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.


Table 7.1 lists many of the most common types of technical reports and their functions:

Report Type

Report Function

1. Laboratory Report Communicates the procedures and results of laboratory activities
2. Research Report Studies problems by developing hypotheses, collecting and analyzing data, and indicating findings or conclusions
3. Field Study Report Describes one-time events, such as trips, conferences, seminars, as well as reports from offices and industrial plants
4. Progress Report Monitors and controls production, sales, shipping, service, or related business process
5. Technical Report Communicates processes and products from a technical perspective
6. Financial Report Communicates status and trends from a financial perspective
7. Case Study Represents, analyzes, and presents lessons learned from a specific case or example
8. Needs Assessment Report Assesses the need for a service or product
9. Comparative Advantage Report Discusses competing products or services with an analysis of relative advantages and disadvantages
10. Feasibility Study Analyzes problems and predict whether current solutions or alternatives will be practical, advisable, or produced the desired outcome(s)
11. Instruction Manuals Communicate step-by-step instructions on the use of a product or service
12. Compliance Report Document and indicate the extent to which a product or service is within established compliance parameters or standards
13. Cost-Benefit Analysis Report Communicate costs and benefits of products or services.
14. Decision Report Make recommendations to management and become tools to solve problems and make decisions
15. Benchmark Report Establish criteria and evaluate alternatives by measuring against the establish benchmark criteria
16. Examination Report Report or record data obtained from an examination of an item or conditions, including accidents and natural disasters
17. Physical Description report Describe the physical characteristics of a machine, a device, or object
18. Literature Review Present summaries of the information available on a given subject

Reports vary by size, format, and function, but they are typically organized around six key elements:

      1. Whom the report is about and/or prepared for
      2. What was done, what problems were addressed, and the results, including conclusions and/or recommendations
      3. Where the subject studied occurred
      4. When the subject studied occurred
      5. Why the report was written (function/purpose), including under what authority, for what reason, or by whose request
      6. How the subject operated, functioned, or was used

Pay attention to these essential elements when you consider your stakeholders (those who have an interest in the report). That may include the person(s) the report is about, whom it is for, and the larger audience of the business, organization, or industry. Ask yourself who the key decision makers are who will read your report, who the experts or technicians will be, and how executives and workers may interpret your words and images. While there is no universal format for a report, there is a common order to the information. Each element supports the main purpose or function in its own way, playing an important role in the representation and transmission of information.

Checklist for ensuring that a report fulfills its goals:
    1. Report considers the audience’s needs
    2. Format follows function of report
    3. Format reflects institutional norms and expectations
    4. Information is accurate, complete, and documented
    5. Information is easy to read
    6. Terms are clearly defined
    7. Figures, tables, and art support written content
    8. Figures, tables, and art are clear and correctly labeled
    9. Figures, tables, and art are easily understood without text support
    10. Words are easy to read (font, arrangement, organization)
    11. Results are clear and concise
    12. Recommendations are reasonable and well-supported
    13. Report represents your best effort
    14. Report speaks for itself without your clarification or explanation
