There is nothing special about bugs that makes them automatically more important than everything else. The mere fact that something is a bug does not give us an excuse to interrupt ourselves or other people. All software has bugs. The question is: how severe are they? If we’re in a real crisis—data is being lost, the app is grinding to a halt, or a huge swath of customers are seeing the wrong thing—then we’ll drop everything to fix it. But crises are rare. The vast majority of bugs can wait six weeks or longer, and many don’t even need to be fixed. If we tried to eliminate every bug, we’d never be done. You can’t ship anything new if you have to fix the whole world first.
