ABSTRACT
The need to be safe, which in practice means the need to be able to operate or function with as many wanted and as few unwanted outcomes as possible, is paramount in every industry and indeed essential to all human activity (Hollnagel, 2014). It is obviously of particular concern in the many safety critical industries, where losing control of the process can lead to severe negative consequences. The examples of nuclear power generation and aviation immediately come to mind. But the need to be safe is present in all other industries as well, including healthcare and mining.
