Abstract: Enterprises are always challenged by deciding on the cost/benefit of Disaster Recovery (DR) investment. Organizations readiness to respond to threats whether it’s natural disasters, cybersecurity, or human induced is vital for its Business Continuity Program (BCP). Therefore, training/drills/exercises provide measurable assurances that critical functions/system are resilient to unplanned incidents. IT professional though have a consensus on exercising announced drills but disagree on the value of unannounced drills. This article is an attempt to describe and examine the value of unannounced drills by using the method of doubt approach by the 17th century philosopher named René Descartes to conclude the verdict. Keywords: Information Technology, IT Disaster Recovery (DR), Controls, Critical Systems, Business Continuity (BC).
