PROCESS ANALYSIS






"Hey Bill, I'd like you to take a look at Mr. Gorgerise's car. He's really fuming. Says the engine's burning too much oil, running rough, and getting poor mileage. Check it out and see what you can find.";

Bill begins by removing the spark plugs, hooking a remote-control starter to the starter in the car, and grounding the ignition to prevent the car's starting accidentally. Next, he fits a compression pressure gauge into the spark plug hole by cylinder number one, starts the engine, and reads and records the pressure; then he does the same for each of the other cylinders. Finally, he compares the readings with one another and the automaker's engine specs. The verdict? An excessively worn engine that needs rebuilding. Bill has carried out a process, just one among many that fill his workdays.

As we pursue our affairs, we perform processes almost constantly, ranging from such daily rituals as brewing a pot of coffee and flossing our teeth to taking a picture, taping a compact disc, preparing for a date, or replacing a light switch. Often we share our special technique for doing something—for example, making chicken cacciatore—by passing it on to a friend.

Many popular publications feature process analyses that help readers to sew zippers in garments, build catamarans, live within their means, and improve their wok technique. Process analysis also frequently helps you meet the writing demands of your courses. A political science instructor may ask you to explain how your state's governor won nomination, or a biology instructor may want an explanation of how bees find their way back to the hive. Another instructor may call for directions relating to some process in your field—for example, analyzing a chemical compound, taking fingerprints, or obtaining a blood sample.

On the job, a greenhouse crew leader may provide summer employees with directions for planting various kinds of shrubs and flowers. A technical writer may prepare a list of steps for workers to follow when unloading a par­ticular solvent from a tank car. A Sanitation Department technician may write a brochure telling city residents how to get paper, glass, and metal trash ready for recycling.

As these examples show, a process can be nontechnical, historical, scien­tific, natural, or technical.

Kinds of Process Analysis Papers

Process papers fall into two categories: those intended for readers who will perform the process and those intended to explain the process for nonperformers. Papers in either category can range from highly technical and sophisticated to nonspecialized and simple.

Processes for Readers Who Will Perform Them. The audience for these papers may be technical and professional personnel who need the information to carry out a work-related task or individuals who want to perform the process for themselves.

A how-to-do-it paper must include everything the reader needs to know in order to ensure a successful outcome. Its directions take the form of polite commands, often addressing readers directly as "you." This approach helps involve readers in the explanation and emphasizes that the directions must, not merely should, be followed. Here is an illustration:

To prepare a bacterial smear for staining, first use an inoculating loop to place a drop of distilled water on a clean glass microscope slide. Next, pass the loop and the opening of the tube containing the bacterial culture to be examined through a Bunsen burner flame to sterilize them. From the tube, remove a small bit of culture with the loop, and rub the loop in the drop of water on the slide until the water covers an area one and one-half inches long and approximately the width of the slide. Next, reflame the opening of the culture tube to prevent contamination of the culture, and then plug it shut. Allow the smear to air dry, and then pass the slide, smear side up, through the flame of the burner until it is warm to the touch. The dried smear should have a cloudy, milky-white appearance.

Processes for Readers Who Won't Perform Them. These kinds of papers may tell how some process is or was performed or how it occurs or occurred. A paper might, for instance, detail the stages of grief, the procedure involved in an operation, the role of speech in the development of children's thinking, or the sequence involved in shutting down a nuclear reactor. These papers serve many purposes—for example, to satisfy popular curiosity; to point out the importance, difficulty, or danger of a process; or to cast a process in a favorable or unfavorable light. Even though the writers of such papers often explain their topic in considerable detail, they do not intend to provide enough information for readers to carry out the process.

Papers of this sort do not issue polite commands or address the reader as "you." Instead, the writer uses the first person (I, we), the third person (he, she, it, or some noun), or the passive voice, in which the subject of the sentence receives, rather than performs, the action, and the doer is unnamed.
