Organisations have been urged to make sure they have strong electronic communication links in place, as London faces potential disruption from protests during the G20 meeting in Canary Wharf, says the Continuity Forum.
These systems include software for connecting remote workers to the corporate network, diverting phone calls to alternative locations, monitoring police alerts, and sending text messages to staff.
Organisations need to be proactive about ensuring systems are in place and working, said Russell Price, Continuity Forum chairman.
The Continuity Forum has been working with organisations in the City ahead of the G20 meeting and has advised them to encourage staff to work from home wherever possible.
"This is not practical for every role such as financial traders, but most other people should be able to avoid the City this week," said Price
As disruptions caused by snow earlier this year showed, organisations that had planned for remote access to corporate systems experienced the least disruption to business.
"Organisations can easily switch calls to staff wherever they are working if they have put the necessary software in place," said Price.
Well-prepared organisations will be monitoring police alerts this week and have systems in place to contact staff to warn them not to come in to work if necessary.
"Communications are often overlooked and can be difficult simply because contact numbers are not updated regularly," said Price.
The ability to gather and disseminate information is 90% of the battle in ensuring business continuity and managing potential disruptions, he said.
This includes communicating with outsourced security staff about exactly what the business expects of them in different circumstances.
During the G20 meeting, Price said organisations should follow the police example of increasing visibility to project presence and authority of internal security staff.
