Senior managers know well that few questions have neat solutions, and are ill served if asked to settle for them. Of course, raising problems without talking about solutions is insufficient. But the solutions shouldn't be too strongly pressed. They aren't the essence of what makes people think, and can close people's minds if oversold. Getting the questions right matters more.
Clarity is also important.
Since clients can take slightly, if not amazingly, different meanings from the same material, simplicity is essential to avoid misunderstandings. Finally, there is the problem of repetition. It is a universal temptation for consultants and authors to weigh in with their opinion on a popular topic, no matter how many have done so before them. More truly can turn out to be less. So if a subject is competently handled in a technical reference, there is no reason to recite it again unless there is something new to say.
