In a BPMN 2.0 workflow design, a gateway is used to manage the flow of execution and is also capable of executing services needed to generate output. In a customized workflow, AOP can be used as a gateway protocol, wherein it can determine the request flow after every user task. Some @Aspect classes can have heavy implementation and some may have lighter tasks depending on the workflow specifications. By knowing the repercussions of using AOP in creating software, designers can avoid overlaps and gaps between concerns and advices. Also, @Aspect implementation must not cause degradation to the performance of the application; thus, it must focus on the lighter concerns of the specification.
