Pourquoi la gestion de crise est un enjeu strat\u00e9gique<\/h2>\n

Une crise mal g\u00e9r\u00e9e peut d\u00e9truire en quelques heures une r\u00e9putation construite en d\u00e9cennies. Incendie, cyberattaque, accident grave, crise sanitaire ou bad buzz m\u00e9diatique : aucune organisation n’est \u00e0 l’abri. Pourtant, 70 % des entreprises fran\u00e7aises n’ont pas de Plan de Continuit\u00e9 d’Activit\u00e9 (PCA) op\u00e9rationnel.<\/p>\n\n

Erreur n\u00b01 : Ne pas avoir de cellule de crise constitu\u00e9e en amont<\/h2>\n

La premi\u00e8re erreur est de tenter de constituer une cellule de crise pendant<\/em> la crise. Dans l’urgence, les r\u00f4les ne sont pas clairs, les d\u00e9cisions sont retard\u00e9es, les ego prennent le dessus sur l’efficacit\u00e9.<\/p>\n

Une cellule de crise efficace est nomm\u00e9e, form\u00e9e et entra\u00een\u00e9e<\/strong> avant que la crise ne survienne. Elle comprend g\u00e9n\u00e9ralement : le directeur g\u00e9n\u00e9ral, le directeur de la communication, le DRH, le responsable s\u00e9curit\u00e9\/s\u00fbret\u00e9, le directeur juridique et le DSI.<\/p>\n\n

Erreur n\u00b02 : Communiquer trop tard ou trop peu<\/h2>\n

Le silence est interpr\u00e9t\u00e9 comme un aveu. Dans l’\u00e8re des r\u00e9seaux sociaux, une crise peut s’emballer en moins d’une heure. La r\u00e8gle d’or : communiquer vite, communiquer vrai, communiquer r\u00e9guli\u00e8rement<\/strong>.<\/p>\n

Pr\u00e9parez en amont un \u00ab\u00a0dark site\u00a0\u00bb : un site web dormant qui peut \u00eatre activ\u00e9 en quelques minutes pour diffuser des informations officielles lors d’une crise. C’est une pratique standard des grandes entreprises que les PME ignorent souvent.<\/p>\n\n

Erreur n\u00b03 : Confondre gestion de crise et gestion d’incident<\/h2>\n

Un incident est un \u00e9v\u00e9nement g\u00e9rable dans le cadre normal de fonctionnement. Une crise d\u00e9passe les capacit\u00e9s de r\u00e9ponse habituelles et n\u00e9cessite une organisation exceptionnelle. Activer le protocole de crise pour un incident mineur g\u00e9n\u00e8re de la fatigue organisationnelle et d\u00e9cr\u00e9dibilise le dispositif pour les vraies crises.<\/p>\n\n

Erreur n\u00b04 : Ne jamais s’entra\u00eener<\/h2>\n

Un plan de crise non test\u00e9 est un plan qui \u00e9chouera. Les exercices de simulation (table top exercise, exercices grandeur nature) r\u00e9v\u00e8lent les angles morts du dispositif : qui n’a pas le bon num\u00e9ro, quelle proc\u00e9dure est incomprise, quel mat\u00e9riel n’est pas disponible.<\/p>\n

Trigone Pr\u00e9vention recommande au minimum un exercice de simulation par an<\/strong>, avec debriefing structur\u00e9 et mise \u00e0 jour du plan.<\/p>\n\n

Erreur n\u00b05 : Oublier le retour d’exp\u00e9rience (RETEX)<\/h2>\n

Chaque crise, m\u00eame mineure, est une opportunit\u00e9 d’apprentissage. Le RETEX structur\u00e9 (\u00e0 froid, 2 \u00e0 4 semaines apr\u00e8s la crise) permet d’identifier ce qui a fonctionn\u00e9, ce qui a \u00e9chou\u00e9 et les actions correctives \u00e0 mettre en place. Sans RETEX, les m\u00eames erreurs se reproduisent.<\/p>\n\n
