Information Technology (IT) : According to the United Kingdom Academy of Information Systems, IT is the “ means by which people & organizations, utilizing technology, gather, process, store, use, & disseminate information. ”
IT has evolved through 4 eras since 1960s: 1 st^ Era Mid 1960’s → Mid 1970’s Implementation of large mainframe computers & business software written in COBOL programming language. 2 nd^ Era Mid 1970’s → Mid 1980’s Transition from mainframes to minicomputers/personal computers Rise of personal computers for productivity applications 3 rd^ Era Mid 1980’s → Mid 1990’s Growth of the Internet Internetworking of computer systems within organizations 4 th^ Era Late 1990’s → Present , Internet Age Ubiquitous computing driven by the internet, search engines, social media, and personal computing devices. Investments are made into a variety of technologies enabling or enabled by CAMBRASIA
1. Evolution of Internet Technologies Since the 1990s The internet has evolved beyond managing only digital data. It now includes integration with the real world through various technologies. 2. Internet of Things (IoT) IoT is a key development that connects physical objects to the internet. Sensors are used in machines and devices to detect real-world states. These real-world data points are converted into digital representations. This enables mutual interaction: the internet affects real-world events, and vice versa. The internet today is not just digital, but also a hybrid of digital and physical systems through IoT. 3. Big Data Big Data arises because of the proliferation of computing devices and software applications. There is now a vast amount of data from both business and social domains. The data is often unstructured and heterogeneous (many formats). Special techniques and technologies are needed to handle and analyze this kind of data. "Big Data" is an umbrella term for: Data analysis techniques Supporting hardware and software Approaches to manage large volumes of unstructured data
Capabilities and Services provided by an IT organization are traditionally based on 4 traditional architectural domains.
The benefits of using ITSM in an organization:
ITSM frameworks and standards are a structured guide for organizations to
Framework of tools, resources, & guidance to govern and manage an organization’s IT Framework for the organization’s enterprise architecture (EA) practice. Framework of best practices that guides IT as a service- based organization. Focuses on security, risk management and information governance. EA seeks to align technologies so as to support business capabilities. 4 versions through its history.
The creation of the Information Technology Infrastructure Library ( ITIL ) was motivated by the rate of technological change in the 1980s and the inability of IT to keep pace with this change, leading to a lack of control within IT departments. The U.K. government’s Central Computer and Telecommunications Agency (CCTA), perhaps responding to the demand for improved IT services, developed a set of procedures for IT services and management in 1989. These procedures became known as ITIL.
The procedures were modeled on Dr. William Deming’s p lan- d o- c heck- a ct ( PCDA ) method, a systematic approach to problem-solving and solution implementation.
Added the Service Value System (SV S), intended to help IT identify opportunities for value creation.
Emphasized a lifecycle approach for service management and added still further new process. 5 core reference books : Service Strategy, Service Design, Service Transition, Service Operation, and Continual Service improvement.
Added processes for problem management, release management, incident management, and more. During this time, ITIL evolved into the most widely accepted ITSM framework , influencing various other standards (e.g. ISO 20000)
Recommended process for common IT services , such as help desk management, change management, and software distribution. Provided guidance for IT management functions , such as capacity management, contingencyplanning, and cost management.
can be defined as a collection of experiences that one or more service consumer types will have white using a service. For example, a service that provisions laptops is
6. Co-Create - Often seen as the most important step. - It is when the service is provided and consumed , with the intention of value co- creation for all stakeholders in the service. 7. Realize - Purpose: Ascertain that value has been achieved and understand how the service can be improved for the consumers and providers. - The activities in this step are to track, assess, evaluate the realization of value, and identify improvements for future inclusion.
Operating models are a means by which the business will have a plan for delivering value to the entities that purchase its products and services. The IT organization will also have an operating model for delivering value to the internal and external stakeholders of the business. That is, the IT operating model represents how IT functions and the activities in which IT engages. Category Business IT Processes The steps need to be taken to deliver value to a customer; Processes answer the question of how the work is done The workflows or value streams that enable IT to deliver the value propositions. Organization The structure of the people who participate in the processes The IT employees and their skills Locations Where the work takes place and the necessary assets Locations of assets, such as buildings, machinery, and intellectual property Information The data and software solution used to gather the data IT services, IT systems, including applications, data, infrastructure Suppliers External participants in the processes External parties supporting the work of the IT organization Management system Manages the processes, as well as the measurement of progress Manages the processes, as well as the measurement of progress
The activities of the operating model can be connected into value streams. Value is defined as the “perceived benefits, usefulness, and importance of something.” A value stream is the set of activities necessary to design and deliver a specific product or service. In their customer journey, value is co-created between stakeholders, providers, and consumers. Value can be subjective since stakeholders may have different opinions depending on their perspective.
Other business tools can be used to provide in-depth assessment for each dimension. PESTLE analysis is often recommended to be used together with the four dimensions: Political factors e.g., government policy, legislative changes, local and organizational leadership Economic factors e.g., supply and demand, interest rates, and talent availability Sociocultural factors e.g., culture and demographics Technology e.g., new and changing technologies Legal factors e.g., consumer laws, cybersecurity, and regulatory frameworks Environmental factors e.g., environment-related laws and green computing
The Service Value System (SVS) is ITIL’s high-level strategic approach , defining how the components of ITIL work together for ITSM Service Value System
Opportunities & demands are inputs to the Service Value System (SVS) → Opportunities – Possibilities to improve processes by adding value through services. → Demand – The need / desire for services / products that provide value. Both trigger activities withing the SVS, aiming to realize value through new or improved services.
Conducting regular reviews of the services and the level of value achieved by the organization and its parts.
ITIL V4 introduced the Service Value Chain (SVC) as the operating model for the actual delivery of services. It involves 6 possible activities :
1. Engage Connecting with stakeholders to understand their needs and identify opportunities for improvement. Involves “ all incoming and outgoing interactions with parties external to the value chain are performed via Engage” 2. Plan Establishing a “ shared understanding of the vision, current status, and improvement direction for all four dimensions and all products and services across the Organization” 3. Improve An ongoing effort to search for opportunities for improvements to the processes and other components of the value chain for all four dimensions. Occurs in alignment with the Plan activities. 4. Design & Transition Creating services to meet stakeholder needs and expectations, followed by the transition of the services so that the stakeholders can achieve value from the service. Receives inputs from the Engage, Plan, and Improve activities. 5. Obtain & Build Constructing components of the service or obtaining them from a supplier to meet the specified needs of the stakeholders. Receives inputs from the Design and Transition activity. 6. Deliver & Support Making available a service to consumers, after it has been built, and providing support for the service. The value chain activities are combined in a service value stream, responding to demands & opportunities to realize value from products & services while using the required ITIL practices, roles and activities. Value Chain Example :
The continual improvement model provides a structured approach for implementing changes to services to meet stakeholders’ evolving expectations as the organization changes. Using this model, services are regularly evaluated to
These principles are expected to be long-lasting. Benefits:
The purpose of services is to bring value to the organization, its customers, its stakeholders, and to the service providers The goal of this principle is to eliminate waste of time, resources, and efforts by focusing on the benefit to the organization in the manner that the organization perceives value. In other words, stakeholders need to recognize “services for what they are – a vehicle for value” At a high level, leadership should understand the organization’s perspective of value , understand why consumers use services, and encourage staff to focus on value overall. From an operational perspective, this principle should be applied by understanding service consumers and their perspectives of value, how they use the service, itemizing the costs to the consumer, identifying the risks of the services, and several other activities
It is common to believe that our request is unique , and our requirements are new , so that we need to innovate from scratch , but this can be inefficient and ignore valuable knowledge This ITIL principle intends to remind stakeholders that when a new service is created, modifying an existing service might be sufficient, and even be faster and less demanding of resources In other words, it is a reminder to be conscious of the investment of expertise, time, and resources already expended in the creation of existing services. If the existing service cannot be adapted, there may be resources such as outside providers, processes, technologies, and more that can be used directly or as guidance in creating a new service To apply the principle, stakeholders should identify similar services to understand the existing state , review their components (process, resources), and assess whether current services can be expanded But they should also identify risks associated with such an expansion and acknowledge that existing services may not be an acceptable starting point and that a new service may be needed.
Often, it is best not to attempt to solve every problem at once ( “boiling the ocean” , “big bang approach” ), as it may lead to over-worked team members, frustrated users, and rework. → Instead, by sectioning the tasks into smaller pieces , the tasks can be accomplished in a controlled manner. Iterative progression allows the team to identify and deliver small pieces of value and review them with the service consumers and other stakeholders. → In turn, service development efforts can be adjusted based on the continuous feedback. As stakeholders experience the services, changes to the requirements might be necessary to achieve the expected value. → It is also possible that changes might result in additional value that had not previously been understood. This principle integrates concepts from the Agile Manifesto into ITIL:
Like “start where you are,” this principle reminds not to complicate what needs to be done. Use what you have, if possible, and keep it simple. → This also means to not to deliver services that exceed what has been requested, which often overcomplicates the services and extends the delivery time. Like “focus on value,” this principle reminds stakeholders to be efficient in the development efforts. → Focus on the requirements and the anticipated value while keeping the work practical and straightforward. The Pareto principle , identified in 1896 by Vilfredo Pareto, says that “80% of consequences come from 20% of the causes, asserting an unequal relationship between inputs and outputs .” → Thus, in relation to IT services, the principle reminds that 20 percent of the effort will likely be invested to create services to meet 80 percent of the variations identified by stakeholders, and vice versa. It is recommended that stakeholders attempt to achieve their goals with “the least possible steps and effort.” Variations should be identified and ranked by the level of value creation and expected frequency of occurrence. → Rather than build the last 20 percent of variations into the services, it is better to generalize exception handling. Over time , modifications can be made to services to handle variations that occur more frequently. Furthermore, it should be ensured that every service activity needs to participate in generating value.

ITIL describes a practice as a “set of organizational resources designed for performing work or accomplishing an objective.” ITIL4 provides 34 practices in 3 groups Previously, ITIL3 included 26 processes in 5 areas. The new structure introduced in ITIL4 encourages stakeholders to consider many components in addition to the process workflow. The organizational resources that participate in the practices include the 4 service management dimensions:
ITIL4 includes 34 practices, which are categorized into 3 groups: Organizations & people Information & technology Partners & suppliers Value streams & processes General Management Practices
