A
  • Sprints and Releases roll up to milestones

Q

When is Release Planning Done in Scrum?

A

At the beginning in the product planning stage (AKA Sprint Zero)

Refinements are also done every sprint as part of sprint review or in planning for the next sprint.

Q

Scrum Artifacts

A
  • Represent work or value
  • Maximize transparency of key information
    • Product Backlog
    • Sprint Backlog
    • Product Increment
21
Q

Scrum Events

A

Opportunity to inspect and adapt scrum artifacts

  • Sprint
  • Sprint Planning
  • Daily Scrum
  • Sprint Review
  • Sprint Retrospective
22
Q

Spike

A
  • Technical Investigation Story
  • Created to research a question or resolve a problem.
  • Focused on finding answers
  • Not directly part of a shippable increment
23
Q

Sprint Backlog

A
  • An overview of the development work to realize a sprint goal.
  • A forecast of functionality and the work needed to deliver it
24
Q

Sprint Goal

A
  • An expression of the purpose of a sprint
  • Why (goal)
  • What (Selected PBIs)
  • How (Plan for delivering the increment)
25
Q

Sprint Planning Process

A
  • <= 8 hour timebox, first day of sprint
  • PO presents PBI wishlist
  • Team discussed and negotiates
  • Team commits to the work
  • PBIs broken down into tasks
  • Team creates definition of done for the sprint
  • Sprint Goal is documented
26
Q

Sprint Retrospective

A

<=3 hours time to review and plan for improvements for the next sprint

27
Q

Sprint Review

A

<= 4 hours

Demonstration by the team for stakeholders to inspect the increment

28
Q

Technical Debt

A

Overhead of maintaining the product often caused by poor design decisions

29
Q

Describe Managing multiple Agile Teams

A

Situation - Satya Demo

  • Single Product (demo of three techs)
  • Multiple features (object recognition, voice to text, translation, etc.)
  • Seperate teams specializing in each
  • Challenge - time the release cadence

Action - Azure Teams and Shared PO

  • Seperate teams in ADO
  • Shared Product Backlog
  • Seperate Sprint Backlogs
  • Tried to synchronize release cadence

Result

  • Combined visibility and tracking for entire team
  • Seperation of concerns
  • Close Release Timing
30
Q

What are the elements of a Good User Story?

A

Follows the INVEST model

31
Q

What is INVEST?

A

Framework for writing good user stories

  • Independent - uncoupled from other stories
  • Negotiable - Teams decide how to implement
  • Valuable - Each has a unit of value to end users
  • Estimable - Easy to make time estimates
  • Small - Its lifecycle fits into a single sprint
  • Testable - Clear acceptance criteria
32
Q

What are the overall benefits of an Agile approach?

A
  • Enables adapation to changing landscape
  • Keeps teams focused on business value
  • Enables creativity
  • Inspires teams with incremental wins
33
Q

Story Mapping

A
  • Scrum tends to push teams into flat backlogs of features but we can lose perspective on the “why” of the product.
  • About “Framing the journey” with user activities (Epics) in a rough order over time that creates a “backbone”
  • User activities are refines into Tasks (stories)
  • Stories are broken down into sub-tasks
34
Q

What are the benefits of framing the journey with story mapping over just a flat backlog?

A

By starting with user activities and personas, it helps teams maintain perspective on what the successful product is meant to do.

The key benefit is that the whole team is more engaged with the success of the product.

35
Q

When does Sprint Planning Happen?

A

The first day of a new sprint

36
Q

What are the key elements of a good sprint goal?

A
  • Actual goal Statment
  • Method employed to reach the goal
  • Metrics to determine if the goal has been met
37
Q

When does a Sprint end?

A

When the timebox is done

38
Q

Does a Product increment need to be ready for release by the end of a sprint?

A

Yes. Does not have to be released but needs to be ready

39
Q

When does the next sprint start?

A

Immediately after the conclusion of the current sprint. (official Scrum)

40
Q

When is the Product Backlog Created?

A

Scrum Alliance does not identify a specific period of time

This should happen in Sprint Zero (the same timeframe the story mapping would be done)

41
Q

What events are contained in sprints?

A

Technically, all of them

  • Story Mapping (sprint zero)
  • Sprint Planning
  • Daily Scrum
  • Retrospectives
  • Reviews
42
Q

When is it OK to cancel a Sprint?

A

When the PO says the Sprint goal is obsolete. Typically, this means that the goal of the sprint no longer supports the business value initially intended for that sprint

43
Q

What is the overall purpose of the Sprint Review?

A

The Scrum Team presents the results of their work to key stakeholders and progress toward the Product Goal is discussed.

44
Q

Who are the stakeholders that are absolutely required in the sprint review?

A

Product Owner

Dev Team

45
Q

What are the key activities in the sprint review?

A
  • Adjusting the Product Backlog to meet new opportunities
  • Demonstrating the work that meets the DOD
  • Answering questions about the increment
  • Collaborating on what to do next
46
Q

What are the key questions in a Sprint Retrospective?

A

How were our interactions?

Were our processes and tools effective?

Were our DODs effective?

What changes will be most helpful?

What were the challenges and were they solved?

47
Q

Document Format for the Sprint Retrospective

A
48
Q

What should happen to work that does not meet the DOD for the current sprint?

A

It should be put back in the backlog for consideration in the next sprint
