How can it be advantageous to the developers? | Agile Testing Questions

Technically the agile methods implement a iterative and incremental development phase in the project. This means the developers have higher control over the design/code that is under development. This can be helpful in maintaining a confident mindset among the team members. Also the smaller units of development can bring in the much needed modularity in the product, making it more reusable than the traditional methods can offer.
