After the above 10 minutes video introduction from @hamids, lets find the roots of Scrum first. The first Scrum team was created directly from a paper which is required reading for any Scrum practitioner. Read Roots of Scrum: Takeuchi and Self-Organizing Teams for more details.
- Small working teams ( @richardbanks suggest 7+-2 team members).
- Embrace changing requirements.
- Deliver finish product frequently in Small batches – Continuous Deployment.
- Enable releasing product whenever required – Continuous Delivery.
Characteristics of Scrum
- Activity are time boxed.
- All project metrics, reports, and details are prominently displayed. Project status is displayed on a white board with post-it.
- Multi-disciplinary and self-organizing team. Team make the decisions themself.
- No specific engineering practices prescribed.
- Rather then counting man hours scrum team do product progression in a series of sprints(Time box iteration).
- Requirements are captured as items in a product backlog. (Master list of all work the team will do).
- Continuously tested as the software is created.(This help in continuous delivery)
Now, lets watch what @kschwaber has to say about Scrum.
In Scrum you have following Scrum ceremonies (meetings). Following are some points on what you do in each of the following ceremonies.
- Sprint planning meeting.
- Create sprint goals (high level objectives).
- Product owner, scrum master, team members (developers) attend these meetings.
- Ideally starts on Monday after the last sprint.
- Team members select items from the product backlog.
- Discuss the fine details of implementation.
- The daily scrum(daily stand up 15min).
- Team members answer the following questions,
- What did you do yesterday?
- What will you do today?
- What are the impediments in your way?
- The sprint review.
- Show new features or demonstrate the software.
- Do not spend more than 2 hours of preparation. Don’t show slides, just show code.
- Invite everybody who is interested.
- Ask for feedback.
- The sprint retrospective.
- This is the Kaizen part (continuous improvement).
- Discuss what is and what isn’t working.
- Typically spend 15-30 minutes.
- This meeting is done after every sprint review.
- Whole team participates, possibly customers and others.
- Ask following questions for next sprint,
- What will we start doing?
- What will we stop doing?
- What will we continue doing?
