This is an illustration of the yearly cycle for the management of a master program, with multiple circles that show what each task group is doing during each part of the year, so that everybody knows what everybody else is up to. The final result should rather look like a cycle, or rather a circle. We will need three circles inside each other: The goal is to illustrate each task that is needed for one student cohort to complete the program. In total, this is actually 3 years of work: one cohort is applying, one cohort is studying, and one cohort is finishing up left-overs in case of illness, failing classes, etc. Hence, we will need three complete circles that run in parallel. Each circle should consist of little boxes, one for each day. The academic year starts on Sep. 1, and I would like the division of Aug. 31/Sep. 1 to line up approx. with the 8 o'clock position and the Dec, 31/Jan. 1 division to line up with the 12 o'clock division. (This does not have to be perfect, and likely won't, because 122/365 is not exactly 4/12. It's more important that each day gets one 365th of the circle.)
I suggest that in the first step, you design an empty template (A3 format) with 365 days, simply black on white background, without any labeling. In the second step, we will add annotations on which activities will need to be completed at what time. This may mean that each circle will get multiple tracks (the outer circle will likely be four tracks: PR, applications, finances, program development. The middle circle will likely be five tracks: two tracks for classes, one each for exams, administration, and study advising. The inner-most circle will have one track: thesis work.
I will circulate the empty template to my colleagues who will make annotations to indicate what is happening at any time. In the second stage, the annotations should be built worked into the final version of this chart.
