Right Thing

Early testing = faster product iterations
Favorite strategies
Story Mapping practice session
Example Mapping practice session

Why test early?
Explore assumptions
Clarify expectations
Identify gaps in flow
Discover the ‘right thing’ to build

Ask testing questions early
Does this thing do what I want it to do?
Is the thing I want it to do the right thing to do?
What are the unexpected things that can happen?
What are the undesirable things that can happen?
What are the happy accidents?
Testing is THINKING.

7 Product Dimensions

Invite yourself to a … Conversation.
A story is an invitation to a conversation.

ATDD/BDD/SpecByExample
Goal of common understanding
As a Super Bowl viewing
party planner,
I want to invite only Broncos
fans,
So that we can all cheer for
the Broncos.
Given that all of my friends
are Broncos fans,
When I invite guests to a
Super Bowl viewing party,
Then I invite all of my friends.

Given-When-Then scenarios
(state-action-result)
‘Executable specification’ via Cucumber

Story Mapping Jeff Patton, User Story Mapping
Story - tells a “lower case s” story about someone doing
something, and why
Story Map - tells the bigger story of a product or
feature
We are storytellers.

Story Mapping Jeff Patton, User Story Mapping
Organizes stories to show the big picture
Goal - The thing you want to accomplish
Activities (biggest pieces)
Tasks (or steps)
Sub-tasks (smallest bits)

Story mapping de-brief
What was easy? Hard?
What would you approach differently next time?
Would story mapping work for your team?
How can your team incorporate story mapping?

Example Mapping
Question
Rule
Example
User
Story
The user story under discussion, new stories
discovered during discussion
Questions that cannot be answered by anyone in
the session
Known rules or acceptance criteria
Examples that illustrate the rules

Example
What if there are more
than 12 NYC
attendees?
Meetings with more
than 2 NYC attendees
need a meeting room.
A meeting with less
than 3 people can be
in the Green Sauce
meeting room.
Schedule a
team meeting
Remote attendees
must have a video
meeting link.
Meetings are within
normal work hours
for all attendees.
A meeting with 2
NYC and one Ukraine
people has a zoom
meeting number.
NYC and Ukraine
team members meet
at 9 am EST.
NYC and West Coast
team members meet
at 3 pm EST.
A meeting with 4
people must be in the
Bacon Cheeseburger
meeting room.
What if we have more
than 5 concurrent
distributed meetings?

Example mapping hands-on
As a host of a Super Bowl party, I want cheap, fast food delivery, so
that my guests can eat hot food and I can save money.
Pick a partner table group.
Take 3 blue cards. These are the business rules for our story.
Write 3 (and only 3) examples on the green cards (1 per card) to
illustrate those rules.
You have 2 minutes.

Example mapping hands-on, cont.
Partner table --
Guess the rules based on the examples you received (green cards) –
write them on blue cards, and pass them back. You have 2 minutes.
Table 1 -Label each rule as yes or no - yes if it matches, no if it
doesn’t.
Let’s stop and reflect.

Example mapping de-brief
What did this exercise show you?
What did you learn?
Are rules or examples better?
Why or why not?
