Guidelines for Technical Writing


Memos
Many students have difficulty writing an acceptable memo.  Often, students are unfamiliar with the conventions for a business or engineering memo in North America.  The structure and style expected in an engineering setting in North America might seem abrupt, even rude elsewhere.  An engineering memo concisely presents your co-workers and superiors with information for decision-making and a record of your work, but it is not a diary, a log, or a story.
Below are links to memos written by students in this class as a homework assignment that received high grades.  These students have given permission for their memos to be displayed as a reference for other students.  Each memo is different, though they have similar, correct structure and style.  
(1)  Memos briefly describe the problem to be solved, the approach, and the conclusions drawn by the writer in the FIRST paragraph.  The remainder of the memo gives additional explanation / justification.  
(2)  Memos are concise.  Key information about the analytical approach is provided, NOT a step-by-step procedure.  
(3)  Sentence construction is straightforward, but not first-person.  A standard technical vocabulary is used, with no casual language.  
(4)  Quantitative information is presented (e.g., values of Cpk), but "empty" words such as "very" and "really" are not used.  
(5)  Information best conveyed graphically is displayed graphically, with discussion in the text.  For example, displaying control charts with a concise discussion conveys process behavior more effectively than a large table of numbers or a long discussion.

Course Notes  

Notes for each topic stay on the web all the time as a courtesy to past students, as they often refer back to them.  However, I may revise the notes as we reach that lecture in the current offering of the course.  I advise current students to print notes no earlier than 6 pm the day before lecture, because they may be revised.
