Certified - ITIL Foundation v4

The glossary continues with terms beginning from H through P, providing the next layer of vocabulary essential for ITIL Foundation. These terms cover a wide range, from high-level perspectives like holistic thinking, to specific operational terms such as incident, problem, and known error. Learning them systematically ensures that when you encounter exam questions or workplace discussions, you have a precise and reliable understanding. Glossary study is not simply memorization; it is about grounding abstract words in meaning and context so that they become usable tools. By exploring H through P in this episode, we expand your fluency in the language of ITIL and reinforce the precision needed for both exam performance and professional communication.
A holistic perspective means integrating across all dimensions of service management rather than focusing narrowly on one. ITIL emphasizes that services succeed only when organizations and people, information and technology, partners and suppliers, and value streams and processes are considered together. For example, rolling out a new HR system requires not only software but also trained staff, supportive suppliers, and clear workflows. A holistic view ensures that these factors are coordinated. Without it, improvements in one area may be undermined by neglect in another. In both study and practice, holistic perspective is a reminder that service management is a system of interconnected parts, not isolated activities.
Hybrid delivery refers to the combination of predictive and adaptive methods. Predictive approaches, such as waterfall project management, emphasize upfront planning and linear execution. Adaptive methods, like Agile, emphasize iteration and responsiveness. A hybrid model blends the two, using structure where stability is essential and adaptability where change is frequent. For example, an organization might plan infrastructure upgrades with predictive scheduling while delivering application features iteratively using Agile. ITIL 4 recognizes hybrid delivery as a practical reality in modern organizations, where no single method fits all needs. This adaptability demonstrates ITIL’s flexibility and its compatibility with diverse working styles.
An incident is defined as an unplanned interruption to a service, or a reduction in its quality. This definition is precise and should be remembered word for word for the exam. For example, if a user cannot access email, that is an incident; if email is accessible but messages are delayed, that is also an incident. The focus is on the disruption of normal service, whether partial or complete. Incident management practices aim to restore service quickly, minimizing impact. Understanding “incident” in ITIL’s terms helps distinguish it from related concepts like “problem” or “event.” This clarity prevents confusion and supports accurate responses in both study and workplace contexts.
Information in ITIL is processed data that supports decisions and operations. Data on its own is raw and unorganized; when structured and contextualized, it becomes information that people can act upon. For example, a server log of temperature readings is data, but a trend report showing overheating patterns is information. Information management ensures that data is collected, processed, and presented in ways that support effective service management. ITIL emphasizes information as one of the four dimensions, highlighting its role as both an asset and a resource. Understanding the distinction between data and information reinforces ITIL’s focus on clarity, accuracy, and decision support.
Information security management is the practice of protecting confidentiality, integrity, and availability—often referred to as the CIA triad—of information and services. Confidentiality means only authorized people can access data, integrity means information is accurate and unaltered, and availability means it can be accessed when needed. Together, these qualities safeguard trust in services. For example, an online banking service must ensure that accounts are secure from unauthorized access, that balances are correct, and that services are available during critical hours. ITIL identifies information security as one of its essential practices, reflecting its centrality in modern organizations.
An input is any resource, trigger, or element that enters a value stream and enables an activity. Inputs can be raw data, requests from stakeholders, or materials needed to produce outputs. For example, in an incident management process, an input might be a user’s report of a service failure. Understanding inputs clarifies how value streams begin and how resources are transformed into outcomes. Without identifying inputs clearly, it becomes difficult to measure efficiency or effectiveness. In ITIL, inputs are the starting points that fuel processes, and recognizing them helps clarify the chain of activities that follow.
Integrity is the assurance that information is accurate, consistent, and complete. In ITIL’s context, integrity is part of information security, ensuring that data has not been altered without authorization and remains trustworthy for decision-making. For example, if medical records are tampered with, even subtly, the loss of integrity undermines patient safety. Maintaining integrity requires both technical measures, such as checksums and validation, and organizational practices, such as access control and audit logs. In the exam, integrity is most often seen in connection with confidentiality and availability, reinforcing its role as one of the three pillars of security.
A knowledge article is a documented piece of guidance intended for reuse and efficiency. These articles are often stored in a knowledge base and used by service desks or support staff to resolve incidents quickly. For example, a knowledge article might describe how to reset a password or troubleshoot a common error. The purpose is to capture knowledge once and make it reusable many times, reducing duplication of effort. Knowledge articles also support self-service, allowing users to solve problems independently. In ITIL, they reflect the principle of promoting visibility and collaboration by making knowledge accessible and actionable.
A known error is a problem with a documented root cause and a recorded status. Unlike a problem under investigation, a known error has been analyzed and understood, even if a permanent solution is not yet available. Workarounds are often associated with known errors, allowing services to continue despite unresolved underlying issues. For example, if a recurring printer error is traced to a driver incompatibility, the problem becomes a known error, and the workaround may involve restarting a service until a patch is deployed. In ITIL, distinguishing known errors from problems emphasizes progress in analysis and supports better decision-making.
Lean thinking is a philosophy that focuses on maximizing value while eliminating waste. Originating in manufacturing, it has been widely adopted in IT and service management. Waste in this context refers to activities that consume resources without adding value—such as unnecessary steps, delays, or redundant work. For example, reducing duplicate data entry saves both time and effort while increasing accuracy. Lean principles align with ITIL’s emphasis on efficiency and continual improvement, encouraging organizations to strip away unnecessary complexity. Understanding lean thinking helps reinforce why ITIL stresses simplicity and practicality in its guiding principles.
A major incident is an incident of highest impact, requiring special procedures and often dedicated resources. Major incidents disrupt critical business functions or affect a large number of users. For example, a complete outage of a company’s e-commerce site during peak shopping hours qualifies as a major incident. Because of their potential consequences, major incidents are handled differently from routine incidents, often involving rapid escalation, specialized communication channels, and leadership involvement. Recognizing major incidents ensures they are prioritized and managed appropriately, minimizing damage and restoring services swiftly.
Measurement and metrics are quantitative indicators of performance. A measurement is the act of obtaining data, such as recording the number of incidents resolved in a day. A metric is a derived indicator, often combining measurements into a meaningful form—for example, average resolution time. Metrics provide insight into whether objectives are being met and where improvements are needed. ITIL emphasizes that metrics should be aligned with value and outcomes, not just outputs. This distinction prevents organizations from chasing numbers that do not reflect true performance. For exam purposes, remembering that metrics derive from measurements helps clarify the relationship.
Monitoring is the systematic observation of services and components to detect events and patterns. Monitoring can be technical, such as checking server performance, or procedural, such as tracking incident trends. Its purpose is early detection and informed response. For instance, monitoring may reveal that login failures are spiking, signaling a potential outage or security issue. Monitoring feeds directly into event management, providing the raw observations that support decisions. In ITIL, monitoring is essential for visibility and for maintaining stability. Without it, services operate in the dark, increasing the risk of undetected failures.
A normal change is a change that must follow formal assessment and authorization procedures. Unlike standard changes, which are pre-approved and routine, normal changes require evaluation of risk and impact. For example, upgrading a database system would be treated as a normal change, requiring documentation, testing, and approval before implementation. Understanding normal changes is important because the exam may ask you to distinguish them from standard or emergency changes. Their defining feature is the need for structured authorization, ensuring that risk is assessed and managed responsibly.
An outcome is the result for a stakeholder enabled by a service. Outcomes differ from outputs: the output may be the deliverable, but the outcome is the effect it creates. For example, a reporting tool output might be monthly reports, but the outcome is better business decisions made from those reports. Outcomes capture the “so what” of services—why they matter in the first place. ITIL emphasizes outcomes because value depends on them. Customers judge services not by what they deliver but by how they improve lives or business results. This distinction between output and outcome is central to ITIL’s focus on value.

An output is any tangible or intangible deliverable produced by an activity. This is different from an outcome, which is the effect of that deliverable on stakeholders. For example, in a payroll service, the output is the pay slip generated for employees, while the outcome is the assurance that staff are compensated correctly and on time. Outputs can exist without delivering meaningful value, but outcomes cannot. This distinction is one of the most tested in ITIL, because many learners instinctively confuse the two. Remember: outputs are “what is produced,” outcomes are “what it achieves.” Recognizing this difference keeps your answers precise and aligned with ITIL’s definitions.
An opportunity is a favorable condition that can be exploited to add value or improve a service. Opportunities are the positive side of change, complementing risks, which are potential negative impacts. For example, adopting a new collaboration tool may create the opportunity for more efficient teamwork. In ITIL, opportunities are important because they reinforce the idea that change is not always a problem to be solved but can also be a chance to increase value. Continual improvement practices often focus on identifying opportunities, whether small adjustments or large innovations, and integrating them into the service value system.
A problem is defined as the cause, or potential cause, of one or more incidents. Unlike incidents, which are disruptions experienced directly by users, problems focus on underlying issues. For example, repeated printer outages are incidents, while the faulty driver causing them is the problem. Problem management aims to identify and address these root causes, preventing recurrence. Sometimes problems are resolved permanently, and sometimes they are documented as known errors with workarounds. In ITIL, distinguishing incident from problem is crucial: incidents are about immediate impact, problems are about long-term resolution. This distinction will appear repeatedly in exam items.
A process is a set of activities that transform inputs into outputs. Processes are structured and repeatable, ensuring consistent results. For example, the process of handling an incident may involve logging the issue, categorizing it, escalating if necessary, and resolving it. Processes provide stability, but in ITIL 4, they are framed as part of broader practices that also include people, tools, and resources. Understanding process as transformation of inputs to outputs highlights its role in ensuring efficiency and predictability. ITIL acknowledges processes but places them within the larger context of practices to emphasize adaptability and holistic resource use.
A practice, in ITIL, is broader than a process. It refers to a set of organizational resources designed for performing work. This includes people, tools, skills, and processes combined. For example, incident management as a practice encompasses not only the process of logging and resolving incidents but also the staff, training, systems, and policies that support it. Practices are designed to be modular and adaptable, fitting different contexts. This reframing in ITIL 4 replaces rigid process models with more flexible practices, ensuring relevance across organizations of all sizes. On the exam, be careful to distinguish practices from processes, as this reflects one of ITIL 4’s central shifts.
Priority is the relative importance assigned to incidents, problems, or changes, guiding the order in which they are addressed. Priority typically combines impact and urgency. For example, a minor error affecting one user may be low priority, while a major outage affecting thousands is high priority. The purpose of priority is to allocate resources intelligently, ensuring that the most critical issues are handled first. Without prioritization, teams may waste effort on less important tasks while vital issues languish. In ITIL, priority is not absolute; it is contextual, based on business objectives and customer needs.
A product is defined as a configuration of an organization’s resources designed to offer value to consumers. Products are not just physical items; they can be digital or service-based as well. For example, an online banking app is a product, consisting of technology, staff expertise, processes, and infrastructure combined. Products exist to enable services, which in turn produce outcomes for customers. This definition emphasizes that products are more than deliverables—they are bundles of resources intentionally structured to create value. Understanding product as part of ITIL’s vocabulary helps distinguish it from outputs, outcomes, and services.
A provider is any organization or unit that supplies services to consumers. Providers can be internal—such as an IT department delivering HR systems to employees—or external, such as a software company providing cloud services to customers. The key aspect of being a provider is the responsibility to manage services in a way that creates value for consumers. ITIL emphasizes that providers and consumers are engaged in value co-creation, not one-sided delivery. Recognizing the provider role helps clarify service relationships and ensures accountability. On the exam, recall that “provider” refers to the organizational role, not just the technical function.
Proactive monitoring is the practice of detecting issues before they impact customers. Unlike reactive monitoring, which responds after a disruption occurs, proactive monitoring identifies warning signs and trends early. For example, monitoring disk space allows teams to prevent outages before a server fails. This approach improves reliability, reduces downtime, and enhances customer experience. In ITIL, proactive monitoring is part of event management and continual improvement, reflecting the framework’s emphasis on anticipating needs rather than simply reacting. Understanding proactive monitoring helps illustrate ITIL’s value orientation—prevention is better than cure.
A post-incident review is a structured analysis conducted after a major incident, aimed at learning and preventing recurrence. This review documents what happened, why it happened, how it was resolved, and what can be improved. For example, after a significant outage, a post-incident review might reveal that monitoring thresholds were set too high, delaying alerts. The review then recommends corrective action, such as adjusting thresholds or improving communication protocols. In ITIL, post-incident reviews are part of the culture of continual improvement, transforming disruptions into opportunities for learning and growth.
Performance refers to how well a service or component achieves its expected targets. Performance is measured against indicators such as response time, throughput, or uptime. For example, a web application with a two-second response target demonstrates good performance if it consistently meets or exceeds that goal. Performance is not only technical but also experiential, reflecting how users perceive the service. In ITIL, performance measurement ensures that services remain aligned with agreed expectations and outcomes. It is also critical for continual improvement, as measuring current performance provides the baseline for progress.
The plan activity is one of the components of the ITIL service value chain. It ensures that there is a shared understanding of the vision, status, and improvement direction for all products and services. Planning includes setting objectives, aligning strategies, and preparing for upcoming changes. For example, before launching a new product, the plan activity ensures that resources are aligned, goals are defined, and dependencies are understood. Recognizing plan as a value chain activity highlights ITIL’s emphasis on purposeful direction rather than ad hoc activity. On the exam, remember that plan is about vision and preparation within the service value system.
A policy is a formally documented statement of management expectations and rules. Policies establish boundaries, ensuring that practices are carried out consistently and in alignment with organizational objectives. For example, a security policy may require multi-factor authentication for all administrative accounts. Policies provide guidance without prescribing every detail, striking a balance between flexibility and control. In ITIL, policies are essential for governance, ensuring that practices reflect organizational strategy and compliance requirements. Understanding policy as a defined management expectation reinforces the connection between governance and daily operations.
A portfolio is the collection of services and products managed to achieve value for the organization. Just as a financial portfolio manages different investments, a service portfolio balances offerings to meet strategic goals. For example, a company may maintain a portfolio that includes customer-facing applications, internal HR systems, and infrastructure services. Managing this portfolio involves decisions about investment, prioritization, and retirement of services. ITIL emphasizes the portfolio as a tool for aligning resources with organizational value, ensuring that every service contributes to overall strategy.
Finally, a problem record is the documented details, history, and status of a problem. It captures analysis, known errors, workarounds, and resolution plans. For example, if recurring outages are traced to network instability, a problem record would document the investigation and proposed fixes. Problem records ensure visibility and continuity, so that analysis is not lost and teams can build on past work. In ITIL, they represent the discipline of structured problem management, turning reactive firefighting into systematic improvement. For exam purposes, remember that a problem record is not the same as an incident log—it is specifically tied to problem analysis and resolution.
