Hi
A few reasons - not everyone is a licensed user and while I can give them access to a calendar, it’s not always easy for them to access it or know what they are looking at. And also, I like to print it when we have meetings about upcoming projects because we shuffle due dates of projects A LOT and it’s much easier to make a note on a printed calendar than trying to write out notes when 10 project deadlines change and try to decipher it all after to update all 10 projects with the new due dates. It’s too cumbersome to try to edit a project’s deadline during the meeting while everyone waits quietly, change the dates, go back to the calendar, etc. And finally, when planning for the long term (ie when I’m setting a project schedule for next year) it Is much better to print out the whole year to have a view of what we’ve done, and so can plan what we are going to do in the future, than to try scrolling around a screen (especially when the months are hard to see). I generally keep a printout of the last 2 years on my desk for easy reference to easily look up when was the last time we did a certain set of projects. This is because cadence is important for what we do. We schedule to release certain things once a week, or once a month, and so the visual of when each set of projects is in market makes planning easier.
Hope that explains it.
