And then start solving each small issue one by one. Coupling is the act of joining two things together. Software engineering was introduced to address the issues of low-quality software projects. Problems arise when a software generally exceeds timelines, budgets, and reduced levels of quality. For instance, in a tightly-coupled architecture, each component and its associated components must be present in order for code to be executed or compiled. While the software is being conceptualized, a plan is chalked out to find the best possible design for implementing the intended solution. For example, in highly cohesive systems, functionality is strongly related. Coupling is measured by the number of relations between the modules. In loosely coupled systems, on the other hand, individual modules can be studied and altered without the need of taking into account a lot of information from other modules. 5.
