Write and present persuasive reports

Two crucial aspects of creating persuasive reports are (1) knowing and expressing the main message (if you were to meet one of your readers face-to-face, what would be the first thing you'd tell him?) and (2) organizing the material in a logical, complete, thought sequence. The report can be a figurative pyramid of progressively involved detail with conclusions and recommendations up front (at the top) followed by methods, explanations, proofs, data, etc. Critical revision and refinement must precede the finished product.
