What does good Pairing look like?
➔ Distraction-free➔ Collaboration➔ Sustainability (“bus factor”)➔ Fewer rabbit holes➔ Constant communication➔ Teaching/Learning symbiosis
@nerdneha

@nerdneha
Best pairing conditions?
➔ Isolated team➔ Few interruptions/meetings➔ Buy-in to execute on priorities➔ PM/Design resources available
@nerdneha
Tips and Tricks to get bu -in
➔ Select team with “all hands on deck” feature➔ Introduce concept as an experiment➔ Loop in product owner frequently➔ Release early, often, and iterate
@nerdneha
Prepair: Know the opposition
“I’m exhausted, talking so much is tiring”“Won’t the team move half as fast?”“I don’t get much value out of it”“[X activity] isn’t pair worthy”“I don’t like the inflexible schedule”“I’m always being watched”“Hard to work with someone when you disagree”“It’s the blind leading the blind”

Imposter Syndrome, defined
When it comes to your work life, it’s not a sprint, it’s a marathon. Pair to groom, grow, and share the knowledge in your team.

Reflections from a pairing noob
Feelings● Uncertainty● Worried about being a waste of time● Felt dumb● Relief that I wasn’t making decisions that are harshly
evaluated on “judgement day” (aka code review)● Felt smarter!
@nerdneha
Reflections from a pairing noob
What Helped● Structured predictable breaks ● Feedback at EOD● Positive specific feedback on how I was helpful● Talking about what we’re doing first explicitly (ex: via
TextMate)

Pairing setup: hardware/software
➔ 1 computer, 2 monitors, 2 mice, 2 keyboards➔ Mirror screens➔ Increase your font➔ Git duet-commit➔ Good IDE➔ Keycastr to see shortcut keystrokes
@nerdneha
Pairing setup: the intangibles
➔ Take turns - try ping-pong pairing or Timeout ➔ Take breaks -
◆ Bonding: ping pong, cards (set)◆ Time apart: catch up on emails/personal life
➔ Expairiment - mobbing➔ Keep an open mind

Pairing is like making a new friend: it isn’t always easy
but with patience and an open mind, it can be worthwhile.
