I learned this by observing wear patterns, in foot traffic routing these are called "desire paths." You can also see them in wear patterns on old handles and stairs. Hence why I think before you try and change a system it's important to know what your baseline outcomes are and then instrument the system to measure where these "desire paths" exist in complex systems like computing.
