Memory hook: Owner orders value; Developers plan delivery; Master enables effectiveness.
Must remember
The Scrum Team contains a Product Owner, Scrum Master and Developers. It is cross-functional and self-managing, typically ten or fewer people. Cross-functional means the team collectively has/acquires the skills to create value; every individual need not be an expert in every discipline.
The Product Owner is accountable for product value and effective Product Backlog management. Work can be delegated, but accountability remains. One person holds this accountability; a stakeholder committee does not replace it. Developers decide how to do the work, maintain the Sprint plan and uphold quality. They are not limited to people with a programmer job title.
The Scrum Master helps establish Scrum and improve team effectiveness through teaching, coaching, facilitation and removing organizational impediments. This is leadership, not automatically line management or task allocation. Stakeholder pressure does not authorize the Scrum Master to dictate estimates or override the Product Owner’s ordering.
Self-management works within organizational goals and standards. Help the team solve its own problem when possible; act on barriers outside its reach. A team needing help is not evidence that a manager should permanently take over every decision.
Choose under exam pressure
| Requirement | Choice and reason |
|---|---|
| Who orders product work? | Product Owner, with input and retained accountability. |
| Who decides implementation? | Developers doing the work. |
| Organization blocks collaboration | Scrum Master helps remove the systemic barrier. |
Traps
- Delegating backlog work does not delegate Product Owner accountability.
- Self-management is not isolation from stakeholders or standards.
