PSM 1
Imagine you are a scrum master in a small organization that tries to adopt scrum. There are 10 developers and a product owner. How can they be divided into teams?
-2 teams of 6 and 4 people (after a short meeting the developers decided this is the best option) -3 teams of 4, 3, 3 people (each team is cross functional)
Who is responsible for product backlog refinement?
The product owner and the development team
Who estimates the work during the sprint and measures the sprint progress?
The development team
An organization has decided to adopt scrum, but management wants to change the terminology to fit with the terminology already used. What will likely happen if this is done?
All of the above -without a new vocabulary as a reminder of the change, very little change may actually happen -the organization may not understand what has changed with scrum and the benefits of scrum may be lost -management may feel less anxious
The scrum artifacts are:
Product backlog Sprint backlog Increment
Scrum artifacts
Represent work or value. Designed to maximize transparency of key information -Product backlog -> product goa -Sprint backlog -> sprint goal -Increment: definition of done
Who updates the remaining work during the sprint?
The Development Team
Who is responsible for all the estimates in the product backlog?
The development team
Who is responsible for tracking the total work remaining in the sprint backlog to project the likelihood of achieving the sprint goal?
The development team
What does it mean to say that an event has a timebox?
The event can take no more than a maximum amount of time

The people in the scrum team who are committed to creating any aspect of a usable increment each sprint. They create a plan for the sprint (the sprint backlog), instill quality by adhering to a DoD, adapt their plan each day toward the sprint goal, and hold each other accountable as professionals
Who should know the most about the progress toward a business objective or a release, and be able to explain the alternatives most clearly?
The product owner
Who is responsible for coping with incomplete artifact transparency?
The scrum master
