What role negotiates with users who might have conflicting requirements or requests for changes requiring additional time or cost?

The role that effectively negotiates with users who have conflicting requirements or requests is that of the project manager. The project manager is responsible for overseeing the project’s scope, timeline, resources, and budget. When stakeholders express differing needs or changes that may impact these factors, the project manager steps in to facilitate discussions and find a balance that accommodates users' requests while keeping the project on track.

In this role, the project manager assesses the implications of any conflicting requests, such as additional time or cost, and works collaboratively to arrive at a solution that satisfies the majority of stakeholders or helps manage their expectations. This involves strong communication and negotiation skills, as the project manager must convey the impact of changes and align everyone's objectives with the overall project goals.

While the systems analyst focuses on gathering and analyzing requirements, the business analyst identifies business needs and defines solutions, and the software developer implements technical solutions, it is ultimately the project manager who plays a crucial role in negotiating and managing stakeholder interactions around conflicting requests.
