The organisation should put robust systems in place for announcing and exchanging information with the workforce and with its customers, suppliers, neighbours and other interested parties, using a wide range of tools and its established platforms so that people know where to find critical information and ask questions. Two-way mass notification can be supplemented by recorded-message lines, helplines, dark-site web pages, briefings by line managers and leaders, and social media, which also reduce the flood of incoming queries. Regular reviews of communication methods should ensure the internal structure is fit for its normal task; exercise internal and external plans and systems frequently against a wide range of events, with exercises that integrate both; keep two-way tools in mind rather than one-way broadcast; explore new tools; define communication roles clearly, including leadership and line management; keep multiple methods current to circumvent technology failure; and define the internal controls and the feedback loops inside communications teams and across response teams.
