$$BGRS is currently in the concept development stage. As part of the scope of BGRS there will be some integration and validation and verification, which will mitigate the risk of not meeting user requirements. To accomplish this, there will be prototyping, and demonstrations provided to users. A large component of the concept phase will be the development of software to test and demonstrate the capabilities of the system. An iterative approach will be used to refine the user interface, which is a key trait of the Agile approach. Therefore, BGRS will use the Agile methodology.$$

Do you think agile is the best approach for this type of project? Please support with a comprehensive explanation. Thanks!
