bus factor
What is the bus factor?
The definition
The bus factor is the number of people who can disappear before your product is no longer maintainable. One developer who knows the code means a bus factor of 1: your company depends on one person being available.
Why it matters to you
A bus factor of 1 gets paid for at the worst moment, never the best.
It’s fixed by documentation and sharing knowledge, not by trust.
It’s the first question an auditor asks before a fundraise.
A real-life example
A software company discovered its bus factor the day its developer stopped answering. The product still worked; nobody could change it anymore.
And in your case? ?
Thirty minutes on a video call to look at your product and tell you what we think.
