Process analysis
Process analysis is a form of technical writing and expository writing "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, while the reader of a set of instructions intends to use the instructions in order to accomplish a specific, limited task. By contrast, the reader of a mechanism description is more interested in an object in space.
