This SmartArt graphic uses a layout from the List type. The graphic keeps the vertical list idea but breaks the general concepts, shown in the shapes on the left, apart from the details — reserved for the longer shapes, with smaller text, on the right.
List layouts are typically for items that you want to group but which don't follow a step-by-step process.
To keep text size readable, you'll want to limit the amount of text you put in the shapes within the graphic.
