I've used the following document "Fourteen Observations
of Good Scrum Practice" with success hope you will do also:
In summary A scrum team typically consists of around seven people who work together in short time boxed activity called sprints, with plenty of time for review and reflection built in. The mantras of scrum is “inspect and adapt,” and scrum teams are characterized by an intense focus on continuous improvement—of their process, but also of the product.
The main roles in scrum are
Product Owner: Own and drive the product and maximize the return on investment,
The Scrum master: act as a coach and guide the team to a higher of efficiency, self-organization.
The development Team :a highly collaborative and self-organized team doing the actual work.
Observation-1: Sprint is owned by the development team and SM should make sure to protect the team during the sprint from management interference that can negatively impact the sprint.
Observation-2: a common definition of done which is a result of negotiation between all the actors in Scrum team members, but the development has the final say.
Observation-3:The product backlog is owned and ranked by the Product Owner. Other team member can suggest features to add but is the PO who has the final say.
Oberservation-4:The Team is responsible for their own commitments and should only make commitments they truly feel they are going to fulfill.
Observation-5:The PO can set the priorities for the Team.
Observation-6: The Scrum Master has no authority over the activity of the team.The SM is the one who has the expert knowledge on the scrum framework.
Observation-7:Sprint planning is about what PBI the team will build and how they team is going to build it.
Observation-8:Sprint backlog, owned and maintained by the development team.
Observation-9: The daily scrum meeting is a timeboxed meeting to a max 15 minutes where the development team take the opportunity to sync their activities and answer the three question: What did you do ysetrday, what will you do today and any road blocks that other team members can resolve. The SM will facilitate the meeting.
Observation-10: the sprint review, it is the time for team to shine and present the sprint increment to the PO. Only demoble increment maybe demonstrated.
Observation-11: The retrospective is the time for the team to reflect on how they can improve.
Observation-12: stakeholders have no direct authority on the team and the SM should shield the team if the interaction with stakeholders is deemed a distraction
Observation-13: if the PO decide to terminate a sprint, they should organize a termination meeting with team to tell the team what is behind the cancellation and the team should come up with key leanings items to be communicated to the stakeholders
