Core ITIL4 Definitions
Service, Value, Utility, Warranty & more
▼
- Service: A means of enabling value co-creation by facilitating outcomes that customers want to achieve, without managing specific costs and risks.
- Value: The perceived benefits, usefulness, and importance of something. Value is always co-created — both provider and consumer contribute.
- Utility: The functionality offered by a product or service to meet a particular need. Think: "Fit for purpose".
- Warranty: Assurance that a product or service will meet agreed requirements. Think: "Fit for use" (available, reliable, secure, etc.).
- Output: A tangible or intangible deliverable of an activity (e.g., a report, a deployed change).
- Outcome: A result for a stakeholder enabled by outputs. The end goal achieved (e.g., improved customer satisfaction).
- Cost: The amount of money spent on a specific activity or resource. Can be removed from consumer (benefit) or imposed (cost).
- Risk: A possible event that could cause harm, loss, or make it harder to achieve objectives. Can be removed from consumer or imposed.
- Organisation: A person or group of people that has its own functions, responsibilities, authorities, and relationships to achieve objectives.
💡 Exam Tip
Utility + Warranty = Value. A service must be both fit for purpose AND fit for use to deliver true value.The 7 Guiding Principles
Core recommendations for all situations
▼
- 1. Focus on Value: Everything should link, directly or indirectly, to value for customers and stakeholders.
- 2. Start Where You Are: Don't start from scratch. Assess what already exists and build on it.
- 3. Progress Iteratively with Feedback: Work in manageable sections and seek feedback at each stage.
- 4. Collaborate and Promote Visibility: Work together across boundaries and share information openly.
- 5. Think and Work Holistically: Consider the service as a whole — all four dimensions and all stakeholders.
- 6. Keep It Simple and Practical: Use the minimum number of steps. If a practice adds no value, eliminate it.
- 7. Optimise and Automate: Optimise first, then automate — not the other way around.
💡 Exam Tip
The guiding principles are universal — they apply to any initiative, situation, or organisation. Exam questions often describe a scenario and ask you to identify which principle applies.The 4 Dimensions
Every service must be seen from all four angles
▼
- 1. Organisations and People: Roles, responsibilities, culture, skills, and how people work together.
- 2. Information and Technology: Information managed by services, the technology and tools used (AI, cloud, security).
- 3. Partners and Suppliers: Relationships with other organisations involved in service delivery. Includes contracts and agreements.
- 4. Value Streams and Processes: The activities, workflows, controls, and procedures that achieve objectives.
💡 Exam Tip
The four dimensions are affected by external factors — PESTLE (Political, Economic, Social, Technological, Legal, Environmental). These are forces the organisation cannot control.The Service Value System (SVS)
The big picture of how value is created
▼
- Purpose: Describes how all components and activities work together to enable value creation.
- Input: Opportunity (possibilities to add value) and Demand (customer need/requirements).
- Output: Value — for the organisation, customers, and other stakeholders.
- 5 SVS Components: Guiding Principles · Governance · Service Value Chain · Practices · Continual Improvement
- Governance: The means by which an organisation is directed and controlled to achieve its objectives.
💡 Exam Tip
The SVS has exactly 5 components. Demand goes in → the 5 components work together → Value comes out.The Service Value Chain (SVC)
6 interconnected activities that create value
▼
- Plan: Ensure shared understanding of vision, current status, and direction.
- Improve: Ensure continual improvement of products, services, and practices.
- Engage: Understand stakeholder needs, ensure transparency and continual engagement.
- Design & Transition: Ensure products meet stakeholder expectations for quality, cost, and time.
- Obtain/Build: Ensure service components are available when needed and meet specifications.
- Deliver & Support: Ensure services are delivered according to agreed specifications.
💡 Exam Tip
The SVC activities are not linear — they interact flexibly to create value streams. All 6 activities connect to Practices and the Guiding Principles.Continual Improvement Model
7-step improvement cycle
▼
- Step 1: What is the vision? (business goals)
- Step 2: Where are we now? (baseline assessment)
- Step 3: Where do we want to be? (measurable targets)
- Step 4: How do we get there? (improvement plan)
- Step 5: Take action (execute the plan)
- Step 6: Did we get there? (measure and evaluate)
- Step 7: How do we keep the momentum going? (embed and repeat)
💡 Exam Tip
Continual Improvement is both a practice AND an SVS component. It applies everywhere — not just IT.Key Management Practices
Most commonly tested in the exam
▼
- Incident Management: Minimise negative impact by restoring normal service ASAP. Uses Priority = Impact × Urgency.
- Problem Management: Reduce likelihood and impact of incidents by finding root causes. 3 phases: Problem Identification → Problem Control → Error Control.
- Change Enablement: Maximise successful changes. Types: Standard (pre-authorised), Normal (CAB review), Emergency (urgent).
- Service Desk: Single point of contact between provider and users. Handles incidents and service requests.
- Service Request Management: Pre-defined, pre-agreed requests (e.g., password reset, new laptop). Low risk, no special approval.
- Service Level Management: Sets business-based targets in SLAs and ensures they are met.
- Monitoring and Event Management: Observe services and respond to events. Events: Informational, Warning, Exception.
- Knowledge Management: Uses DIKW model (Data → Information → Knowledge → Wisdom).
💡 Exam Tip
ITIL4 has 34 practices: General Management (14) + Service Management (17) + Technical Management (3) = 34.Service Relationships & Agreements
Providers, consumers, and how they interact
▼
- Customer: Defines requirements for a service and takes responsibility for outcomes.
- User: Uses the service day-to-day. May be different from the customer.
- Sponsor: Authorises budget and costs for the service.
- SLA (Service Level Agreement): Agreement between provider and customer defining service targets and metrics.
- OLA (Operational Level Agreement): Agreement between internal teams to support service delivery.
- UC (Underpinning Contract): Contract between a provider and an external third-party supplier.
💡 Exam Tip
Customer, User, and Sponsor can be the same person or different people. Example: a manager (Customer + Sponsor) buys software that their staff (Users) use daily.🃏 Flashcards
