Q

An org has recently started practicing Scrum. The sprint planning meetings have been taking a long time because the Scrum team members and stakeholders do not have the knowledge about the content or priority of product backlog items being considered. Whose responsibility is it to prepare the sprint planning attendees to help with better discussions?

A

PO, they should ensure the attendees are prepared to discuss the most important product backlog items and how they map to the product goal.

Q

A finance company is developing a product/ software. Functions within the product are complex and some take longer than a sprint to develop. Regardless, they need to deliver an increment of releasable software every print. T or F?

A

False, the term potentially releasable is o longer used to describe the increment. The team should work on and deliver a product increment which is usable and valuable at the end of every sprint.

Q

A Scrum team is just formed, and they are about to begin work. There is no sprint 0 and the product backlog items haven’t even started. While the pO works on getting the product backlog started, what is enough to start a first sprint?

A

A first sprint requires no more than a PO, developers and enough ideas to potentially complete a full sprint. Scrum is founded on empiricism and learn thinking. Empiricism asserts that knowledge comes from experience and making decisions based on what is observed. Lean thinking reduces waste and focuses on the essentials. Both encourage staring work rather than having prolonged discussions about it.

24
Q

Which of the below the PO can delegate?

a. Developing and explicitly communicating the product goal
b. Creating and clearly expressing product backlog items
c. Ordering the items in the product backlog to best achieve goals and missions
d. Optimising the value of the work the developers perform/ value of the product
e. Ensuring that the product backlog is visible, transparent and clear to all

A

All but optimising the value of the product as it’s their responsibility.

25
Q

What is a definition of done?

A

It’s a formal description of the state of the increment when it meets the quality measures required for the product. The moment a backlog item meets it, an increment is born. It creates transparency by providing everyone a shared understanding of what work was completed as part of the increment. If an item doesn’t;t meet it, it goes back to backlog. All members should have a shared understanding of what it means for work to be complete to ensure transparency.

26
Q

What is a product increment?

A

An increment is the sum o fall the product backlog items completed during the sprint plus the value of the increments of all previous sprints. An increment is a concrete steppingstone toward the product goal. Each increment is additive to all prior increments and thoroughly verified, ensuring that all increments work together. in order to provide value, the increment must be usable. An increment may be delivered to stakeholders prior to the end of the sprint.

27
Q

New Scrum teams have been created to build in product. 2 devs are concerned that their work is not going to remain aligned with a dev in another team. What advise would you give?

A

It is the responsibility of the devs to work with other scrum teams members as needed to make sure that their sprint work is aligned to create an integrated increment.

28
Q

Non-functional requirements can be incorporated into the product by what?

A
  1. have them as part of DoD
  2. Having them as part of acceptance criteria
  3. Including them as product backlog item itself
29
Q

What happens during product backlog refinement?

A

It’s the act of breaking down and further defining product backlog items into smaller precise items.

30
Q

What is the most effective way to order the product backlog?

A

A PO decides the order of the product backlog based on the complexity, risk, dependency and size of each item.

31
Q

Jack is a developer in a Scrum team and is asked to prepare the sprint backlog. Jack can only add the functional items which are required to meet the sprint goal in the sprint backlog. T or F?

A

False. It’s a collection of work items planned for the sprint. Includes functional and non-functional work. If there are some ‘developer stories’ ie. removing technical debt, they can be introduced by the developers (if the PO agrees) to the backlog and from there into the sprint.

32
Q

All but 4

36
Q

Nexus is a framework which binds together the work done by approx. how many teams?

A

3-9

37
Q

What happens when the DoD changes? (in Nexus). select one best answer

  1. The changed DoD should be communicated to all the clients
  2. The Nexus integration team will discuss it during retro and let the individual scrum teams adapt to it. it may not be implemented straight away.
  3. Based on the new DoD, individual scrum teams include all the changes in the current sprint or next.
A

2.

38
Q

Reps from scrum team a and b are participating in sprint planning. and the teams have quite a few dependencies. Which techniques will help reduce these?

  1. Reassign the team members from scrum team a to b to decrease the cross-team dependencies
  2. order nexus sprint backlog appropriately so things are picked up in the right order
  3. Extend the length of sprint 1 to allow more time
  4. Merge the teams
A

1 and 2

39
Q

What is the role of the Nexus integration team?

A

They do not do integration work but guide teams to do it.
They do not coordinate the work betweenn scrum teams.
They raise transparency by coaching and guiding the scrum teams to acquire, implement and learn the Nexus practices and needed tools. They take ownership of integration issues. They may deliver tools and technology to hep make integration run more smoothly. They coach individual scrum teams on the necessary dev, infrastructure etc. standards to ensure the development of quality integrated increments.

40
Q

What does a blue vertical arrow mean on a cross-team refinement board?

A

Blue vertical arrow shows dependency across teams within a single sprint. One team will build an item in a sprint that is needed by an item that will be delivered the same sprint by a different team. High risk relationship

41
Q

What does a red downward facing arrow mean on a cross-team refinement board?

A

It is an external in-sprint dependency. A team is relying on another delivered by an external group in the same sprint to build a subsequent item. This is an extremely high risk item.

42
Q

How do you read the cross-team refinement board?

A

More arrows associated to a product backlog item indicate high risk due to the number of dependent items impacted. Thea team refinement board visualisation helps the teams within Nexus identify ‘critical path’ work and provides basis for convos about ways to minimise or remove this impact.

43
Q

What is the purpose of Nexus daily scrum?

A
  1. inspect the current state of the integrated increment against nexus sprint goal
  2. opportunity to identify integration issues and make them transparent
  3. identify newly discovered cross-team dependencies
  4. identify cross-team impacts.
44
Q

The nexus integration team consists of professionals who:

  1. are not allowed to work as developers in scrum teams
  2. coach the individual scrum teams on the necessary development, infrastructural or architectural standards required by the org to ensure the development of quality integrated increments
  3. ensure the scrum teams within the nexus understand and implement the practices and tools needed to detect dependencies and frequently integrate all artifcats
  4. are skilled in the use of tools, various practices and the general field of systems engineering
A

BCD

45
Q

When is the Nexus sprint planning considered complete?

A

When each Scrum team has finished their individual sprint planning events and sprint goal has been formulated.

46
Q

What is discussed at Nexus sprint retro?

A

Did Nexus generate technical debt?
Were all artefacts, particularly code, frequently and successfully integrated?
Was the software successfully built, tested and delayed often enough to prevent the overwhelming accumulation of unresolved dependencies?

47
Q

The objectives of the Nexus sprint review are?

A
