Answer :
An organizational structure defines how activities such as task allocation, coordination and supervision are directed toward the achievement of organizational aims. I think it depends much on the work itself, it does not matter whether it is a descriptive essay or a comparative. However, if you are not that good at building the structure of your work, ask the writers from "Marvelous Essay" to show you the good example of it. I frequently use them and I am happy about my orders.
