Your first step in preparing the report is reminding yourself of the client’s situation, specific request, and goal or purpose for your technical work. You may write the introduction to the discussion of such a report right away, even before you actually begin the technical work. Preparing the introduction to the discussion at an early stage helps you clarify your work schedule, identify specific criteria for testing solutions, and uncover any tasks or components needed in the technical work that require special scheduling or collaboration with other people.

In an unfamiliar or non-routine situation, you might want to send an e-mail to your manager or supervisor at this point, making sure that you’ve converted the client’s request into the appropriate and specific technical objectives. Clients sometimes are vague or imprecise in their requests, saying, for example, “get me all the information you can on an electronic transfer system that will speed up the processing here.” You might spend hours of time unnecessarily if you searched for “all the information” when a much more limited software solution was appropriate. Sometimes you will need to obtain more information from the client, such as the sizes or model numbers of equipment in its existing system with which your recommendations must be compatible.

After you have applied the criteria appropriate for the comparison to the possible solutions, decide which option meets the most criteria without failing some critical condition. Before writing, many engineers like to make a table showing the criteria in one column and the data for each option in parallel columns that allow easy visual inspection. Putting the most critical criteria or the “must haves” at the top of the column can facilitate visual scanning. A familiar example of this type of table is the kind that testing organizations such as Consumer Reports prepare with either symbols or numerical data. Occasionally a device will pass all the tests but one–such as the device may not work in a corrosive environment or it may be too costly or it may not be available in time for the project. If the failure is critical, you will need to mention it in your report.

In industry, managers usually want to know the outcome or “bottom line” solution right away, so engineers discuss the recommended solution first, followed by the reasons and evidence for that choice. Next, the engineers explain why other options were not chosen and refer to the decision table in the appendix. The comparison of solutions may be organized in either of two patterns described below, but it is more common to use an “All about A” pattern in which the engineer provides a more detailed discussion of the recommended choice and a less extensive discussion of the other options.

International Tip: However, in some countries and in companies that share a non-US culture, recommendations occur only at the end of the report, after all the data have been presented. Mexican firms and other Latin American firms that have not switched to a US-based report style may prefer complete presentation of the data before conclusions are drawn. Since this is a period of rapid globalization, you cannot count on applying stereotypes in international business. You can make the right organizing choice either by looking at reports from the client to determine that firm’s preferences in organization or by asking for advice from your manager.

All comparisons can be grouped into two types: Those that are organized around individual options (“All about A, All about B, and so on”) and those organized by criteria, points, or bases of comparison (“Point by Point”).

Summarize the outcome of your analysis and add any comments that may be needed for the reader to act on your recommendation, such as how to contact you if there are questions, any suggestions about implementation (for example, “these prices are expected to be good only through September 31st”), or recommendations for future testing or analysis.

Read through your report and write a brief form of it as a summary. Include just enough background to remind your readers of the situation that required your work. In some companies, a reference to the project title or the project number and a phrase about the work done, “Flowmeter Comparison for Rice University,” may be enough. The summary may then begin with the specific claims about what you did. If the report is going to a client, a slightly more lengthy and formal statement of the request for your work may be needed. Include a summary statement of work done, for example, “We evaluated four samples of the product in two-week and four-week trials.” Present your conclusion and add the recommendation, if appropriate. Include any key information the reader needs to take timely action, such as, “If you approve this choice, please contact Jane Jenkins in purchasing to submit the order before the price change goes into effect.”

Use a title page (if the report is going outside the company) or appropriate headings (for example, memo headings if the report is to be submitted inside the company). Reports are sometimes sent from one company to another company, in which case the engineer may be writing for a manager or company official’s signature. In that situation, the engineer may be referred to as the contact person or the preparer of the report. If the report is to be sent outside the engineer’s company, transmittal information may include

If the report is to be submitted to a manager inside the company, addresses may be omitted, and in the most routine situation, no more than the usual memo or e-mail heading will be used. Some companies have templates in their document management systems that require specific information in addition to ordinary e-mail, such as version numbers and approval spaces.

Proof-read the entire report not only to check for grammatical correctness and stylistic consistency (Did you use the same type of heading for all equivalent sections? Did you switch from bold to italic unintentionally?) but also to ensure that your conclusions really match the criteria for choosing a solution and that you have supplied sufficient information to support your conclusion. Many people discover errors or clumsy sentences by reading the report aloud at this point. Make any final corrections and submit your report with confidence.
