The Four Dimensions · Topic 2 of 2
The Four Dimensions Explained
What each ITIL dimension covers: organizations and people, partners and suppliers, information and technology, and value streams and processes.
- 3 min
- Organizations and people: structure, roles, culture, leadership, skills.
- Partners and suppliers: contracts, sourcing, supplier integration.
- Information and technology: data, knowledge and tools.
What it is
Each of the four dimensions looks at a product or service from a different angle. The exam often describes an activity or an item and asks which dimension it belongs to, so you need a clear picture of what each one contains.
How it works
Organizations and people
Covers how the organization is arranged and the people in it: organizational structure (teams and reporting lines), roles and responsibilities, culture and values, leadership, competencies and skills, and staffing levels.
Example: defining the roles a new service team needs and who each reports to.
Partners and suppliers
Covers the organization's relationships with other organizations that help design, deliver and support products and services: contracts and agreements, sourcing decisions (build in-house or obtain from another organization), and how several suppliers' contributions work together as one service. Relationships range from formal contracts to flexible partnerships.
Organizations rely on suppliers for expertise or capacity they lack, but a supplier contract does not remove the provider's accountability for outcomes.
Information and technology
Covers the information and knowledge needed to manage products and services and the technologies that support them: data, knowledge articles recording known solutions, workflow and automation tools, dashboards and analytics, and newer technologies such as AI.
Example: a workflow management system that routes requests to the right team automatically.
Value streams and processes
Covers how work is organized to create value:
| Term | Meaning |
|---|---|
| Value stream | The series of steps an organization undertakes to create and deliver products and services to consumers |
| Process | A set of activities that turns inputs into outputs |
A value stream can draw on several processes along the way. Understanding value streams shows where each step sits, so activities that add no value can be found and removed.
If an option mentions roles, culture or skills, think organizations and people. Contracts and sourcing: partners and suppliers. Data, knowledge and tools: information and technology. Steps and workflows: value streams and processes.
How the exam asks about this
- "A skills matrix belongs to which dimension?" Organizations and people.
- "Deciding whether to build in-house or outsource is part of which dimension?" Partners and suppliers.
- "Knowledge articles recording known solutions belong to which dimension?" Information and technology.
What to remember for the exam
- Organizations and people: structure, roles, culture, leadership, skills.
- Partners and suppliers: contracts, sourcing, supplier integration.
- Information and technology: data, knowledge and tools.
- Value streams and processes: the steps that create value and the activities that turn inputs into outputs.
- A value stream is end to end; a process is a set of activities within it.
Do not treat a value stream and a process as the same thing. The value stream is the larger flow; processes are parts of it.
Common mistakes
Putting a contract under information and technology. Contracts belong to partners and suppliers.
Calling a tool a process. Tools are technology; processes are activities.
Forgetting culture. Culture is part of organizations and people.
