Today's note - ITIL v3 2011 Foundation - Service Management as a good practice

Today, I am attending ITIL v3 2011 course. While it is hot, for my own benefit, Iwant to take notes what I've learned today for my reference in exam.

Why IT Service Management is Needed?

  • Higher IT service quality is always required while fewer resources are available
    • Users are not interested in the processes / technology, rather they just need to utilize the service to achieve business goals
    • As users are usually not directly responsible for the costs of IT services, they would endlessly request more and more IT services with higher and higher standards / quality
  • Changes to business and technology happen continually that would affect IT systems and processes
    • Nowadays, IT services are increasingly provided as business services to the external customers (e.g. in the past, bank customers would need to go to a local bank to request a transaction with the bank teller who would make use of the IT system to retrieve the account and record the transaction; nowadays, customers would directly make transaction online or in ATMs where the IT services are directly used by the customers)
  • The need to balance IT services request and quality with available resources to deliver the maximum value to the business -> IT service management

What is IT Service Management?

IT Service

  • [definition] A service is a means of delivering value to customers by facilitating outcomes customers want to achieve without the ownership of specific costs and risks
    • e.g. Email service: business users just make use of email service for communication needs, the management, cost and risks (e.g. security, hardware, virus, etc.) are not their concerns
    • outcome is the result of carrying out an activity, including intended and actual results
    • two types of customers: internal (within the same organization) and external (outside the organization)
    • external services provide a more direct and visible contribution to the business outcome than internal services
  • [definition] IT Service – A service provided by an IT service provider. An IT service is made up of a combination of information technologypeople and processes. A customer-facing IT service directly supports the business processes of one or more customers and its service level targets should be defined in a service level agreement. Other IT services, called supporting services, are not directly used by the business but are required by the service provider to deliver customer-facing services.
  • IT Services consist of taking care the design, implementation and maintenance of all the components that are required to fulfill a business objective for the users (i.e. IT and business integration, not just IT and business alignment)
  • Values of IT services
    • Create values for the business by supporting business processes
    • Create values for end customers
    • Reduce costs / increase productivity (enhance performance)
    • Manage costs / risks / issues more effectively
    • Reduce / remove constraints (e.g. not enough bandwidth)
    • Facilitate achievement of outcomes (e.g. students registering for a class)
  • Customer Satisfaction is at the core of judgment of the quality of the services. Service costs (total cost of ownership (TOC), return on investment (ROI) or overall cost) will be a major factor to be considered by the customers.
  • Types of services – according to the value for customers
    • Core Services: required directly by customers to deliver an intended outcome
    • Enabling Services: needed to ensure core services can be delivered successfully, not visible to customers
    • Enhancing Services: created to add features / values to the customers, not essential
  • Types of IT services – according to the customer types
    • Supporting Services (infrastructure services): not directly visible to customers, managed with operation level agreements
    • Internal Customerfacing Services: enable internal customers to carry out its business process, managed with service level agreements
    • External Customerfacing Services: used by the external customers, can be the business process itself, managed with contracts
  • service package is a collection of two or more [generic] services that have been combined to offer a solution to a specific type of customer need or to underpin specific business outcomes. A service package may consists of any types of services. The generic services used in this way can achieve economy of scale.
  • In case if there is a need for giving options on warranty and/or utility for components of a service package, different service level packages can be offered as service options.

Stakeholders

  • [definition] Stakeholders are individuals or groups that have an interest in an organization, service, or project and are potentially interested or engaged in the activities, resources, targets, or deliverables from service management.
    • Internal stakeholders: within the service provider organization
    • External stakeholders: outside customers, users, suppliers (vendors, network providers)
  • [definition] Service providers are organizations supplying services to one or more internal or external customers.

IT Service Management

  • [definition] Service Management is a set of specialized organizational capabilities for providing value to customers in the form of services.
    • Capabilities: functions and processes for managing services over a lifecycle
    • Specialized: in strategy, design, transition, operation, and continual improvement
    • The capabilities represent a service organization’s capacity, competency, and confidence for action.The act of transforming resources into valuable services is at the core of service management. Without these capabilities, a service organization is merely a bundle of resources that by itself has relatively low intrinsic value for customers.
  • [definition] IT Service Management: The implementation and management of quality IT services that meet the needs of the business. IT service management is performed by IT service providers (to internal or external customers) through an appropriate mix of people, process and information technology.
    • Make use of best practices (a set of generic (high level) guidelines based on the successful experiences of a number of organizations) in service management, adapt and apply for the business to save cost and improve quality
    • [definition] Good practice could be either an application of best practice, or an input into best practice
  • Types of IT Service Providers
    • Type I: Internal Service Provider – service providers located within the business unit, maybe several internal service providers within an organization
    • Type II: Shared Services Unit – supports several business units, e.g. centralized IT department
    • Type III: External Service Provider – delivers services to external customers
  • Suppliers vs Providers
    • suppliers only provide an element of the service which is not visible to the customer

Process

  • process is a set of activities designed to turn input(s) into output(s) to accomplish a specificobjective (need to be measurable, expressing in terms business benefits for business goals), often including feedback (report, measurements (metrics)) from the output to be used for process improvements
  • Processes may include roles, responsibilities, tools and management controls (actions, dependencies, and sequence) and are supported by the enablers (resources and capabilities).
  • The process is considered effective if all the objectives of the output are met.
  • Each process is owned by a process owner responsible for the process and improvement, ensuring the process meets the defined objectives
  • Once defined, processes need to be documented and controlled (repeatable and manageable)
  • Process Characteristics:
    • Measurable (performance based e.g. cost, quality, productivity, duration)
    • Deliver specific identifiable and countable results
    • Meet the expectations of the customers / stakeholders
    • Respond to specific events (called triggers)

Business Process, IT Process and IT Service

  • IT teams provide the service to enable the business process to be automated.
  • IT team will need to take reference to the ITIL best practice of IT processes to deal with a particular business process
  • Benefits of Process Automation with IT Service:
    • Capacity Management – Improve quality, i.e. can respond to variation in demand, less time restrictions
    • Optimization – handle complex tasks better
    • Measurement – for improvement as human factor is ruled out
    • Reduce costs (users can self-serve) and risks (human errors)
    • Knowledge Capture – reduce variations as the process is well studied and documented
  • The tasks should be well studied and only “simple” and routine tasks with recognizable patterns can be automated
  • Areas of service management ideal for automation:
    • design and modeling (for project and forecasting)
    • service catalog (capture demand for services)
    • pattern recognition and analysis
    • classification, prioritizing and routing
    • detection and monitoring
    • routine service requests

Functions and Roles

  • [definition] Function: A team or group of people and the tools they use (resources) to carry out one or more processes or activities
    • Functions are self-contained units responsible to carry out the tasks to create specific outcomes
    • provide structure and stability to the organization
    • have their own body of knowledge accumulated through experience
    • e.g. technical management, application management, operations management functions, service desk
  • [definition] Role: A set of responsibilities, activities and authorities granted to a person or team
    • triggers to play the role are determined by processes (by the line-manager)
    • one person/team can take up several roles in different context
    • e.g. change management role, capacity management role
  • Defined roles in ITIL:
    • Group – a number of people performing similar activities, not formal structure
    • Team – a more formal structure for people working together with a common objective
    • Department – a formal organizational structure with a hierarchical structure
    • Division – a number of departments forming a self-contained unit

Why Information Technology Infrastructure Library (ITIL)?

ITIL is recognized as a world-wide best-practice approach for delivering IT services and IT service management by focusing on the processes, functions, and capabilities required to support IT services in businesses. It helps organizations to gain competitive advantage by ensuring they are utilizing the best-practice approaches to IT available – helping IT services to meet the needs of the customers within the budget in an cost-effective way. There are different sources of the best practices: proprietary knowledge / internal experience, standards / industry practice and training and education / academic research.
ITIL is considered one of the standards containing the body of knowledge in best practice and is being adapted by organizations worldwide to establish and improve capabilities in service management.
  • It works – as ITIL embraces a practical approach with a common framework
  • Vendor-neutral – not tied to any technology, platform or industry, owned by the UK Government
  • Non-prescriptive – designed for all types of organizations, advocates “adopt and adapt”, doesn’t specify how the best practices are to be structured or carried out
  • Best practice – accumulated through experiences by service providers worldwide
ITIL enables organizations to deliver benefits, values and return on investment on a sustainable approach. It allows a cultural shift by the adoption of standard approach to service management across the entire organization.
ITIL standardizes the strategic approach to the management of services, the performing organizations just need to make minor adjustments to meet their business needs. This is the core of ITIL’s approach to service management.
