Tactical planning translates the “anonymous” number of people of the capacity plan to real people, in other words, to a roster. The roster assigns people to shifts over several weeks. A shift is a recurring sequence of days and time slots per day.
In the following sample, we have three shifts: Early, Late and Night.
People rotate shifts, for instance: one week Early, one week Late, and one Week Night.
Breaking it down to days allows for managing daily deviations, like off-days or sick leaves.
