Pair Programming
2 likes86 views
The document discusses pair programming, a software development practice where two developers work on the same task, alternating roles as pilot and navigator. It highlights the costs and benefits, noting improvements in design quality, defect reduction, and team communication while suggesting optimal scenarios for pair programming. Various techniques such as chess clock, think loud, and pomodoro are presented to enhance the effectiveness of this collaborative approach.

C O C K B U R N “They found that for a development-time cost of about 15%, pair programming improves design quality, reduces defects, reduces staffing risk, enhances technical skills, improves team communications and is considered more enjoyable at statistically significant levels.”

- 14. C H E S S C L O C K • Ensures that will have a switch between the Pilot and the Navigator • There are tons of apps and websites for free
- 15. T H I N K L O U D • Creates a synergy between the pair • Fastest way to validate an idea
- 16. P O M O D O R O T E C H N I Q U E • Time-boxing • A way to do some personal shit (literally) • 25 minutes max of high-focused work • 5 minutes break to stretch
- 17. Y O U R I D E A F I R S T • Guarantee that there will not be a “dominant" pilot • builds TRUST • Helps to understand solutions proposed by other developers
- 18. 1 0 S E C O N D S R U L E • Makes you thoughtful • The pilot can develop his entire thinking process without interruptions
- 19. P I N G - P O N G • A fun way to practice TDD • The pair is reasoning about the code, all the time.
