Scrum in practice: Roles, sprint and the four meetings
In short: Scrum works in sprints of one to four weeks with three roles, three artifacts and four meetings so that a team regularly produces deliverable results and learns.
In more detail: Scrum is the best-known agile framework. It prescribes no techniques but a rhythm with transparency, inspection and adaptation (empiricism).
In Depth
Three roles
- Product owner (PO): responsible for the value, maintains and prioritises the product backlog, decides what is built.
- Scrum master: ensures the team understands and applies Scrum, removes impediments, facilitates; not project management.
- Development team (developers): self-organising, brings all skills, decides how to build; typically 3 to 9 people.
Three artifacts
- Product backlog: ordered list of all wishes (user stories).
- Sprint backlog: the items chosen for the sprint plus plan.
- Increment: the working result that meets the definition of done.
The sprint and the meetings
A sprint (1 to 4 weeks, fixed length) contains:
- Sprint planning: what do we build (sprint goal), how?
- Daily scrum (15 minutes daily): progress, plan for the day, impediments.
- Sprint review: show the result to the stakeholder, get feedback, adjust the backlog.
- Sprint retrospective: how do we work? What do we improve in the next sprint? In between refinement (backlog care, estimating).
Tips and pitfalls
- Sprint goal understandable and not changed mid-sprint.
- Velocity (points completed) helps planning but is not performance measurement.
- Set the definition of done together.
- Frequent pitfalls: Scrum-but (omitting rules), daily as a reporting round for the boss, PO not reachable, sprint overload, no honest retro.
- Alternatives/complements: Kanban (flow instead of sprints), XP, SAFe/LeSS for large organisations. In the IHK documentation you explain how you adapted Scrum (for example a one-person project: sprint planning and review with the trainer).
