On 29 August, 2005 the category 5 huge Hurricane, Hurricane Katrina hit USA land. This natural disaster brought massive flood, damaging the property and resulted into high death toll. Although the projects related to the protection of areas by Hurricane were constructed 60 years ago but this exceptional unexpected disaster was the most terrible one in USA history. (GAO-06-934, 2006, pg 1).
The disaster of Hurricane Katrina was beyond the expectation of the officials of the emergency management, which resulted into delay in supporting the effected people and the area by the guards and military. This uncontrolled situation showed the absence of management and lack of the ability to take a quick action by the people responsible to handle the problem because of their unawareness of handling the situation (Cooper & Block, 2005, pg 87).
According to Professor Charles Wise, "A new organizational plan should include the integration of science and management and call for managers to change their approach as new information arrives" (2006, pg302-318).
Wise laid importance for the implication of network model rather than the hierarchical model. He explains that in hierarchical model, the decisions take place at the top level without communicating all the levels of organization and there is no evaluation of the progress. Due to this, flaws and unfavorable situations results at the end. In network model, there is continuous flow of information between the different levels of organization, which brings good results in managing any emergency. Waugh and Streib also laid emphasis on the change in the hierarchical model in which only top management contributes in making the decision (2006, pg 131-140). The failure in handling the hurricane Katrina showed the inability and flaw in the decision making of the hierarchical management (Takeda & Helms, 2006, pg 204- 217).
