ITIL History  In the late 1980’s, the British govt. asked the Central Computer and Telecommunications Agency (CCTA) to structure the IT organisations of the British government agencies.

 This resulted in the IT Infrastructure Library, a library of books describing best practices in IT management, and a detailed approach for the implementation of these best practices.

 The aims of the CCTA in developing the IT Infrastructure Library were: – – – –

What is ITIL?  ITIL is a compilation of best practices in IT Service Management, developed by the OGC (Office of Govt. Commerce) and supported by publications, qualifications and an international user group.

 ITIL defines the organisational structure and skill requirements of an information technology organisation and a set of standard operational management procedures to allow the organisation to manage an IT operation and associated IT infrastructure.

 ITIL does not set in stone every action you should do on a day-to-day basis as that is something which differs from organisation to organisation. Instead, it allows the IT Infrastructure Library to be utilised within organisations with existing methods and activities in Service Management.

 IT Service Management is concerned with delivering and supporting IT services that are appropriate to the business requirements of the organisation. 4

The Service Support set  Service Desk – Single point of contact between service providers and Users, on a day-to-day basis – Focal point for reporting Incidents and making service requests – Keeps Users informed of service events, actions and opportunities that are likely to impact their ability to pursue their day-to-day activities

 Incident Management – Restore normal service operations as quickly as possible – Should interface closely with Problem Management, Change management and the Service Desk – Incident priorities and escalation procedures need to be agreed as part of the Service Level Management process and documented in the SLAs

20

Kashif Baig - Service Management, Bangalore

ITIL Foundations Certification Course

The Service Support set  Problem Management – Prevent and minimize the adverse effect on the business of errors in the IT Infrastructure – Performs RCAs to establish the root causes of Problems – Requires the accurate and comprehensive recording of Incidents in order to identify effectively and efficiently the cause of the Incidents and trends – Liaises closely with Availability Management process to identify these trends and instigate remedial action

 Change Management – Ensure standardized methods and procedures are used for efficient, prompt and authorized handling of all changes in the IT Infrastructure – Close relationship with Configuration Management and Release Management

21

Kashif Baig - Service Management, Bangalore

Service Desk  Service Desk acts as the Single Point of Contact (SPOC) between the users and the IT Services Organization

 ITIL defines customers and users : – Customers : People (generally senior managers) who commission, pay for and own the IT Services, sometimes referred to as "the business" – Users : People who use the services on a day-to-day basis

24

Kashif Baig - Service Management, Bangalore

ITIL Foundations Certification Course

Service Desk (contd..)  The primary functions of the Service Desk are : – Incident Control : life cycle management of all Service Requests – Communication : keeping the customer informed of progress and advising on workarounds

 It handles all incoming calls and only directs them through to the second or third tier support when necessary : – for the customer, the advantage is that they don’t have to ring around searching for the right person to solve their problem – for IT personnel, it means that they only have to deal with issues that are related to their skills or area of responsibility

Note:- The Service Desk is not a process - it is a FUNCTION

25

Kashif Baig - Service Management, Bangalore

ITIL Foundations Certification Course

Service Desk - Types  The Service Desk function is known under various names :

– Call Centre • main emphasis on professionally handling large call volumes of telephonebased transactions

– HelpDesk • manage, co-ordinate and resolve incidents as quickly as possible

– Service Desk • not only handles incidents, problems and questions but also provides an interface for other activities such as change requests, maintenance contracts, software licenses, Service Level Management, Configuration Management, Availability Management, Financial Management and IT Services Continuity Management 26

Kashif Baig - Service Management, Bangalore

ITIL Foundations Certification Course

Service Desk - Types  Many Call Centres and HelpDesks naturally evolve into Service Desks to improve and extend overall service to the Customers and the Business

 All three functions share common characteristics : – they represent the service provider to the Customer and the User (internal or external) – they operate on the principle that customer satisfaction and perception is critical – they depend on blending people, processes and technology to deliver a service

27

Kashif Baig - Service Management, Bangalore

ITIL Foundations Certification Course

Service Desk - Structures  The three types of structure that can be considered are :

– Local Service Desk • to meet local business needs - is practical only until multiple locations requiring support services are involved

– Central Service Desk • for organisations having multiple locations - reduces operational costs and improves usage of available resources

– Virtual Service Desk • for organisations having multi-country locations - can be situated and accessed from anywhere in the world due to advances in network performance and telecommunications • reduces operational costs and improves usage of available resources

Incident Management  An Incident is defined as “ any event which is not part of the standard operation of a service and which causes or may cause, an interruption to, or a reduction in, the quality of that service “

 The primary goal of Incident Management is to restore normal service operations as quickly as possible with the least possible impact on business operations, at a cost-effective price, thus ensuring that the optimum levels of service quality and availability are maintained

 In lay-man terms, Incident Management is similar to “fire-fighting”  Inputs for Incident Management mostly come from users (through the Service Desk), but can have other sources as well like Automatic Detection Systems or Release Management

45

Kashif Baig - Service Management, Bangalore

ITIL Foundations Certification Course

Incident Management - Incident Classification  Prioritising The priority with which Incidents need to be resolved and therefore the amount of effort put into the resolution of and recovery from Incidents, will depend upon : – The impact on the business – The urgency with which a resolution/work-around is needed – The size, scope and complexity of the Incident – The resources available for coping in the meantime and for correcting the fault

46

Kashif Baig - Service Management, Bangalore

ITIL Foundations Certification Course

Incident Management - Incident Classification  All incidents are categorised in order to establish appropriate priorities and resolution lead times

 To facilitate lead-times of incident resolution, accurate classification and sufficient registration is imperative

 The criteria to consider when assigning priority are: – Impact : To what extent an incident results in a deviation from the normal service level; aspects are the number of users and the service concerned – Urgency : To what extent the solution of an incident can be postponed

Priority = Impact x Urgency

Problem Management

60



A problem is a “condition identified from multiple incidents exhibiting common symptoms, or from a single significant incident, indicative of a single error, for which the cause is unknown.”



The goal of Problem Management is to minimize the adverse impact of incidents and problems on the business caused by errors within the IT Infrastructure, and to prevent reoccurrence of incidents related to these errors.



While Incident Management focuses on quick resolution of incidents, Problem Management analyses the root cause of the incidents.

Kashif Baig - Service Management, Bangalore

ITIL Foundations Certification Course

Problem Management (contd..) 

Problem Definition Many criteria can be used to define a Problem including : – A number of related incidents – Incident closed via work-around (temporary fix) – Major incident – Information from third parties

61

Kashif Baig - Service Management, Bangalore

ITIL Foundations Certification Course

Problem Management (contd..) Problem Management Terminology – Problem • The unknown root cause of one or more incidents (not necessarily – or often – solved at the time the incident is closed) – Error • A condition that exists after the successful diagnosis of the root cause of a Problem – Known Error • Error + solution and/or workaround has been found – Known Error DataBase (KEDB) • Repository of known errors for the benefit and utilisation of Incident Management 62

Kashif Baig - Service Management, Bangalore

ITIL Foundations Certification Course

Problem Management (contd..)  Problems can be identified from incidents. When a problem is defined, diagnosis takes place to find the root cause of the problem, and then a change request is entered to correct the problem

63

Kashif Baig - Service Management, Bangalore

ITIL Foundations Certification Course

Problem Management (contd..) 

64

The "Funnel Effect" is shown below - multiple incidents are usually, after investigation, re-classified as a smaller number of problems, which are also reanalyzed and (usually) reclassified as yet a smaller number of known errors, which usually, after further investigation, end up resulting in a smaller number of RFCs

Kashif Baig - Service Management, Bangalore

ITIL Foundations Certification Course

Problem Management (contd..) 

The primary functions of Problem Management are : – Problem Control: identifying the real underlying causes of incidents in order to prevent future reoccurrences

65

Kashif Baig - Service Management, Bangalore

ITIL Foundations Certification Course

Problem Management (contd..) – Error Control : the processes involved in successful correction of Known Errors. The objective is to change IT components to remove Known Errors affecting the IT infrastructure and thus to prevent any recurrences of incidents

66

Kashif Baig - Service Management, Bangalore

ITIL Foundations Certification Course

Problem Management (contd..) Investigation and Diagnosis of Problems The various methods include : – Ishikawa diagrams – Kepner and Tregoe – Brainstorming sessions – Voting – Flowcharts – Common sense – Deduction

67

Kashif Baig - Service Management, Bangalore

ITIL Foundations Certification Course

Problem Management (contd..)  Proactive Problem Management comprises of : – Trend Analysis • Identifying ‘fragile’ components of an IT Infrastructure and investigate the reasons for this ‘fragility’ – Targeting preventive actions • Trend analysis can lead to the identification of faults in the IT Infrastructure which can then be analysed and corrected via Problem and Error Control – Improving procedures – Research other sources of knowledge about known errors

68

69

Kashif Baig - Service Management, Bangalore

ITIL Foundations Certification Course

Problem Management (contd..) Known Error DataBase (KEDB) :

Problem Management reduces a Problem into an Error after it has successfully identified the root cause of the Problem. When a solution or a work-around is identified for this Error, it is transformed into a Known Error The Known Error DataBase is a repository containing all these Known Errors. The KEDB is essentially for the utilisation of the Incident Management process and to prevent Incidents from becoming Problems

A Release consists of the new or changed software and/or hardware required to implement approved Changes



Releases are categorised as : – Major software Releases and hardware upgrades, normally containing large areas of new functionality, some of which may make intervening fixes to Problems redundant. A major upgrade or Release usually supersedes all preceding minor upgrades, Releases and emergency fixes – Minor software Releases and hardware upgrades, normally containing small enhancements and fixes, some of which may have already been issued as emergency fixes. A minor upgrade or Release usually supersedes all preceding emergency fixes – Emergency software and hardware fixes, normally containing the corrections to a small number of known Problems
