Remember that process analysis essays identify and explain what steps must be taken to complete a specific process or procedure. There are two different kinds of process analysis essays: directional, which gives directions on how to do or make something (e.g. balancing a budget, planning a party, etc.), and informative, which describes how something is or was made or done or how it works.
Remember, however, that using an informative approach does not simply mean presenting information about the topic; you must provide information about some type of process so the reader has a clear understanding about how something works or was made (e.g. how a law is passed, how ice cream is made).
