It refers to the number of people in your team that can get hit by a bus before your project gets stuck.
It doesn't have to be a bus, imagine illness, holidays, parental leave, changing jobs, etc.
Let's see how it happens and how to increase it 🧵
How can it happen?
- Having only one developer on the team. They build all the software and they are the only person that knows how everything works.
- Having a "rockstar" developer on the team. They build complex systems and don't tell anyone about them.

How can we increase it?
- Write documentation. Every time you create a new system or go through an internal process, if anything could be improved, take the time to go and do it.
- Regular meetups. So you can know what everyone is working on.
