Kevin Nevrous, Deloitte enterprise risk services partner, said teleworking could fit as a recovery strategy, but warned its suitability could vary depending on the type of business.

He said organizations would have to deal with issues such as virtual private networks, existing telephony infrastructure and the teleworkers' access to broadband.

"In some disaster recovery or business continuity plans, not all organizations have considered communication requirements or a secondary pipe just in case the main telecommunications pipe fell over," Nevrous said. Companies exploring the teleworking route need to determine whether they have sufficient capacity to cope and whether the telephony gateway is big enough to handle the load, he said.
