3.1.1. The Four Dimensions Named
💡 First Principle: Naming the four dimensions — organizations and people, information and technology, partners and suppliers, value streams and processes — gives you a complete-coverage checklist, where "complete" is the whole point.
The four dimensions of product and service management are: organizations and people (the structures, roles, culture, and skills of the people involved); information and technology (the information needed and the technologies used to manage it); partners and suppliers (the external organizations involved in creating and delivering services); and value streams and processes (how the various activities are organized to create value, and the specific procedures within them).
⚠️ Exam Trap: Memorize all four exactly — the exam tests recall of the complete set, and a "list" question may offer a plausible-sounding fifth (like "governance" or "customers") that is not one of the four dimensions.
Reflection Question: If you only ever attended to "information and technology," which kinds of failure would you systematically miss?
