   * [[Information Expert]]: Adhering to information expert means that a module only has responsibilities which belong together. So this increases cohesion.   * [[Information Expert]]: Adhering to information expert means that a module only has responsibilities which belong together. So this increases cohesion.

-  * [[Low Coupling]] (LC): A system consisting of one single module has a very low coupling as there are no dependencies on other modules. But such a system also has low cohesion. The other extreme, very many highly cohesive modules, naturally has a higher coupling between the modules. So here a compromise has to be found. +  * [[Low Coupling]] 
-  * [[Encapsulate the Concept that Varies]] (ECV): Adhering to HC often results in modules to be split up into several more cohesive ones. ECV gives further advice on how to do that.+  * [[Principle of Least Surprise]]
