  2. Research Findings to Date

    Slide 2 - Research Findings to Date

    • Strong anecdotal evidence from industry
    • “We can produce near defect-free code in less than half the time.”
    • Empirical Study
    • Pairs produced higher quality code
    • 15% fewer defects
    • Pairs completed their tasks in about half the time
    • 58% of elapsed time
    • Pair programmers are happier programmers
    • Pairs enjoy their work more (92%)
    • Pairs feel more confident in their work products (96%)
