Writing a Process Description
This document describes how to write a process description, a variation of the short report designed to convey to the reader how a change takes place through a series of stages. The process description examines an event over time; by contrast, the mechanism description focuses on an object in space.
Use a process description when your intended reader wants to learn about the action in question. You might use a process description to examine the photosynthesis of plants, the migration of animals, or the impeachment of presidents. When the reader actually wants to perform an action, write instructions instead (that is, a series of commands: "Insert tab A into slot B.")
In general, break the whole process up into smaller stages,
and describe each stage in order. If the process is part of a continuing
cycle (such as the evaporation and condensation of water), say so.
It is possible to write an acceptable process description that is also a set of instructions (such as a procedure for donning a spacesuit, or how to tie your shoe), but in order to emphasize your ability to write about a sequence of interconnected chronological events, you should pick for your topic events that take place regardless of the reader's actions. |
Introduction
Your introduction should be a concise paragraph that supplies a good sentence definition of the process to be analyzed. Like any technical document, it should state the scope and purpose of the paper.Defining the process for "Acid Rain: Where It Comes From, and How It Harms the Environment"
| One of the greatest environmental threats to our
nation's agriculture is the growing acid rain problem. (This introduction is too general; the paper appears to be about "threats to our nation's agriculture" instead of acid rain.) |
|
| Acid rain is one of the greatest environmental threats
to our nation's agriculture. (While this version does properly emphasize "acid rain," it merely makes a claim about the significance of the subject. We still don't know what acid rain is.) |
|
| Acid rain is environmentally harmful precipitation that forms after the combustion of fossil fuels releases nitrogen and sulfur oxides into the atmosphere. |
Stating the purpose and scope of the document
| This document describes the process in general terms, in order to demonstrate the necessity for increased government regulation in sensitive areas. | |
| This paper cites recent studies by Smith and Jones (1997, 1998) to assist EPA officials with their efforts to determine which parts of the country should be designated "at risk" or "potentially at risk" over the next five years. |
Brief Description
In another brief paragraph (or possibly the same one as the introduction), answer the question, "How does it happen?" Provide any necessary context (who or what performs the action, and under what conditions; what is its significance?). Give a concise overview of the process. This brief description should stand alone -- that is, it should not refer to details, facts, or terms that aren't explained within the summary. You will probably have an easier time writing this section if you save it until you have written out the complete description. Conclude this section by breaking the process up into stages: "The principle stages of writing process are planning, drafting, revising, and proofreading." Then, focus on each step in turn.Step-by-step Description
For each step in your description, write a miniature process description:- define the step
- state its purpose (or function within the process)
- providing the necessary context, and
- include brief mechanism descriptions for any components that may be involved
Conclusion
Without being excessively redundant, review the major steps in the process. Walk the reader through one complete cycle, emphasizing how the completion of each stage contributes to the final overall effect.Dennis G. Jerz
