6.1. Key Concepts of Value Stream Mapping and Management
💡 First Principle: A value stream is the end-to-end set of steps that takes a specific demand all the way to delivered value — and naming value streams lets an organization see and improve flow, which is invisible when you only look at individual activities.
Why care: organizations that manage tasks but not flow optimize each step while the overall journey stays slow and wasteful — work piles up between hand-offs nobody owns. Value streams make the whole journey visible. The mental model: trace one unit of demand (a customer request) from start to finish and watch where it waits, loops, or stalls.
⚠️ Common Misconception: That a "core" value stream is more important than an "enabling" one. The distinction is about relationship to customer value, not rank — both are necessary.
