About Bus Factor
The bus factor (also known as the "lottery factor" or "truck factor") is the minimum number of team members who would need to suddenly disappear before critical knowledge is lost. It measures your team's resilience to unexpected departures, whether from resignations, illness, promotions, or winning the lottery.
