For many years the majority of software development followed the waterfall development model. Recently, alternatives to the waterfall model have been devised and subsequently revised in an attempt to make the process of software development more able to respond quickly to changing customer needs.
In the last few years, methodologies such as DevOps and DevSecOps have come into being, bringing even more advantages over older methodologies. In general, modern application development methodologies enable you to reduce your time to market, reduce the complexity of your projects, and ensure a high-quality experience for your users.
The information in this section of the Visual COBOL documentation is concerned with modern application methodologies in general rather than with any specific methodologies. When this section of the documentation refers to modern application development it is referring to any development methodology that aims to be more responsive to customer needs by automating the different parts of the process as well as the transitions between them.
