There is a parallel to this comment that is not much thought about in mechanical CAD: some designers use tools that get the job done, but the model breaks if you look at it funny. It is all too easy to fall in this trap unless management is willing to pay for models that are maintainable and not just quickly moved out the door. Asking engineers to use the "principle of least astonishment" and develop work others can maintain is difficult at first. It's inculcating the idea of model maintainability and then supporting it against budget constraints that takes the work.
