Facility managers can use stack planning as an efficient way of assigning seats to entire departments rather than seating one employee at a time. The “stack” in stack planning refers to a stacked view of multiple floors in a building. The major benefit of this space planning approach is the efficiency provided by a high-level view that forgoes fine details like individual seats and people in favor of a broader approach that makes seat assignments move much more quickly. This technique also makes it easy to group departments or teams together in a way that facilitates efficient collaboration.
