Onboarding New Team Members Quickly

New team member onboarding is expensive—weeks of reduced productivity for both the new hire and their buddy. Effective onboarding minimizes this cost through preparation, structure, and incremental complexity, getting developers contributing real value within days rather than months.

Best Practices

For Onboarding

1. Prepare before Day 1 — No waiting for access
2. First PR in Week 1 — Early win builds confidence
3. Progressive complexity — Small to large tasks
4. Buddy, not alone — Human support essential
5. Feedback loops — Check in at 30/60/90

Anti-Patterns

ONBOARDING MISTAKES:
✗ No access on Day 1
✗ "Read the code" as onboarding
✗ No buddy/mentor assigned
✗ First task too hard
✗ Overwhelming with information
✗ No check-ins
✗ Expecting instant productivity
✗ Outdated documentation
