Why Pair Programming?

Pair programming is a disciplined collaboration technique where two developers work together at one workstation—one acting as the Driver, the other as the Navigator. It accelerates learning, improves design, and reduces defects early.

Benefits

• Continuous Review: Code is reviewed as it's written, lowering bug density.
• Skill Transfer: Practices and domain knowledge flow naturally between partners.
• Improved Focus: The social contract reduces distraction and multitasking.
• Better Design: Two perspectives reduce over-complication and dead ends.
• Confidence in Changes: Risky refactors feel safer with a second brain engaged.

When Pairing Excels

• Refactoring or improving legacy code.
• Fixing production incidents quickly and safely.
• Onboarding a new engineer to codebase and conventions.
• Implementing features with tricky business rules.

Common Objections

• “It halves productivity.” Most pairing benefits come from reduced rework, fewer defects, and faster alignment—not raw keystroke volume.
• “It's exhausting.” Rotate pairs and take intentional breaks; treat pairing like an athletic activity.

Pair vs Mob

Mob programming scales the collaboration to the whole team for complex, ambiguous, or high-risk work. Pair programming remains ideal for focused implementation once direction is clear. Many teams spike solutions as a mob, then split into pairs for execution.

Getting Started

1. Pick a task slightly above one person's comfort zone.
2. Decide initial roles (Driver/Navigator) and switch every 15–30 minutes, or when a logical unit completes.
3. Keep discussions high-level while driving—capture deeper debates for brief pauses.
4. Retrospect at the end: What energized? What drained? Adjust tomorrow.

Pair programming is a foundational practice that unlocks collective ownership, higher quality, and faster learning loops. Combine it with mob sessions for maximum team impact.
