The principle of separation of concerns is used by software engineers to handle the development of complex software systems. The idea is to divide and conquer software complexity by applying principle of modularity. However, as a result of increased software size there is still a lot of overlapping concerns that span multiple modules in the software system. A concern is a system requirement or a feature that defines part of the functionality in the system. These overlapping concerns are known as cross-cutting concerns, and have been found to have detrimental effects on software systems that can lead to problems in software maintainability, reusability, and make software comprehension more difficult. Cross-cutting concerns can also cause code bloating leading to increased maintenance cost and risk of making inconsistent change to the code.

关注点分离原则被软件工程师用来处理复杂软件系统的开发。其思想是应用模块化原理来划分和克服软件复杂性。然而，由于软件规模的增加，软件系统中仍然存在许多跨越多个模块的重叠问题。关注点是系统需求或定义系统中部分功能的特性。这些重叠的关注点被称为横切关注点，并已被发现对软件系统有不利影响，可能导致软件可维护性，可重用性的问题，并使软件理解更加困难。横切关注点还可能导致代码膨胀，从而增加维护成本和对代码进行不一致更改的风险。
