Our most egregious flow currently is 104 steps (it's used for server provisioning and interacts with an API, request management, and change management). While I am able to create a multi-page print-out pdf in normal view by using CTRL+A and CTRL+P, it's not pretty. I also have to use landscape view in order for my notes and actions to not get cut off horizontally. Diagram View would be much more user-friendly for my clients, but it does not allow you to highlight or select all (CTRL+A), so when you print the page it only captures what is visible in your window. Because Diagram View seems to prefer organizing flows vertically, this means that with the png download you can only get about 25 steps or so in a single file; even less with printing the browser page (depending on your resolution).
The way I would use a Visio export is by sending it to my clients. Our company uses Visio heavily and I know my clients would absorb the information better in a familiar program. My organization is experiencing a fair amount of turnover and re-orgs and many of my clients are wanting to better understand the fulfillment processes they are inheriting. Having a clean, user-friendly diagram to send them of their Flows would be extremely helpful. I also was planning on using diagrams as a part of a routine audit process to ensure my clients are reviewing their existing Flows periodically to ensure they are still correct/optimal.
