Process analysis is a form of
technical writing
Technical writing is writing or drafting technical communication used in technical and occupational fields, such as computer hardware and software, architecture, engineering, chemistry, aeronautics, robotics, finance, medical, consumer electronics, ...
and
expository writing
The rhetorical modes (also known as modes of discourse) are a long-standing attempt to broadly classify the major kinds of language-based communication, particularly writing and speaking, into narration, description, exposition, and argumentatio ...
"designed to convey to the reader how a change takes place through a series of stages".
While the traditional process analysis and a set of
instructions are both organized chronologically, the reader of a process analysis is typically interested in understanding the chronological components of a system that operates largely without the reader's direct actions (such as how the body digests an apple), while the reader of a set of instructions intends to use the instructions in order to accomplish a specific, limited task (such as how to bake an apple pie). By contrast, the reader of a
mechanism description is more interested in an object in space (such as the form and nutritional value of a particular kind of apple).
