There are a few key reasons to hire a waterfall developer: - They have experience working in a traditional, linear development environment and are comfortable following strict processes and procedures. - They are typically very detail-oriented and organized, which can be helpful in ensuring that all aspects of a project are accounted for. - They usually have strong communication skills, since they need to be able to clearly convey information about the project's progress to those who may not be familiar with the details of its inner workings.
