The core feature of a process essay is a description of how you accomplish a given task. A process essay can be written on subjects running the gamut from brewing beer to writing business memos. The common denominator which exists across all process essays is that they document the process that one needs to follow so as to do a given thing or accomplish a given function. Writing a process essay is thus like writing an instruction manual for using a product or a guide for accomplishing a task through the provision of step-by-step instructions.
Writing a process essay is thus focused on a target audience and providing the list of materials needed and the steps that must be taken to produce the end-product of the process. Similar to a cause and effect essay, writing a process essay involves describing the steps that must be taken to achieve a given end-state. The steps are similar to the causes that one uses to bring about an effect when writing a cause and effect essay. When writing a process essay, you should thus be methodical in describing both what is needed to achieve the desired end state of the process, and the specific steps which must be taken so as to achieve the end goal of this process.
In writing a process essay, your professor will either provide you with a target audience or ask you to choose one. One of the keys to writing a process essay is to use a level of explanation that is appropriate to the level of understanding and knowledge held by your target audience. If you write a process essay on building a fence, you would not write it the same way for a carpenter as you would a person who has never swung a hammer in their life. Knowing your target audience and writing a process essay at the appropriate level is key to achieving the best possible grade. This is something that you will be grade on in an explicit manner when writing a process essay.
Ultimately, writing a process essay is common in an English class but can be assigned in most of the scientific disciplines as well. In an English class, writing a process essay is done to ensure that you can properly give directions regarding a given task in a clear and efficient manner. In a science class, writing a process essay is done to ensure that you can accomplish a key task, for example using a centrifuge, that is common in your discipline. The manner by which your process essay is graded will vary heavily on the basis of the type of course it is assigned for. You must thus take the type of course you are writing a process essay for seriously to get the best grade possible.
