Process is a rhetorical style that provides step-by-step directions or guidance. You may encounter quite a few process essays of various types in academic writing—everything from a traditional process essay in which you choose a topic and describe the process to a lab report in which you describe the process of conducting a lab experiment.
A process essay is structured around the goal of providing the reader with directions or guidance. Most of the time, students write process essays that discuss how to do something. Process essays are the recipes or technical brochures of essay writing.
