ITIL 4 Foundation: The Prerequisite Baseline
Foundation is the prerequisite baseline for MEM. The exam assumes you already use ITIL 4 vocabulary - the service value system, the four dimensions, the service value chain, the guiding principles and the management practices - as working language rather than as recited definitions.
The core model
- The service value system joins five elements: guiding principles, governance, the service value chain, practices and continual improvement.
- Four dimensions: organizations and people; information and technology; partners and suppliers; value streams and processes. External factors (political, economic, social, technological, legal, environmental) act on all four.
- Value chain activities: plan, improve, engage, design and transition, obtain/build, deliver and support. They are building blocks, not a fixed sequence; value streams combine them.
- Value = utility (fit for purpose) plus warranty (fit for use), co-created with the consumer. Outputs are produced by the provider; outcomes are realized by the consumer, who carries cost and risk.
Guiding principles
Focus on value; start where you are; progress iteratively with feedback; collaborate and promote visibility; think and work holistically; keep it simple and practical; optimize and automate. They apply at every level of work, not only to projects.
Worked example
A service desk requests a new tool. Start where you are: examine the current configuration, reports and ticket data first, because part of the perceived gap may be knowledge and training. Progress iteratively with feedback: pilot with one team, measure, then scale. Reasoning: the principles remove risk and waste before capital is committed.
Traps
Reporting an output ("a server was deployed") as an outcome ("month-end close finishes a day earlier"). Reducing warranty to availability while ignoring capacity, continuity and security. Reading the value chain as a strict left-to-right flow.
