The 12 Agile Principles That Made Scrum Possible
The Agile Manifesto (2001) defines 12 principles that every Scrum framework is built on. Here they are in plain language.
The Principles
| # | Principle | What It Means |
|---|---|---|
| 1 | Customer satisfaction through early delivery | Ship value every Sprint |
| 2 | Welcome changing requirements | Backlog is never frozen |
| 3 | Deliver working software frequently | Increment every Sprint |
| 4 | Business people & devs work together daily | PO sits with the team |
| 5 | Build around motivated individuals. Trust them. | Self-managing, no micromanagement |
| 6 | Face-to-face is most efficient | 15-min standup beats 10 Slack threads |
| 7 | Working software is primary progress measure | Not Gantt charts. Does the Increment work? |
| 8 | Sustainable pace indefinitely | No death marches |
| 9 | Continuous technical excellence | DoD, refactoring, testing |
| 10 | Simplicity — maximize work not done | YAGNI. Build only what you need now. |
| 11 | Self-organizing teams = best architectures | Devs decide how. No PM assigns tasks. |
| 12 | Regular reflection, tune and adjust | The Sprint Retrospective |
The 4 That Matter Most
#12 — The Retrospective This is the Sprint Retrospective. “At regular intervals, the team reflects on how to become more effective, then tunes and adjusts.” If you memorize one principle, make it this one.
#2 — Embrace Change “Welcome changing requirements, even late in development.” The Product Backlog exists because of this principle. Change is fuel, not friction.
#4 — Daily Collaboration “Business people and developers must work together daily.” The Product Owner is part of the team, not a distant stakeholder.
#7 — Working Software as Progress “Working software is the primary measure of progress.” Not slide decks. Not documentation. A usable Increment every Sprint.
One-Liner
The 12 principles are the Manifesto’s how — Scrum is the framework that makes that how repeatable across every Sprint.
