Revise, as boundaries can be defined as redrawing the boundaries of something. This term is often used in the context of politics, where countries or states may need to REDRAW their borders in order to better reflect the current population or political situation. It can also be used in other contexts, such as when a company needs to REDRAW its organizational structure or when an artist needs to REDRAW the lines of a painting. In all cases, it involves making changes to the existing boundaries in order to create a new and improved version.
