The symbols in their agreed meanings.
A decision is a diamond, a document has a wavy edge, a database is a cylinder, an off-page link says where the process goes on. The flowchart symbols mean what everyone in the room already reads into them, so the argument is about the process and not about the drawing.
A step opens its own board.
Brew carries a green dot: under it is the bar's own flow — pull the shot, steam the milk, oat or not, pour, hand it to the pass. The order's process stays one screen long, and the barista's detail is one click down.
Swimlanes are one figure.
What stalls work is rarely a step; it is a handoff, and a handoff only shows when the picture says who owns which step. The lanes here are bands of one figure rather than loose rectangles lined up by hand: their names are a field, their widths are stored on the drawing, and dragging a divider re-weighs them without moving anything placed in a lane.
Every figure, named.
The toolbar's own names — what you pick is what this list says: three groups, 25 figures.
