About BLUF

Bottom Line Up Front, or BLUF, is the practice of beginning a message with its key information. This provides the reader with the most important information first. By extension, that information is also called a BLUF. It differs from an abstract or executive summary in that it is simpler and more concise, similar to a thesis statement, and it resembles the inverted pyramid practice in journalism and the so-called “deductive” presentation of information, in which conclusions precede the material that justifies them, in contrast to “inductive” presentation, which lays out arguments before the conclusions drawn from them.
