A healthy product company is, confusingly, one at odds with itself. It has a healthy part that is attempting to normalize and to create predictability, but it needs another part that is tasked with building something new that is going to disrupt and eventually destroy that normality. Failure to create some form of predictability will result in chaos. Failure to create some sort of well-maintained barbaric chaos inside the company guarantees that a fast-moving, ambitious, risk-taking, and ruthless someone else—someone outside the company—will invade, because they know what you forgot: hacking is important.
