Terrorism is the great threat faced by the whole world. Metropolitan cities are under serious threats of terrorist attacks globally. The strategy of terrorist activities to imply maximum damage to country is to attack citizens and business or economic centers of big and metro cities. Recent evidences of 9/11 attack of World Trade Center (2001), Mumbai attack of 26/11 (2008), Nice attack (2016) in Paris prove the assumption. Terrorism and terrorist activities across world like suicidal attacks, bomb blast, random firing, use of vehicles for terror attacks like trucks, planes and threats of bio-weapons and nuclear weapons are few ‘T-VUCA’ factors which are completely non-business related factors. Such terrorist activities affect the businesses in drastic ways and in severe manner experiencing losses of money, men (employee and customers), asset, business and business process, market faith and reputation etc. and develop crisis alerts as well as challenges the business continuity for long time. The paper develops a case study of 26/11 attacks of Mumbai, India in 2008 and tries to see how Terrorism creates VUCA (T-VUCA).
