I have experience at several companies with many different cultures, and I don't know of anyone who likes to slog through the details before getting to what the final problem or solution is. People just don't have time for that. Putting the important part first serves the dual purpose of quickly informing people who aren't interested in the details, and telling them up front why they might care about reading the details. It's like having an abstract or a blurb to briefly summarize for management. Similarly, if you need someone to take action based on the result, you don't put it at the end where nobody's going to read it. You put it at the beginning, first thing, and then build up the background.
