I use this yearly overview with each department to allow them to plan when to teach the content of the course.
I refer to the overview in Departmental meetings to check with departments what they are currently teaching how the pace of the course is going. The yearly overviews can be changed as the course is being taught, depending on the progress of the class.
It is a good idea to give the overviews to each department a few months before the start of the course so that they can plan for the course and take into account the pacing of previous years.
The example yearly overview below is taken from the DP Biology course 2017-2018
