Conciseness is not necessarily brevity. Consideration goes one step further than courtesy. The terms are not exactly synonymous. Consideration is the broader term and includes what you actually say in your message or the solution to your particular problem. Consideration is simply another name for one aspect of the you attitude , which is often discussed in relation to business letters but is also applicable to business reports and all other business messages.
Constructive writing is positive, specific, helpful, convincing, and effective.
Convincing writing is written in specific, concrete words that lead logically to a reasonable conclusion. Readers are convinced by evidence, not by persuasion. A message should be correct in information given, in the form and approach chosen, and in English usage. Being grammatically correct in every detail, as important as this feature is, is not enough for good business writing. A report that includes inaccurate, incomplete, or biased, nonobjective interpretations causes more havoc than erratic punctuation or misspelled words.
