Engineering Onboarding Program

Why this works
The first-commit milestone target (first meaningful contribution to the codebase within a defined timeframe) is the single most important indicator of onboarding effectiveness for engineers because it represents the transition from receiving information to producing value. Buddy and mentor assignment for the first 90 days acknowledges that technical knowledge is transferred through relationship and context, not documentation alone. The feedback loop at 30, 60, and 90 days enables iterative improvement of the programme rather than waiting for exit interviews to discover what wasn't working.
Risks & review
Engineering onboarding programmes that set unrealistic time-to-productivity expectations will cause new hires to feel inadequate when they're actually performing normally. Calibrate milestone timelines against the actual time it took recent successful hires to reach productivity, not against aspirational targets. Also ensure onboarding is adapted to remote versus in-person — remote engineers need more intentional connection-building, while in-person engineers benefit from more spontaneous knowledge transfer.
