What do you think? • Do you work like this? • Faster or slower? • Better code or worse? • Other effects?

Demonstration

What to watch for?

If you’re a project manager

If you’re an architect

If you’re a developer

If you’re neither

Please: • Talk about what you see to the person next to you (whisper) • Tweet to @jhannes and @Oleg. Smirsky

What did you see?

What did you see? • How often did we switch ”driver”? • Effects of pairing? • What did the ”non-driver” do? • How do you expect it to be different?

What do you think? • Pairing two seniors? • Pairing two juniors? • Pairing senior and talent? • Pairing senior and junior?

What did you see? • How many tests? • Was the step size right? • What was the first test? • How did we decide next test? • What was the final test?

What did you see? • Did we refactor the right amount? • How long was the code red? • Strengths in final design • Weaknesses in final design • Enough comments?
