In ProServe, what is the main use of Gantt charts?

Gantt charts are primarily used to visually represent project timelines, which makes option B the correct choice. They provide a graphical illustration of a schedule, showing the start and finish dates of the various elements of a project. This visualization aids project managers and teams in understanding the sequence of tasks, their duration, and how they overlap or relate to one another over time. As a result, Gantt charts help ensure that all team members and stakeholders are on the same page regarding the project timeline and deadlines, which is crucial for effective project management.

Other uses mentioned, such as outlining project risks, tracking team performance, and allocating budget resources, do not align with the primary function of Gantt charts. While project managers might consider risks, performance, and budget within the broader context of project management, these aspects are better handled by specific analyses or tools rather than through the timeline representation that Gantt charts provide.
