Is there some benefit to using Agile etc for instance?
I can only guess you are not familiar with the tool, or you probably would not have asked this question. The tool is meant to keep forward momentum in a project in the most cost effective manner. (to put what I know about it in a nutshell)
There are many tools dedicated to software development, and in one way or another they are all useful. Devote some time to the research if you are serious about taking on the project. Ask questions as they arise.
