
-
Capacity Management Keywords II Demand Management
Business requirements and growth expectations based on business development are determined by means of demand management. Business plans and business strategies form the basis for this.
Workload Management The IT services are adapted (expanded, service
times adapted, optimised etc.) on the basis of demand management.
Techniques used for this include trend analysis, simulation, and baseline method.
-
Capacity Management Keywords III Resource Management
Administration and procurement of resources (finances, physical resources, and employees)
Performance Management Monitoring, checking and regulating (e.g. by
prioritising) service performance Capacity Plan The capacity plan contains:
Actual capacity utilisation; Desired capacity utilisation; Basis for budget planning.
-
Capacity Management Benefits
Improved economy in the production of goods and services through better utilisation of the resources used.
Reduction in the probability of capacity bottlenecks occurring; Better use of available resources; Basis for monitoring capacity costs and thus early detection of
step costs; Improvement in customer relationships; More precise definition of performance requirements; More precise forecasting concerning the expected
performance behaviour of systems; More efficient use of employees; Better structured procurement of hardware expansions; Improved understanding of the interrelationship between
performance problems and capacity problems.
-
Capacity Management Key Performance Indicators
Workload of IT services; Reserves; Number of bottlenecks; Capacity utilisation rate of human
resources and systems; Costs: economic use of resources; Ability to meet deadlines when
providing resources.
-
Availability Management
-
Availability Management Objective
Using availability management, ensure the availability of IT services as specified by the customer.
-
Availability Management Description
Availability management provides for reliable access to IT services. Availability means that the customer will always receive the expected services when they are needed.
Good availability requires a low error or failure rate. If there is an incident or malfunction, it has to be rectified quickly.
Furthermore, availability management ensures that maximum benefit is gained from the existing IT infrastructure and services.
Such maximum benefit is ensured by reliability of the services, and the ability to service and maintain the IT infrastructure.
-
Availability Management Tasks
Determine availability requirements; Prepare availability forecasts and plan the required measures; Prepare an availability plan; Determine the actual availability; Prepare reports; Improve the agreed availability. Improvement of availability, for example, is achieved by
applying the following methods: CFIA component failure impact analysis; Fault-tree analysis; CRAMM: risk analysis with a counter-measure plan; SOA system outage analysis; structured cause analysis; Ongoing improvement in conjunction with support
organizations.
-
Availability Management Keywords Reliability (mean time between system
incidents or MTBSI) Reliability is the capacity to maintain
operational services. Maintenance or restoration of services takes place in the following steps: Error prevention; Error detection (incidents); Error diagnosis (problems); Error repair (known errors); Restoration of the service.
-
Availability Management Keywords Maintainability (mean time to repair or
MTTR) Maintainability is the ability to keep the
services operational. Maintenance or restoration of services takes place in the following steps: Error prevention; Error detection (incidents); Error diagnosis (problems); Error repair (known errors); Restoration of the service.
-
Availability Management Keywords Serviceability
Serviceability describes the performance to which external suppliers are committed in relation to certain components of the IT infrastructure or services" MTTR mean time to repair (maintainability); MTBF mean time between failures
(availability); MTBSI mean time between systems
incidents (reliability).
-
Availability Management Benefits IT services are designed and controlled so
that contracted availability is achieved; Service quality improves; New systems become more economical; The requirement for problem support
diminishes; Maintenance and down time are reduced; Supplier performance is improved; More detailed information is available for
service level negotiations; Existing IT resources are used more
efficiently.
-
Availability Management Key Performance Indicators
Costs can also be determined by assessing non-availability:
Productive time lost by customers; Productive time lost by IT resources; Income lost; Overtime supplements for support teams; Materials consumed; Penalty for contract non-performance; Image loss vis--vis customers; Lost business opportunities; Reduced customer satisfaction.
-
IT Service Continuity Management
-
IT Service Continuity Management - Objective
The objective of IT continuity management is to safeguard the performance of services in any eventuality based on planning and implementation of preventive measures.
-
IT Service Continuity Management - Description Enterprises depend to a significant extent on the
availability and functionality of the information technology in use.
Therefore, preparation for an eventuality, combined with business continuity management, assumes ever greater importance, with the specific goal of safeguarding the availability of services, taking preventative measures to reduce the probability of failures and, if a catastrophic event should occur, restoring services in the required time.
-
IT Service Continuity Management Description The IT continuity plan is always based on a higher-level
business continuity management plan (BCM). Strategic and business policy risk evaluation of IT
services has to be undertaken by business management. Feasibility and expenditure are determined by IT; in the
final analysis they thus have an influence on the service level required.
-
IT Service Continuity Management - Tasks Carry out risk analyses as part of business
continuity management; Prepare recovery plans for IT services; Provide the required means; Provide employee training; Test and verify plans to be able to restore
the services in an emergency in the time required, safely and in a controlled way;
Keep the recovery plans up to date.
-
IT Service Continuity Management Tasks
Options for eventuality planning: Do nothing; Manual conversion; Mutual agreement; Cold standby; Warm Standby; Hot Standby.
-
IT Service Continuity Management - Keywords
Risk: Risk refers to the possibility of suffering loss, damage,
disadvantage or destruction. It is thus the potential of undesirable negative effects arising from an event.
Cold standby: A cold standby solution for the case of a disaster exists if a
suitable failure location is provided for an eventuality, but no replacement plant is kept readily
Warm standby: In the case of a warm standby solution, bypass systems for
restarting IT services are available in a second location. However, after an event has occurred, the data will first have to be loaded before the service is available again.
Hot standby: In the case of a hot standby solution, the data on the bypass
environment is always kept up-to-date. In the case of an event, this system is immediately available for the user to continue operations.

Financial Management
-
Financial Management Objective
Financial management provides the basis for information on economical control, finance planning and cost accounting.
-
Financial Management Description
Financial management is responsible for the identification, calculation, monitoring and onward allocation of costs for the customer's contracted IT services.
By creating cost awareness, financial management can influence the behaviour of users and customers alike determining the true costs for providing IT services serves as the basis for financial management.
The pricing policy for the use of services by users must be fair and transparent.
Financial management also provides IT management with the basis for budget planning.
-
Financial Management Tasks
Budgeting (budget planning) Prepare cost targets and performance targets; Prepare budget cost estimates; Prepare investment and financing plans.
Accounting (target/performance accounting) Determine the true cost of services offered; Determine standard cost unit rates; Monitor expenditure, target/performance comparison; Cost type, cost centre and cost unit accounting.
Charging (costing; invoicing for services) Prepare invoicing bases for each service; Calculate transparent and understandable prices for services
rendered; Influence customer behaviour through pricing; Allocate costs onward based on actual services received; Prepare invoices.
-
Financial Management Keywords I
Costs: Actual costs, delimited physically and in time.
Expenditure: Accounting expenditure which includes undisclosed reserves.
Income: Actual income, delimited physically and in time.
Earnings: Accounting earnings which have not yet been delimited physically and in
time.
-
Financial Management Keywords II
Cost types: Cost-type accounting shows the costs which have arisen during a particular
period. All costs are classified according to cost types (e.g. cost of materials, personnel costs, cost of premises, hardware costs, or software costs) and accrued against the expenditure in financial accounting.
Cost centres: Cost-centre accounting shows in which department of the enterprise costs
have been incurred. For this reason, cost centres are formed, i.e. the enterprise is divided into sectors which provide uniform and calculable services. In cost-centre accounting, overheads are charged to the cost centres according to the principle of causation.
Cost unit: In job-order cost accounting, direct costs and overheads within a particular
period of time are charged to the individual cost units. Costing objects, such as IT services, which are listed in the service catalogue, are cost units.
-
Financial Management Keywords III
Prime costs: Prime costs or direct costs can be charged directly to the individual
service (cost unit). There is thus a directly measurable causal relationship between the creation of an IT service and the use of the service.
Overheads: In contrast to the above, overheads or indirect costs cannot be
charged directly to the individual service because they are incurred jointly for several services or because individual charging is too cumbersome and too expensive (e.g. maintenance costs of central server units).
Fixed costs: Fixed costs are costs which are not affected by fluctuations in output
and use over a particular period. They are incurred irrespective of the capacity utilisation rate and are thus constant (e.g. insurance premiums).
Variable costs: Variable costs react directly to fluctuations in output and in the
capacity utilisation rate (e.g. consumables such as printer cartridges).
-
Financial Management Keywords IV
Step costs: Step costs are fixed only for particular utilisation intervals; they
increase in a stepped shape (e.g. acquisition of a new server unit because the capacity of the old unit is no longer sufficient).
Costing: Costing or cost calculation serves the purpose of determining the
costs of individual IT services. In this way the costs for controlling business behaviour can be determined. Costing also provides the basis for pricing.
Break-even: In profitable pricing, a business enterprise attempts to indicate a
profit target from which the price can be derived. This is based on the prerequisite that apart from the desired profit, the business enterprise knows the total cost curve and has sufficient IT service capacity to satisfy the need (capacity management; demand management). The break-even analysis helps show the interrelationships between the variables mentioned. The break-even point represents the intersection between the cost curve and the income curve.
-
Financial Management Benefits
Cost finding helps to: Promote cost-consciousness and thus economic use of resources
within IT departments; Support the IT investment strategy; Assess change measures from the point of view of costs; Provide a basis for planning and budgeting; Make business decisions about each service provided; Set performance targets and monitor costs in the context of the
budget; Justify investments for new or improved services; Substantiate reasons for technical infrastructure renewal; Prioritise the use of resources.
Charges resulting are an accessory to: Monitoring services and investment plans; IT refinancing costs incurred; Influencing customer behaviour and thus overall cost reduction.
-
Financial Management Key Performance Indicators
Adherence to the budget; Degree of cost coverage; Liquidity; Process costs.
-
Security Management
-
Security Management Objective
Using security management, the data and infrastructures are to be protected so that Confidentiality is appropriately preserved; Integrity of information is ensured; Availability is ensured; Conducting a transaction is not denied; Obligations imposed by law, contractual
arrangements and supervisory bodies can be fulfilled.
-
Security Management Description
Security is a moving target and almost invariably difficult to plan and calculate because changes often originate from the outside in particular when understanding a necessary technical innovation.
However, the integrity as well as protection of customer and business data and of IT resources is crucial to the very survival of an enterprise.
Corporate management must therefore determine and document the security policy of the enterprise or the business sectors to be secured, set objectives and specify commitments for IT security.
Corporate management must further ensure that such objectives and commitments are understood at all levels and are implemented and maintained. In particular the following must be emphasised: Clearly determined security objectives; A defined area of application; Principles and codes of conduct to be implemented; Maintenance of the security process in all disciplines of service
management.
-
Security Management Tasks I
Determine a corporate strategy for handling infrastructure critical to the enterprise;
List all IT processes and components, taking into account interdependencies;
Determine and document respective criticality: Identify possible weak points; Assess the probability of damage occurring; Estimate the effects and extent of damage, taking into
account availability, confidentiality and integrity; Determine the criticality category: non-critical, critical,
or highly critical.
-
Security Management Tasks II
Verify the decision: Improve objectivity by comparisons and ranking tables; Assess the ability to influence sectors; Set priorities; if necessary, accept risk that some sectors might be
less well protected; Make a concluding assessment or management decision taking into
account possible consequences which are critical to the enterprise. Measures and concepts: Provide the necessary resources (finance, personnel, time, and
training); Safeguard and monitor basic protective measures for IT; Prepare a catalogue of measures to improve protection of the
systems rated as being highly critical; Prepare and extrapolate emergency plans; Implement and monitor measures and concepts (management
responsibility).
-
Security Management Keywords
Confidentiality Confidentiality means ensured protection against
disclosure of information without permission of the owner.
Integrity Integrity means ensured that protection against
modification of information by unauthorised persons is ensured.
Availability Supply facilities, which are critical to maintaining
business operations, are designed taking into account the use, risk of failure, necessary availability and confidentiality, and integrity of the data resulting from the protective requirements.
-
Security Management Benefits Increase in the level of security for data,
systems and applications; Prevention of data loss; Ensured data integrity; Guarantee of data confidentiality; Compliance with statutory obligations
concerning data protection; Increased customer confidence; Increased awareness of employees about
security issues.
-
Security Management Key Performance Indicators
Internal and external security audits; Number of intrusions detected, firewall
attacks, virus attacks etc.; Damage which occurs during security
infringements (image and repair); Process costs.
