INTRODUCTION TO TDDYYΧ

10 PRACTICES OF TDDYYΧ

▸ Help people become free from the pressures of 'getting things done'

▸ Help people fail safely

▸ Encourage people to run experiments

INTRODUCTION TO TDDYYΧ

1. FACILITATOR

▸ We just need a facilitator with TDD/Mob Programming experience to share the concept of tddyyχ

INTRODUCTION TO TDDYYΧ

2. REPEATER

▸ Depending on a single facilitator from organizers can become a single point of failure. We ask and encourage repeating participants to facilitate.

INTRODUCTION TO TDDYYΧ

3. FEELING INCOMPLETENESS

▸ Becomes good motivation for continuous learning. Software developers tend to “finish” the work. By trying a challenging problems that cannot be “finished” in time, developers get a little frustration.

▸ This leads to the continuous learning at home or at office with the colleagues.

INTRODUCTION TO TDDYYΧ

4. UPCOMING EVENT

▸ We decide the next schedule by the end of a session. “We can try again soon and we can do it better next time”

INTRODUCTION TO TDDYYΧ

5. ROTATE ROLES WHEN RED

▸ Rotate roles when in a small RED phase in a TDD cycle. This gives all participants to code. 3 to 5 is optimal team size.

INTRODUCTION TO TDDYYΧ

6. CELEBRATE FAILURES

▸ Celebrate failures. It is always fearful to fail, especially in front of people you don’t know.

▸ If you successfully failed a test, it’s a success. Celebrate the failure with applause.

INTRODUCTION TO TDDYYΧ

7. KNOWN BY UNKNOWN

▸ Known Languages for Unknown Problems

▸ Unknown Languages for Known Problems

INTRODUCTION TO TDDYYΧ

8. MAKE STRANGE

▸ Crate a team with strangers in the first session.

▸ Making cultural conflicts visible would enhance learning.

▸ For the second session, participants choose how to make a team.

▸ Continue with the first session team, create a team with colleagues/friends, or create a team with strangers again.

INTRODUCTION TO TDDYYΧ

9. AUTOMATIC GROUP FORMING

▸ Do not consume much time to create teams.

▸ Create a sequence with experience and assign teams by calling numbers is a easy and fast way.

INTRODUCTION TO TDDYYΧ

10. LET’S WAI WAI!!

▸ Waiwai「わいわい」 literally means "cheerful and noisy" in an informal way.

Make an awkward moment with strangers a little less awkward. Let’s Wai Wai!

INTRODUCTION TO TDDYYΧ

TIPS FOR CONTINUOUS PRACTICING

▸ Don’t be obliged to continue for others.

▸ Do not to try to host others. Try to host yourselves.

▸ Welcome people who want to join there.
