Zooming In: Parts

LevelDefinition
NeedsThe purpose of the system: what it is there to satisfy in its wider environment.

From the perspective of {X}, this part of the system exists in order that {Y} can be achieved.
ValuesWhat the system and people care about or are optimizing for, which then guides which principles they choose.

We optimise the system for {X}, so that meeting the Needs is more likely.
PrinciplesHow we choose to act. Usually toward optimizing values.

We leverage {X} to get more of what we Value.
PracticesConcrete, observable ways of working that implement principles day to day—things like stand‑ups, retrospectives, checklists, and team boards.

We do {X} to apply the Principles that matter in this context.
ToolsSpecific software or artifacts (like Jira, checklists, digital vs physical boards) that you use to implement chosen practices.

We use {X} to apply our Practices more efficiently.
