Business continuity planning is the process of ensuring that your organization can continue doing business even when its normal facilities or place of business is unavailable. In earlier years, many companies undertook what they called “disaster recovery planning”—which was nothing more than making sure that their computer operations could be resumed as quickly as necessary when the data center was unavailable. When companies tested their “disaster recovery plans,” some of them realized that being able to recover data center operations was all very well but pointless if the organization’s offices and other places of business-where the functions provided by the data center were used-were also unavailable.
