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.
