What does a bar chart scheduling method illustrate?

A bar chart scheduling method effectively illustrates both the activity duration and the sequence of tasks involved in a project. This visual representation allows project managers and stakeholders to see how long each task is expected to take and how tasks are interconnected in terms of their start and finish dates. The horizontal bars represent the duration of each activity, while the arrangement of these bars visually conveys the sequence, highlighting which tasks need to be completed before others can begin. This method is particularly useful for tracking progress and ensuring that deadlines are met throughout the course of the project.

Other options do not capture the full scope of what a bar chart provides; for example, merely showing total project cost, daily labor hours, or material delivery dates does not reflect the comprehensive scheduling aspect that a bar chart offers.
