Responsibility without Monopoly

[No role] requires exclusive control over the domain in question. The issue manager does not prevent other people from making changes in the issues database, the FAQ manager does not insist on being the only person to edit the FAQ, and so on. These roles are all about responsibility without monopoly. An important part of each domain manager’s job is to notice when other people are working in that domain, and train them to do the things the way the manager does, so that the multiple efforts reinforce rather than conflict. Domain managers should also document the processes by which they do their work, so that when one leaves, someone else can pick up the slack right away.
