PSM I is based on the Scrum Guide rather than fixed-weight domains. This is a plain-English summary of what to master; the Scrum Guide is authoritative.
Scrum theory and values
Empiricism (transparency, inspection, adaptation), lean thinking, and the five Scrum values (commitment, focus, openness, respect, courage).
The three accountabilities
- Scrum Master — fosters effectiveness, coaches the team, removes impediments.
- Product Owner — maximises value and owns the Product Backlog.
- Developers — create a usable Increment each Sprint.
The five events
The Sprint (the container for all work), Sprint Planning, the Daily Scrum, the Sprint Review, and the Sprint Retrospective.
The three artifacts and commitments
Product Backlog (Product Goal), Sprint Backlog (Sprint Goal), and Increment (Definition of Done).
The Scrum Master role in depth
Servant leadership, coaching, facilitation, and serving the Scrum Team, Product Owner and organisation — not acting as a traditional project manager.
