Business Continuity/Disaster Recovery (BC/DR) includes the processes, procedures, decisions and activities to ensure an organization can continue to function during an operational interruption due to crises and disasters. 
A company's internal communication is central to enhanced business performance. It is the foundation that aligns the CEO and the leadership team with every manager and supervisor to connect to execute the company's vision, mission, objectives and goals. 
The demands placed on today's corporate business operations are growing, creating a situation where managers must do more with less. All areas of the business are affected and the need to stay nimble requires constant communication. 
The mission of an IT department is to deliver business-critical computer services and to ensure maximum up-time with the corporate infrastructure. Organizations need IT alerting systems to automatically notify the right people at the right time when a disruption occurs -- no matter where they are located or what communication device they have at hand. 
Enterprise Communications: Whatever the job, wherever it is, whoever's involved -- enterprise communications are all the internal and external communications required to get people together to get a job done.
