Development methodology in relation to ColdFusion application design refers to the existence of a defined set of conventions or procedures to guide you through a development project. A development methodology might define your application’s physical file structure and might dictate what type of template goes into what folder. It might define naming conventions for your code templates and how those templates interact with each other.
There are many popular development methodologies floating around the ColdFusion development community. Any one of them might meet your needs and help you to design more scalable and easier-to-maintain applications. Understanding the approach of these development methodologies might even help you to define your own practice.
