The key objective of the development process is to ensure a scalable, maintainable, and high-performing application. The following diagram shows the critical steps for the development process while developing customizations for Dynamics AX:
The first step of the development process is conceptualizing the application. You must understand the problem that you are trying to solve. At this stage, you need to identify the where and the what—where in the standard flow do you need to add your code, and what code can be reused from the standard one.
Dynamics AX provides numerous application frameworks and patterns that can be reused when developing any new functionality or extending any existing functionalities. If you do not understand the existing application pattern and frameworks, you may create a functionality that was not necessary, or one that already exists in the application.
