Description: The paper takes a critical stand on best ERM practices as proposed by the Cultural Theory of Risk and especially by the work of Ingram, Underwood and Thompson (IUT). The paper claims that both mainstream-type ERM practices ("rigid ERM") and IUT's alternative ("fluid ERM") fail in critical parts to account how risk managers, in everyday normal tasks, develop their ERM practices in a context-dependent way. Context-dependent ERM takes into account the whole context, that is both the recognition that risk environment changes and the need for the firm to develop a stable (yet open to meaningful changes) sociotechnical identity with a consistent risk attitude and appetite.
