Gathering everything in one place
OneNote's easy drag and drop interface on the desk top coupled with the ability to duplicate pages is making the gathering of relevant information into one spot easier and cleaner. By creating a section in a notebook for all the transfer notes I am able to pick and chose what needs to be shared and what doesn't, all while retaining the original copies for reference.
Grouping and organizing
By taking content as pages in the section, I can drag and drop the order of the pages far easier than I could cutting and pasting in something such as Word. Images, notes, diagrams, etc. are all treated equally. It really is like organizing the chapters of a book more than it is reworking work notes.
Outputting for sharing
Since the notes are all winding up in one section, they can now be output as their own OneNote notebook (something I would use if the recipients were more comfortable with OneNote), as a Word document, or as a PDF file. Whatever works best is now a clean, organized deliverable.
Something to think about
It's important when using tools such as OneNote for note taking over an extended period of time to take into consideration not how easy it is to capture information but rather how easy it will be to retrieve that information and share it with others.
