ITSM 3

Chapter 3 ITIL – The IT Service Lifecycle

Information Technology Infrastructure Library

  • The ITIL is a set of concepts and practices for Information Technology Services Management(ITSM), Information Technology development and IT operations
  • ITIL gives detailed descriptions of a number of important IT practices and provides comprehensive checklist, tasks and procedures that any IT organization can tailor to its needs

ITIL – Basic Concepts

  • Good practice – ITIL is presented as a good practice or correct method, an approach that has proven itself in practice
  • Service – is a means of delivering value to customer by facilitating outcomes the customer want to achieve without the ownership of specific costs or risks
  • Service management – a set of specialized organizational capabilities for providing value to customers in the form of success.
    • Some principles of Service Management
    • Specialization & co-ordination – the goal of service management is to make capabilities and resources available through services that are useful and acceptable to the customer
    • Including quality, costs and risks
    • Service provider takes the weight of responsibilities off the customer’s so they can focus on core business
  • Agency principle – may be consultants, advisors or service providers, act as intermediary between service providers and customers
  • Value – is the core of service concept, from the customer’s perspective consist of two core components, utility and warranty, what the customer receives and how it is provided
  • Encapsulation – customer interest focuses on the value of use, and spared from any technical details and structure complexity.
  • The encapsulation principle is focused on hiding what the customer does not need and showing what is valuable and useful to the customer
  • Systems – is a group of interacting, interrelating or interdependent components that form a unified whole, operating together for a common purpose
  • Service management – is a set of specialized organizational capabilities for providing value to customers in the form of services
  • Function – is a subdivision of an organization that is specialized in fulfilling a specific type of work, and is responsible for specific end results
  • Process – is a structured set of activities designed to accomplish a defined objective, result in a goal oriented change and utilize feedback for self enhancing and self corrective actions, with measurable, specific results

The Service Lifecycle

  • ITIL version 3 approaches service management from the lifecycle of a service.
  • It is an organization model providing insight into:
    • The way service management is structured
    • The way the various components are linked to each other
    • The impact that changes in one component will have on other system components and on the entire system
  • Service strategy – the phase of designing, developing, and implementing service management as a strategic resource
  • Service design – design phase of developing appropriate IT services, including architecture, processes, policy and documents
  • Service transition – the phase of developing and improving capabilities for the transition of new and modified services to production
  • Service operation – achieving effectiveness and efficiency in providing and supporting services
  • Continual service improvement – the phase of creating and maintaining the value for the customer by design improvement and service introduction and operation

Service Strategy

  • Guidelines that will help in setting customer- and market-oriented goals and expectations.
  • Helps in identifying, selecting and prioritizing opportunities(distinguishing capabilities).
  • A clear service strategy helps to ensure that an organization is equipped to manage costs and risks within the Service Portfolios.
  • Help to maintain the link between policies and tactics.
  • Goal – to identify the competition and to compete with them by distinguishing oneself from the rest and by delivering superior performance.
  • The 4 P’s of service strategy- Henry Mintzberg
    • Perspective – have a clear vision and focus
    • Position – take a clearly defined stand
    • Plan – form a precise notion of how the organization should develop itself
    • Pattern – maintain consistency in decisions and actions

Perspective

  • Strategy is a perspective because it provides the vision and focus of an organization.
  • Defines the convictions, value and goals that govern the behavior of the entire organization
  • A strategic perspective determines the direction through which the service provider can achieve its objectives
  • Test – Are they clear and memorable, suitable for promoting and conducting activities, do they establish the boundaries within which people are free to experiment

Position

  • Strategy as position defines the distinguishing characteristics of the service provider in the eyes of the customer
  • Based on diversity, a limited catalogue of services, but with depth that diverse customers with similar needs can be served
  • Based on needs, a broad catalogue of services that delivers to a specific type of customer
  • Based on accessibility, possibility to deliver services to customers with specific needs such as location, scale or structure

Plan

  • Strategy as plan focuses on the organization’s action plan in a competitive market – how an organization handles a development
  • Service management is a co-ordinated set of plans through which service providers plan and implement service strategies

Pattern

  • Strategy as pattern represents an organization’s procedures.
  • As a consequence of the perspective, position and plan of the strategy, characteristic patterns are created and lead to recurring successes

To form the Mission and Objectives

  • What kind of services must we offer and to whom?
  • How do we stand out above the competition?
  • How can we justify strategic investments?
  • How can we actually create value for the customer and our stakeholders?
  • How can we efficiently allocate resources in a Service Portfolio?
  • How can we use financial management to ensure insight and control over value creation?

Service Value

  • ITIL uses two basic concepts for the value of a service
  • Utility – fitness for purpose. The attributes of the service that have a positive effect on the performance of activities, objects and tasks with specific results. Possible increase in profits.
  • Warranty – fitness for use. Availability and reliability in continuity and security. Decline in possible loses
  • The utility is what the customer receives, and warranty affirms how it will be delivered

Communicating Utility and Warranty

  • Warranty guarantees the utility of a service
  • Availability – services available according to agreed conditions
  • Capacity – affects the utility of most services
  • Continuity – service supports the business even during times of difficulty
  • Security – can make use of the service safely and securely

Service Structure

  • Who are the participants in the service
  • What are the patterns in exchanges and transactions
  • What is the impact or what are the products to be delivered from each transaction and each participant
  • What is the best way to generate value?

Service Assets

  • Risk management – ensures that there are processes in place that are focused on monitoring risks

Generic Framework for Risk Management

Types of Risks

  • Contract risks – service provider makes it impossible to satisfy the contractual agreements are strategic risks. Coordination throughout the entire lifecycle is necessary in order to manage this risk
  • Design risks – service achieve undesirable results, a performance risk, a result of bad design
  • Operational risks – for the business units and for the service units
  • Market risks – Effective service management reduces the competitive risk.
  • Market risks can be reduced through
    • Differentiation , provide assets that are scarce and not commonly provided
    • Consolidation of the demand reduces the financial risks

Service Design

  • To satisfy the needs and demands of the business, the design of effective and efficient IT services is a process of balancing the functionality, available resources and available time

  • Based on requirements, the capacity management team model these requirements within the existing infrastructure
  • If new infrastructure or more support needed, financial management involved
  • Before the implementation, a Business Impact Analysis(BIA) and risk assessment performed
  • This provides valuable information for IT Service Continuity Management(ITSCM), availability management and capacity management
  • The service desk must be brought up to speed regarding the new service delivery
  • Service Transition can make a plan for the implementation of the service
  • Supplier management must be involved if there are purchases to be made
