A high coupling is often one of the main obstacles to the growth of an application and prevents its scalability in terms of complexity. In fact, an intricate dependency graph means that every part of the system is a liability; it has to be maintained for the entire life of the product, and any change should be carefully evaluated because every component is like a wooden block in a Jenga tower, moving or removing one of them can cause the entire tower to collapse. This often results in the building of conventions and development processes to cope with the increasing complexity of the project.
