Scrum Certification
Imagine you are a Scrum Master in a small Organization that tries to adopt Scrum. There are 10 developers and the Product Owner. How can they be divided into teams?
- 3 teams of 4, 3 and 3 people (each team is cross functional) - 2 teams of 6 and 4 people (after a short meeting the developers decided this is the best option)
What are the two primary ways a Scrum Master keeps a Development Team working at its highest level of productivity?
- By facilitating Development Team decisions - By Removing impediments that hinder the Development Team
How does the Scrum Master serve the Development Team?
- Coaching the Development Team in self-organization and cross-functionality - Helping the Development Team to create high-value products - Removing impediments to the Development Team's progress - Facilitating Scrum events as requested or needed - Coaching the Development Team in organizational environments in which Scrum is not yet fully adopted and understood
What are the five Scrum values?
- Commitment - Courage - Focus - Openness - Respect
What are the three main qualities the team model in Scrum is designed to optimize?
- Creativity - Productivity - Flexibility
Which two things does the Development Team do during the first Sprint?
- Deliver an increment of potentially releasable software - Develop and deliver at least one piece of functionality
How does Definition of "Done" help the Scrum Team?
- DoD is used to assess when work is complete on the product Increment - DoD guides the Development Team in knowing how many Product Backlog items it can select during a Sprint Planning - DoD ensures artifact transparency
The Scrum Master does the following regarding the Daily Scrum
- Ensures the Development Team has the meeting, but the Development Team is responsible for conducting the Daily Scrum - Teaches the Development Team to keep the Daily Scrum within the 15-minute time box - If others are present at the Daily Scrum, ensures that they do not disrupt the meeting
How does the Scrum Master help the Product Owner?
- Ensuring that goals, scope, and product domain are understood by everyone on the Scrum Team as well as possible - Finding techniques for effective Product Backlog management - Helping the Scrum Team understand the need for clear and concise Product Backlog items - Understanding product planning in an empirical environment - Ensuring the Product Owner knows how to arrange the Product Backlog to maximize value - Understanding and practicing agility - Facilitating Scrum events as requested or needed
What are the questions the Sprint Planning answers?
- How will the work needed to deliver the increment be achieved? - What can be delivered in the increment resulting from the upcoming Sprint?
What are Product Backlog features?
- It is dynamic - It is never complete - As long as a product exists, its Product backlog also exists
What are two essential features a Scrum Team should possess?
- It should have all competencies needed to accomplish the work without depending on others not part of the team - It should choose how best to accomplish their work, rather than being directed by others outside the team
Where can Scrum be used?
- Research and identify viable markets, technologies, and product capabilities - Develop products and enhancements - Release products and enhancements, as frequently as many times per day - Develop and sustain Cloud (online, secure, on-demand) and other operational environments for product use - Sustain and renew products.
What comprises Scrum?
- Roles - Events - Artifacts - Rules
Which events are time-boxed according to the Scrum Guide?
- The Sprint: 1 month or less - Sprint Planning: max 8 hours for 1 month Sprint - Daily Scrum: 15 minutes - Sprint Review: max 4 hours for one month Sprint - Sprint Retrospective: max 3 hours for one month Sprint
What is the input to the Sprint Planning?
- The latest product increment - Projected capacity of the Development team - The Product Backlog - Past performance of the Development team
How does the Scrum Master serve the Organization?
- They lead and coach the organization in its Scrum adoption - They plan Scrum implementations within the organization - They help employees and stakeholders understand and enact Scrum and empirical product development - They cause change that increases the productivity of the Scrum Team - They work with other Scrum Masters to increase the effectiveness of the application of Scrum in the organization
The length of a Sprint should be:
A) Short enough to keep the business risk acceptable to the Product Owner. B) Short enough to be able to synchronize the development work with other business events. Incorrect answer C) No more than one month. Missed correct answer D) All of these answers are correct. Answer: D
If an inspector determines that one or more aspects of a process deviate outside acceptable limits, when must an adjustment be made?
As soon as possible to minimize further deviation
True or False: All the Scrum teams working on the same product should have the same Sprint length
False - Scrum does not require having aligned Sprints for multiple teams
True or False: The structure of the Daily Scrum is well defined and constant. Every team member should answer the three main questions: What did I do yesterday? What will I do today? Do I see any impediment?
False - There is no any prescribed structure. The structure of the Daily Scrum is set by the Development Team and can be conducted in different ways if it focuses on progress toward the Sprint Goal. Some Development Teams will use questions, some will be more discussion based. It is still perfectly fine to use the questions, but other ways of conducting the meeting are also possible.
True or False: All the Scrum Teams working on the same product should have the same Sprint length
False. Scrum does not require having aligned Sprints for multiple teams
True or False: it is mandatory that the product increment be released to production at the end of each Sprint
False: product increment should be usable and releasable at the end of every Sprint, but it does not have to be released
True or False: The Scrum Team should choose at least one high priority process improvement, identified during the Sprint Retrospective, and place it in the Product backlog
False: to ensure continuous improvement, the Sprint backlog rather than the Product backlog includes at least one high priority process improvement identified in the previous Sprint Retrospective meeting.
What does Cone of Uncertainty show?
How much is known about the Product over time
How long should the Sprint planning be?
Maximum of 8 hours for a one month Sprint
When does a Development Team member become the sole owner of a Sprint backlog?
Never. All Sprint Backlog Items are "owned" by the entire Development Team, even though each one may be implemented by an individual development team member
What part of the capacity of the Development Team does Product Backlog refinement usually consume?
Not more than 10% capacity of the Development Team
What are the three main qualities the team model in Scrum is designed to optimize?
Optimize flexibility, creativity, and productivity
What are the Scrum Artifacts?
Product Backlog, Sprint Backlog, Increment
Which of the following services are appropriate for a Scrum Master in regard to the Daily Scrum?
Teach the Development Team to keep the Daily Scrum within the 15 minute time-box
Who is allowed to change the Sprint Backlog during the Sprint?
The Development Team
Who is allowed to participate in the Daily Scrum?
The Development Team
Who is responsible for creation of the Definition of "Done"?
The Development Team
Who is responsible for tracking the total work remaining in the Sprint Backlog to project the likelihood o achieving the Sprint Goal?
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 is the Increment?
The Increment is the sum of all the Product Backlog items completed during a Sprint and the value of the increments of all previous Sprints.
What is the Sprint Backlog?
The Product Backlog items selected for the Sprint, plus a plan for delivering the product increment and realizing the Sprint goal
Who is allowed to make changes in the Product Backlog?
The Product Owner but some work can be delegated to the Development Team
Who is responsible for monitoring progress toward high-level goals?
The Product Owner tracks total work remaining at least every Sprint Review.
Who is responsible for crafting the Sprint Goal at the Sprint Planning?
The Scrum Team crafts a Sprint Goal
What provides guidance to the Development Team on why it is building the Increment?
The Sprint Backlog
Imagine the following situation. At the Sprint Retrospective meeting the Scrum Team identified some improvements that can be done. What should the Scrum Team do?
The Sprint Backlog makes visible all the work that the Development Team identifies as necessary to meet the Sprint Goal. To ensure continuous improvement, it includes at least one high priority process improvement identified in the previous Retrospective meeting.
Which two meetings are people outside the Scrum Team allowed to participate?
The Sprint Review and Sprint Planning
Who creates the definition of "Done"?
The development organization (or Development Team if none is available from the development organization)
What is the result of the Sprint Review?
The result of the Sprint Review is a revised Product Backlog that defines the probable Product Backlog items for the next Sprint. The Product Backlog may also be adjusted overall to meet new opportunities.
The Product Backlog is ordered by
Whatever is deemed most appropriate by the Product Owner.
When might a Sprint be abnormally terminated?
When the Sprint Goal becomes obsolete.
When is a Sprint over?
When the time-box expires.
Could the Product Owner and the Scrum Master be a part of the Development Team?
Yes - Scrum does not prohibit the Product Owner or the Scrum Master do development work. However, it is not best practice because it could create a conflict of interest
