There's a common assumption that offshore development inherently raises bus factor risk. The data tells a more precise story, and it's worth getting right, both as someone who might work offshore and someone who might hire offshore talent.
A single local developer and a single offshore developer create the exact same bus factor: 1. The underlying risk, one person holding all critical knowledge, doesn't care about geography.
What does change with offshore arrangements is the cost of recovery if that person becomes unavailable. Time zone gaps, weaker communication rituals, and slower context transfer can turn what would be a normal handover into a much slower reverse-engineering exercise. This is a structural risk multiplier, not an inherent property of offshore work.
The comparison, concretely:
Single Local Developer
Bus factor: high risk
Recovery: difficult, but in-person handover may help
IP/legal: usually easier to enforce locally
Single Offshore Developer (no process)
Bus factor: high risk + coordination risk
Recovery: often slower (weak documentation + timezone friction)
IP/legal: can be slower and more expensive across jurisdictions
The mitigation isn't "avoid offshore." Many offshore teams and agencies are excellent, often more disciplined about documentation than solo local hires, because process is how distributed teams function at all. The mitigation is: never make any single person, regardless of location, the only map to your system. Team-based delivery, overlapping hours, recorded walkthroughs, and documented handover processes matter more than where someone is sitting.
Geography is a risk amplifier when structure is weak. It is not the root cause.
