What is Business Continuity Solutions ?

Simply put, a Business Continuity (aka, BC) solution is based on a plan πŸ™‚
A BC plan is a predefined approach and procedure for how a business will continue to run when dealing with an emergency.

In another words, it is a process of creating systems of prevention and recovery to deal with any potential threats to your company.  These threats could be a natural disasters, such as hurricanes, fires, floods, power outages or an unintended misconfiguration of a system. It could also be a malicious cyberattack as well.

There are many benefits provided by BC planning and Disaster Recovering (aka, DR) planning to your organization when they are drafted and approved across the board, such as:

  • Improved decision-making
  • Risk Management
  • People and Property Protection
  • Morale boost πŸ™‚

The “Morale boost” element is very important piece, because when employees know plans are in place, they may feel safer. Moreover, it does not just boost morale, but potentially increases the business value perception to customers who recognize the high preparedness and responsibilities of the company.
