3What is IT Service Management (ITSM)?
- ITSM is an approach that IT organizations can
utilize to design, build, integrate, manage, and
evolve quality IT services that - - Are customer-focused and process-driven
- Meet cost targets
- Enable achievement of performance targets as
defined in service level agreements (SLAs)
4Control Processes ????? ????????
- Do your system administrators spend too much time
fire-fighting? - Do you have a well documented change management
process that provides visibility and control
points for changes? - Are the largest percentage of problems caused by
changes made internally as opposed to externally?
- Can you quickly discover unauthorized or
undocumented changes? - Can you lock down production servers so no change
is allowed? - Can you map systems changes to a change request
or an authorized work order? - Do you schedule all system changes to fixed
maintenance windows to mitigate the risk of
changes? - Do you have an end-of-shift audit process, to
ensure that the Ops manager is handing over the
data center in the same that as he/she received
it?
5Release Processes ????? ????????
- Can you enforce a standard configuration build
across all of your devices? - Do you know precisely how many different
configurations you have in your environment? - Can you reliably rebuild servers that are in
production (i.e., "we can do bare-metal builds")?
- Do you perform change audits for all of your
production systems? - Are production and development systems clearly
separated? - How do ensure that the staging environment
matches the pre-production environment before
deploying into production? - Can you capture the known good state or "golden
build" as part of the release management process?
- Do have confidence that the deployed systems
match the golden build? - Do you have a library of automated build systems
for all critical devices (i.e., repeatable,
automated processes that can provision all
critical systems)?
6Resolution Processes ????? ????????
- Is change regardless of source the root cause of
most of your remediation efforts? - Is the longest part of your repair cycle spent
diagnosing what's wrong? - Can you quickly detect what changed on systems
during problem resolution? - Can you perform precision rollbacks when
undesired change is detected? - During remediation, can you see all authorized
work orders pertaining to a target system? - During remediation, can you see all previous work
tickets in order to learn what has caused
failures on your system in the past? - Do you track the change success rate?
- Do you have a process that maps all changes to a
valid business purpose or authorized work order? - Have you identified a set of change owner for all
critical systems? - Do you have a list of repeat offenders who
circumvent change management policies
7What is ITIL?
- ITIL - the IT Infrastructure Library
- A systematic, professional approach to the
management of IT service provision - Best practice, non-proprietary methodology
- The accepted de facto world standard in IT
Service Management - Applicable to organisations in the public and
private sector, large and small - ITIL currently has over 42,000 certified
consultants, primarily in Europe and Canada
8The Ethos and History of ITIL
- The British Government commissioned the CCTA
(Central Computer and Telecommunications Agency)
with the charter to save 1B over a 3 year
period. This was performed (in part) by the
development of best-practise processes (Prince-2
and ITIL). - On successful completion of the initial goal,
the British Government has now raised the bar on
the OGC to save 3B over a 3 year period with
the process implementation across the Government
sector. - Used by over 10,000 major corporations and
governments - OGC Office of Government Commerce
9Benefits of ITIL
- Cost effective improvement of IT services for all
stakeholders - A solid foundation for change
- based on proven principles
- Increased organisational performance
- IT services designed with users and customers
needs and goals in mind - A quality approach to IT service provision
- staff is more professional and more effective

Planning to Implement Service Management
The current OGC framework
13Service Support
The key business interfaces with the service
support processes are depicted below. The Service
Desk is a central point of contact for users to
report difficulties, make complaints or general
enquiries. The Service Desk can provide an
extended range of services allowing customers to
submit change requests, and establish maintenance
contracts, software licences, Service Level
Agreements (SLAs) and asset registers.
14Service Delivery
The key business interfaces with the service
delivery processes are depicted below. The
business is likely to have developed a close
relationship with Service Level Management during
the process of planning, coordinating, drafting,
agreeing Service Level Agreements (SLAs). The
SLAs provide the basis for managing the
relationship between the provider and the
customer.
15The Business Perspective
- Traditional organisations, whether they be in the
public or private sectors are confronted with a
new spectra the networked community or
economy, in which e-initiatives are driving a
significant number of IT investments, and
necessitating a jump in quality demands.
Businesses are becoming increasingly aware of the
importance of IT in not only supporting but also
enabling their operations. - To meet their demands, Business Managers and
specifically the 'informed' customer should
satisfy themselves that IT service providers are - focused on the quality of IT in terms of
reliability, availability, capacity and security - recognising the importance IT performance, as
outages and poor performance become more visible
(e.g. over the Internet) - able not only to supply but manage business
enabling technology and services. - able to demonstrate continuous service
improvements and value for money.
16Planning to Implement
People, Process and Technology The objective of
IT Service Management is to ensure that the IT
Services are aligned to the business needs. IT
Service Managers should recognise that it is
imperative that the IT Services they deliver
underpin the business processes. They should also
be aware of their increasingly important role to
act as an agent for change to facilitate business
transformation.
17Security Management
Security Management is the process that ensures
the proper access to services as defined by the
service agreements and prevents unauthorized
use. Security Management is not simply concerned
with system access controls, safeguarding
infrastructure and determining the vulnerability
of services. Security Management liase with the
business on policy and procedures, and assure the
business that services have a secure foundation,
so as to protect the business from embarrassing
and possibly detrimental security breaches.

24Incident Management
- Incident Management is the process focusing on
solving incidents and restoring services quickly.
25Responsibilities of Incident Management
- Accepting and recording incidents whether they
are found by a user, management system, or IT
personnel. Each incident is recorded with a
tracking number, basic yet detailed information
about the incident (such as time, affected users,
affected service, etc), and supplemental
information from other sources. - Incident Management also alerts other impacted
users for high impact incidents. - Classifying incidents with a category (type of
incident), priority based on urgency and impact,
related services, time to repair requirements of
the SLA, and incident identification. - Closing incidents by verifying the solution with
the person who reported the incident.
26Responsibilities of Incident Management
- Matching new and previous incidents looking for a
workaround used for a similar incident in the
past. - Investigating and diagnosing incidents to find a
solution. - Resolving and recovering incidents including
submitting Request for Changes (RFCs) to the
Change Management process. - Monitoring and tracking incidents to keep users
and other ITIL processes up to date with any
changes.
27Incident Management
- Responsible for finding Resolutions and
Work-arounds
28Problem Management
- Problem Management is the process focusing on
solving root cause problems to prevent future
incidents..
29Problem Management
- Problem control to identify problems and diagnose
them to find the root cause. This step includes
recording problem details including the related
incidents. - Error control to monitor and fix known errors
where appropriate based on SLAs, costs to fix,
and impact. - Proactive Problem Management focusing on quality
of the IT Infrastructure using trend analysis to
find potential problems before incidents occur. - Providing information regarding known errors and
workarounds to other ITIL processes.
30Change Management
- Change Management is the process that controls
the implementation of changes in the
infrastructure. - The goal of change management is to manage the
change process so changes can be done quickly and
with little impact on the services thereby
limiting the incidents resulting from the change. - Not every change is an improvement, but every
improvement is a change
31The responsibilities of Change Management
- Recording all Requests for Change (RFCs). An RFC
is submitted for every non-standard change. A
well known and clearly defined modification, such
as a password reset, can be handled with a
Service Request to the Service Desk. - Accepting RFCs to ensure all the required
information to make decisions is included. If the
required information is not included, the RFC is
rejected and must be resubmitted. - Classification of the RFCs after they are
accepted where a priority and category (minor,
substantial, or major impact) is assigned.

34The responsibilities of Change Management
- Planning of changes to ensure they are
implemented in the required timeframe with the
proper approvals and understanding the true
impact and required resources. - Coordination of the change with the appropriate
IT personnel to make the change. Making the
change includes building, testing, and
implementing the change. - Evaluation of the change after it is implemented
to determine if it met the required objective, if
users are satisfied, if there were side effects
of the change, and if costs and resources were
within budget. - Implementing urgent changes where there is not
time to follow the full process. In this case,
the evaluation and other steps must be completed
following the change in order to ensure
traceability of the change.
35Release Management
- Release management is the process that controls
the rollout of new releases in the infrastructure.
36Responsibilities of Release Management
- Release policy and planning including details
from figuring out all the dependencies,
coordination of the release with schedules and
communication plans, determining the testing
plans, and other details related to the release. - Design, building, and configuration of the
release. This includes testing the release in a
lab environment and creating full documentation
on how to recreate the configuration help ensure
a successful implementation in production. This
activity also includes creating a back-out plan
in case there are problems during implementation
that require the release to be aborted and to
restore the previous environment.
37Responsibilities of Release Management
- Testing and release acceptance includes
functional testing by a subsection of the users
and operational testing by IT. - Implementation planning augments the release
planning by including all the details for task
schedules and required resources, all items that
must be changed, communicating to all affected
people, etc. Releases are either done in one full
release or in stages.
38Responsibilities of Release Management
- Communication, preparation and training for all
parties who communicate with customers and users
to ensure they can communicate the right
information. Further, changes to all SLAs, OLAs,
and Underpinning Contracts must be communicated
as early as possible prior to the release. - Release distribution and installation includes
the actual rollout. Rollout includes purchasing
the appropriate equipment, implementing it,
ensuring the Configuration Management DB is
updated, and verifying a successful
implementation.
39Release Management Objectives
- Deliver systems that are correctly configured and
built first time e.g. 99 of target - Repeatable, consistent process that is cost
effective, responsive and flexible - Everyone knows what is happening when
- Accurate updates are fed back to configuration
management - Can do OFTEN QUICKLY!
- Maintain quality

46Configuration Management
- Configuration Management is the process that
keeps all required information about services,
service components, relationships, and other
items accurate and up to date. - The information includes details about each
specific component (Configuration Item - CI), as
well as the relationships between each CI, and is
stored in the Configuration Management Database
(CMDB).

48Responsibilities of Configuration Management
- Planning to define the strategy, process, and
objectives of Configuration Management. - Identification where the data models are defined
to record the appropriate information on each CI
and the relationships with other CIs. - It also includes defining the methods of adding
new CIs and updating existing CIs to ensure the
CMDB is always up to date and has the appropriate
information. - Control to ensure only authorized changes and
additions are made to the CMDB. This requires
appropriate approval and documentation such as an
approved Request for Change in order to make any
changes to the CIs.
49Responsibilities of Configuration Management
- Status Monitoring to indicate the status
lifecycle of each CI from under development,
test, stock, live use, to phased out. - Verification to audit the infrastructure and
verify the CIs existence and actual information
to ensure the CMDB is correct. - Reporting to provide information on the CIs and
their relationships to the other ITIL processes.

57Service Delivery
- Service Level Management
- Availability Management
- Capacity Management
- IT Service Continuity Management
- Financial Management for IT Services
58Service Level Management
- Service Level Management is the process that
defines and implements clear agreements for
service delivery between the customers and the IT
organization. - It includes everything from negotiating with the
customers, defining the service with regard to
the customer requirements, managing and measuring
the service and improving quality over time all
within an acceptable cost structure.
59Other key SLM terms
- SLA - A Service Level Agreement is an agreement
between IT and the user community which defines
the responsibilities of all participating parties
and which binds IT Service Management to provide
a particular service of a specific agreed-upon
quality and quantity for a specific duration, and
constrains the demands users may place upon the
service to those agreed-upon limits defined by
the contract. - SLO - A Service Level Objective is an
agreed-upon, measurable service metric target
between the IT organization and one or more of
its customer communities, applied to the services
provided to those communities.
60Other key SLM terms
- OLA - An Operational Level Agreement is an
internal IT agreement between the Service Manager
and an INTERNAL service provider (e.g., Network
Support, Help Desk, etc.) that defines the
responsibilities of the service provider to
deliver a particular service component (e.g.,
network, support, database, etc.) of a specific
agreed-upon quality and quantity for a specific
duration. The OLA should include the technical
details and metrics required to support a
specific SLA. - UC An Underpinning Contract is a contract that
binds IT (on behalf of the business) and one or
more EXTERNAL vendor suppliers or that defines
the responsibilities of the vendor to deliver a
particular service component (e.g., hardware,
application/ system support, etc.) at a specific
agreed-upon quality and quantity for a specific
duration.
61Responsibilities of Service Level Management
- Developing a Service Catalog to provide details
of services offered written in language that can
be easily understood by customers. - Identifying customer needs includes
understanding their business processes and
requirements to enable creation of the proper
services and SLAs. - Defining services to meet the needs identified
with the customer. The services are documented in
the Service Level Requirements, in a
non-technical language that can be understood by
the customer. Specification Sheets including both
the detailed customer requirements and how this
will impact the IT Organization are also
developed.
62Responsibilities of Service Level Management
- Implementing, monitoring, and reporting on the
services on a regular basis. - Creating Service Improvement Plans (SIPs) to
continuously improve IT Services helping both the
provider and the customer remain competitive.
63Responsibilities of Service Level Management
- Creating contracts required for each service
- Service Level Agreements between the provider and
customer. - Operational Level Agreements between internal
organizations required to deliver the service
levels. - Underpinning Contracts between the provider and
any external suppliers required to deliver the
service at the guaranteed levels.
64Service Level Management Process
65SLM Process
Phase 1 INITIATE
Phase 3 PERFORM
Phase 2 NEGOTIATE
Phase 4 MONITOR REVIEW
Phase 5 COMPLETE
Close SLA
66Phase 1 Initiate
The Initiate phase involves assessing the
customer situation and understanding the
customers issues. This step defines
what information is required to initiate the
development of SLOs. This phase is comprised of
the following activities
- Identify executive sponsors, stakeholders
- Educate IT and customer on key components of
Service Management, and - gather initial data
- Understand business drivers, metrics and ROI
- Define customers, communities, and users
- Determine customer needs (and wants)
- Evaluate current customer - IT relationship
- Determine customers perception of current IT
service delivery - Determine services required based on customers
operational needs - Define customer timetable
- Identify customer issues
- Identify special requirements (e.g., development
systems, etc.)
67Phase 2 Negotiate
Negotiations occur between IT and the customer on
what services are required. This phase defines
the areas of service that can (or cannot) be
negotiated in establishing an SLO. This phase
contains the following activities
- Determine the services that should (or should
not) be negotiated I.e., determine - how desired service levels can be met and
maintained - Calculate the cost of providing the service
levels - Determine accountability (customer and IT)
- Identify service requirements and prioritize
them - Conduct a cost/benefit analysis
- Negotiate appropriate SLOs based on cost/benefit
analysis - Present outcomes and approve next steps
68Phase 3 Perform
The Perform phase involves the design and
implementation of the SLO infrastructure that
will deliver the SLOs and allow the creation of
the SLA. This phase contains the following
activities
Developing the SLO Infrastructure
- Define design objectives, requirements, solution
models that support SLOs - Develop/update technical infrastructure to
support SLOs - Develop/update IT processes to support SLOs
- Define how services can be measured by
identifying measurement parameters - (metrics)
Write the SLA/OLA
- Define the methodology required to facilitate
the measurement of services (incorporating tools
as necessary, to support the collection and
reporting of service level information) - Define remedial actions where required
- Identify IT operational metrics and IT process
metrics that must be monitored - Identify process for incident and problem
management - Identify customer training
69Phase 4 Monitor Review
This phase monitors service levels, creates
service level reports, reviews the customer
services provided and modifies an existing SLA to
incorporate new services or remove old services.
This phase contains the following activities
- Monitor service levels
- Report service levels
- Review SLAs. Over a period of time, a customers
business requirements may - change and the service levels defined earlier
in the negotiation phase may no - longer be suitable
- Modify SLAs
- Evaluate the customers perception of the
service being provided (e.g., user - satisfaction reviews/surveys)
70Phase 5 Complete
An SLA exists for a specific time period agreed
to by the customer and IT. When an SLA is nearing
the end of its life, a formal review of the SLA
is conducted with the user community and IT.
Metrics are reviewed and action plans are
established to help improve IT processes and
customer relationships, if required. This phase
contains the following activities
Procedures for terminating an SLA. Procedures
would include
- Steps for handing the support of an application
back to the customer - Steps for notifying the relevant people
regarding changes in the support structure
71Financial Management for IT Services
- The goal of Financial Management for IT Services
is to enable IT to provide services
cost-effectively through the financial management
of IT resources required to deliver the service.
This includes budgeting, accounting, and
charging. Through this process both IT
organizations and customers alike become more
aware of the true costs of delivering the
services, allowing them to make better business
decisions.
72Financial Management for IT Services
- Budgeting is based on planning for customers'
needs and determining the cost associated with
delivery of services to the customers. Accounting
consists of tracking the expenditures of IT. It
specifically tracks the cost by customer,
service, etc. Without Budgeting and Accounting,
it becomes difficult to make business decisions
that balance cost of services with service
quality.
73Financial Management for IT Services
- Charging includes all things required to bill the
customer from the objectives to the actual
calculation methods. The advantage of charging,
whether to internal customers or to external
customers, based on the quality of the service is
that it improves the provider/customer
relationship. It opens up negotiations regarding
what will be provided for what price and allows
customers and providers to make informed business
decisions based on cost vs. quality.

75Cost-by-Service Cycle
76Capacity Management
- Capacity Management is the process that optimally
manages capacity to meet the service requirements
at an acceptable cost. - The goal of Capacity Management is to provide
adequate capacity to meet the SLAs in a cost
effective manner. In order to reach this goal it
is important to - Avoid overspending on capacity that goes
unused. - Avoid guessing on what will meet the
service needs. - Plan for upcoming needs enabling better
purchase decisions
77Objective of ITIL Capacity Management
- To ensure that cost justifiable capacity
- always exists
- Hardware
- Networking Equipment (LANs, WANs, bridges,
routers) - Peripherals (bulk storage devices, printers)
- Software (OS, network SW, purchase/in-house)
- HR
- is matched to the current and future business
requirements
78Capacity Management Sub Process A
- Business Capacity Management, taking the
customers business plans into account to predict
future capacity needs. After understanding the
customer business needs, providers typically
determine the capacity required to support new or
modified applications by using models and
simulations to determine the requirements
79Capacity Management Sub Process B
- Service Capacity Management to ensure SLAs can be
met based on current and peak loads on the
infrastructure. This is done through monitoring
and analyzing performance of the monitored
services and comparing to the resource load
determined in Resource Capacity Management.
80Capacity Management Sub Process C
- Resource Capacity Management to understand the
use of the IT infrastructure by monitoring trends
on the resources needed to provide the services.
This sub-process monitors metrics such as CPU
utilization, disk space, bandwidth utilization,
etc.
