I recently completed a series of trainings for a trade association centered around effective leadership practices.
When we were working on the communications module, it became clear that these individuals were being asked for information multiple times which was taking them away from more important responsibilities.
Collectively we discussed why this occurs so frequently.
Was it the recipients were not listening properly?
Did they not understand some of the terminology?
Were they reading too fast and missing key points?
All agreed that it was probable that all these things were occurring but more importantly was that the recipients did not have an effective way to move data to appropriate places so in turn they kept “losing” the information.
Instead of scrolling through hundreds of emails or going through stacks of paper reports, these recipients just found it easier to request the information again and sometimes again and again and again! 
Obviously, this is a very frustrating problem with no clear solution.
One suggestion was to first ask the recipient in what form they want the information.
Not just the format in terms of bullets versus paragraphs but what are the key pieces of data that are the priorities and what are secondary.
By knowing this, then the person delivering the information can structure all of it in a more efficient manner for the receiver.
The next part is to understand what mode of communication the recipient wants it.
I admit that I prefer paper copies when reports are lengthy so that I can easily bring it with me anywhere I go, and I do not have to rely on using my laptop.
I also like to highlight and make notes in the margins when I find certain things I want to go back to in the future.
Others do not like to waste paper and/or they are just more comfortable reading it online.
The only issue is eye fatigue.
Reading long paragraphs can be very stressful to comprehend so make sure you have smaller paragraphs and if possible, images, graphs, and/or color to break the content up.
The crucial thing to remember is that you are not preparing this information for yourself but for your audience so spending the time upfront to understand their needs can save you much time on the backend.
Although this is cumbersome you may also have to keep some kind of log on how you distributed the material to certain people so when they comment they can’t find it, you can simply guide them to the appropriate email, etc.
