A

The Sprint Retrospective

The Kanban Guide (Page 7)

23
Q

What must each Kanban Team’s Workflow contain?

A
  • Defined points the SCRUM Master considers the work to start and finish
  • Definition of the individual units of customer value in the Product Backlog Items (PBI)
  • Definition of the workflow states the PBIs must travel
  • Explicit policies about how work flows in and out of each state
  • Defined work in progress will be limited
  • Defined Service Level Expectations

The Kanban Guide (Page 4)

24
Q

Where should all relevant policies or direct SCRUM Team members where to find them?

A

The Kanban Board

The Kanban Guide (Page 6)

25
Q

What is a reflection of the current health and performance of the SCRUM Team’s approach?

A

Metrics

The Kanban Guide (Page 7)

26
Q

What is the definition of Kanban?

A

A strategy for optimizing the flow of stakeholder value through a process that uses a visual, work-in-progress limited ‘pull’ system.

The Kanban Guide (Page 3)

27
Q

What is defined as “The amount of elapsed time between when a work item ‘starts’ and when a work item ‘finishes’.”

A

Cycle Time

The Kanban Guide (Page 7)

28
Q

What are the 4 basic metrics of “Flow”?

A
  • Work in Progress
  • Cycle Time
  • Work Item Age
  • Throughput

The Kanban Guide (Page 7)

29
Q

What are the two parts of the Service Level Expectation (SLE)?

A
  • A time estimate
  • A probability estimate

Example - (85% chance this item will finish in 8 days)

The Kanban Guide (Page 5)

30
Q

What is the most central concept to Kanban?

A

The “Workflow”

The Kanban Guide (Page 5)

31
Q

What is defined as “The number of work items started but not finished (according to the SCRUM Team’s definition of “Workflow”)

A

Work in Progress (WIP)

The Kanban Guide (Page 7)

32
Q

What is the Service Level Expectation (SLE) based upon?

A

The SCRUM Team’s historical cycle time, and once calculated should be posted to the Kanban board.

The Kanban Guide (Page 5)

33
Q

Does a work item have to complete each step in the “Workflow”?

A

No

The Kanban Guide (Page 4)

34
Q

Whose responsibility to ensure the continuous proactive, active, and reactive management of work items in progress?

A

The SCRUM Team

The Kanban Guide (Page 6)

35
Q

What does consistency of the Kanban team ensure?

A
  • Hyperfocus on Transparency
  • Consistency ensures integrity

The Kanban Guide (Page 5)

36
Q

What major practice does the Kanban Guide remove as part of the SCRUM Guide?

A

None - the SCRUM Guide applies in its entirety.

The Kanban Guide (Page 3)

37
Q

What is the difference between a “Pull” system and a “Push” system?

A

Pull systems trigger when the SCRUM Team starts work on an item (i.e. pulls) and only when there is a clear signal that it is time to do so. A “Push” system demands that work be started on an item whenever requested.

The Kanban Guide (Page 5 & 6)

38
Q

When the SCRUM Guide uses “Explicit” what exactly does it mean?

A

That the policies are written down or visualized somehow and that the whole SCRUM Team understands them.

The Kanban Guide (Page 6)

39
Q

What does the Work Item Aging chart show?

A

For each item on the Kanban board how long ago has it been pulled into “Work in Progress” (WIP)
