8. Scrum Team
● One Product Owner (representing many
stakeholders)
● One Scrum Master
●
Many Developers (7 ± 2)
9. Product Owner
● Represents all of the stakeholders - “a single,
wringable neck”
● Understands the big picture and the value each
story brings to it
● Considered the hardest job in the company (if
done well)
10. Scrum Master
● Coaches everyone on the Scrum process
● Facilitates the ceremonies
● Stats Tracker
● Impediment Unblocker
● Half-time job (if done well)
● Might also Scrum Master a second team, or
● Might also be a Developer
● Must NOT also be the PO
14. Definition of Ready / Done
● Service Level Agreements for
inbound/outbound work.
● Ready: Guarantees made to the team before a
ticket is placed in the “Ready” column for them
to pick up and process
● Done: Guarantees made by the team when a
ticket is completed.
● Done: Most importantly lists what's not done
(e.g. internationalization/localization).
16. Sprint Planning
● Story 1 (13 pts)
● Story 2 (3 pts)
● Story 3 (8 pts)
● Story 4 (13 pts)
● Story 5 (20 pts)
● Story 6 (3 pts)
● Story 7
● Story 8
● Story 9
● Story 10
● Story 11
● Story 12
● Story 12 (1 pt)
● Story 9 (5 pts)
● Story 1 (13 pts)
● Story 2 (3 pts)
Prioritized Product Backlog Sprint Backlog
During Sprint planning, the developers suggest that,
even though Story 12 is not highly valued by the PO,
it's a quick win (1 point) and something everyone can
rally around. They also suggest that Story 9 is high risk
and ought to be tackled early. The PO agrees.
All other things being equal, Stories 1 & 2 are pulled
from the top of the prioritized backlog.

As a _______________________,
I want ______________________
so that ______________________
“As an administrator, I want a way to
control which users can perform which
tasks, via roles and permissions, so
that we can pass a Sarbanes Oxley
audit.”
27. Acceptance Test
Given _______ and _______
When _______ and _______
Then _______ and _______
Given that I am logged in as an
administrator, when I create a user John,
and I create a role Clerk, and I assign the
ReconcileReport permission to the Clerk
role, and I make John a Clerk, then John
should be able to log in and print the
Reoncile Report.
31. Kanban means “Sign Board”
Kanban is an element of just-in-time (JIT)
production, as invented by Taiichi Ohno for
Toyota in the late 1940's – based on studies of
inventory systems used in supermarkets
at the time.
32. kanban card = “signal card”
“kanban” with a lower-case “K”
34. “Kanban” System
“Kanban” with a Capital “K” refers to a system
(framework) for tracking work in progress.
“Signal” Cards Work Cards
35. Kanban & Scrum Share...
● Easy to Learn the Basics
● Big, Visible Charts
● Regular Cadence
● Retrospectives (“Inspect & Adapt”)
● Cross-Functional Collaboration
● Maximizing Value (by Eliminating Waste)
● Early Feedback
● Formal Definitions of Ready/Done
36. Kanban vs. Scrum
● It's all just “Work”
● Steady “Flow” by
Limiting Work in
Progress (“WIP”)
● Measure Cycle Time
& Throughput
● “Pull” System
● Stories, Epics &
Tasks
● Incremental Delivery
via (2 week) Sprints
● Measure Velocity
● Sprint Planning/
Negotiating
37. How to Choose?
Kanban:
● Operations Work
● Software
Maintenance Work
● Coming from Rigid
Legacy Methods
(Waterfall)
● Compartmentalized,
Siloed Teams
Scrum:
● Greenfield Project
● Many Stakeholders
● Must Coordinate
Around a “Roadmap”
● Lots of Epic Stories
38. A Simple Kanban Board
Ready Doing Done
No distinction between Stories and
Subtasks. They are all just Tasks.

48. Why Limit Ready Column?
● Enforces delaying decisions until last
responsible moment
● It's how the Product Owner “negotiates” with the
team – PO (representing stakeholders) decides
what, Team decides in what order (by pull)
● Work is tracked according to the time it enters
the Ready column until it lands in the Done
column (“lead time”). A ready limit makes that
meaningful.

53. What About Story Size?
Ready (6) Test (5) Done
It doesn't seem to matter. Kanban case studies, so far,
indicate that it's much more lucrative to be concerned
with idle time between activity than the activity time itself.

Adjust them? Denote them? Track them?
54. Kanban Analysis Types
● By reflecting on outlier stories
● By looking for patterns on the Kanban Board
● By tracking cycle time
● By tracking flow

57. Possible Actions: Outliers
● Is it a problem/opportunity?
● Dig deep (“5 Whys?”) to get from the
proximate cause to the root cause
● How might the delay have been mitigated?
● Retool &/or Retrain
● Definition of Ready issue?
Definition of Done issue?
61. Possible Actions: Bottlenecks
Note: Occasional bottlenecks are good. They interject
welcomed slack time. What you want is a roughly even
distribution of slack time across the functions. If not, then ...
● Cross-functional “swarming”
● Add manpower
● Retool &/or Retrain
● (DO NOT just increase WIP Limits)
63. Possible Actions: Impediments
● Revise the Definition of Ready – Don't start the
work until you know it won't be impeded that
way
● Reassign responsibility for impediment-causing
work to the Team (i.e. make the external
resource join the team)
● (Rarely) revise the Definition of Done to exclude
the impeded work (i.e. pushing responsibility for
that part off the Team)
72. Possible Actions: Wavy Trendline
Can the hiccups be explained? If not, then...
● Smaller stories
● Reduce the WIP limits (yes, reduce)
● Attend to impediments
● Remove distractions
73. Take-Aways
All of the various Agile Methodologies attempt to...
1. Eliminate waste. They “Maximize the work not done.”
2. Only provide a framework. You must “Inspect & Adapt”
3. Only illuminate problems. There is no silver bullet.
4. Boost communication. When stakeholders and
developers are on the same page, the methodology has
done its job.
