“…Level 1 "Artefacts and Behavior" is reflected by the used channels of communication (face-to-face, e-mail, intranet), its dispersion (to all, only those concerned, only management), its direction and coordination (cascade top down, at once to all employee), responsibilities (centralized and coordinated by a specific unit, top management task) or feedback loops. Third, for effective internal crisis communication the practices, which fall into level 1 "Artefacts and Behavior", are largely in line with level 2 "Espoused Values" confirming previous studies [14]. New is the finding, that effective internal crisis communication is also strongly correlated to the congruence between level 2 "Espoused Values", on the one hand, and level 3 "Basic Assumptions" within the company on the other hand.…”
