CH 7: Technical Reports

What Is A Report?

Reports are documents designed to record and convey information to the reader. Reports are part of any business or organization; from credit reports to police reports, they serve to document specific information for specific audiences, goals, or functions. The type of report is often identified by its primary purpose or function, as in an accident report, a laboratory report, a sales report, or even a book report. Reports are often analytical, or involve the rational analysis of information. Sometimes they simply “report the facts” with no analysis at all, but still need to communicate the information in a clear and concise format. Other reports summarize past events, present current data, and forecast future trends. While a report may have conclusions, propositions, or even a call to action, the demonstration of the analysis is the primary function. A sales report, for example, is not designed to make an individual sale. It is, however, supposed to report sales to date, and may forecast future sales based on previous trends. This chapter is designed to introduce you to the basics of report writing.

Types of Reports

Reports come in all sizes, but are typically longer than a page and somewhat shorter than a book. The type of report depends on its function. The function of the report is its essential purpose, often indicated in the thesis or purpose statement. The function will also influence the types of visual content or visual aids, representing words, numbers, and their relationships to the central purpose in graphic, representational ways that are easy for the reader to understand. The function may also contribute to parameters like report length (page or word count) or word choice and readability. Focusing on the content of your longer business documents is not only natural but necessary because doing so helps ensure complete, correct information.

Reports vary by function, and they also vary by style and format. This chapter discusses reports in general terms, focusing on common elements, while also examining a few of the most common types of reports prepared by technical writers. Referencing similar documents or specific report examples may serve you well as you prepare your own reports.

Informational or Analytical Report?

There are two main categories for reports, regardless of their specific function or type. An informational report informs or instructs and presents details of events, activities, individuals, or conditions without analysis. An example of this type of “just the facts” report is a police accident or a workplace incident report. The report will note the time, date, place, contributing factors, like weather, and identification of those involved. It does not establish fault or include judgmental statements. You should not see, for example, “Driver was falling down drunk” in a police accident report. Instead, you would see “Driver failed sobriety tests and breathalyzer test and was transported to the station for a blood sample.” The police officer is not a trained medical doctor and is therefore not licensed to make definitive diagnoses but can collect and present relevant information that may contribute to that diagnosis.

The second type of report is called an analytical report. An analytical report presents information with a comprehensive analysis to solve problems, demonstrate relationships, or make recommendations. An example of this report may be a field report by a Center for Disease Control (CDC) physician from the site of an outbreak of a virus, noting symptoms, disease progression, steps taken to arrest the spread of the disease, and recommendations for the treatment and quarantine of subjects.
