A bar chart schedule is a visual representation of a project timeline that displays activities along a horizontal timeline. While it is effective for illustrating the time frame and general sequence of tasks, one significant limitation is that it does not capture the interrelations or dependencies between these activities.

This means that while you can see when tasks start and finish, the chart fails to show how one activity might affect another. For instance, if Task A must be completed before Task B can begin, a bar chart will not clearly illustrate that dependency. This lack of detailed information can lead to misunderstandings in project planning and execution, as project managers and teams may not recognize critical paths or sequences that need to be respected to ensure the project stays on track.

In contrast, ease of interpretation, ease of preparation, and presenting information at a summary level are typically advantages of bar charts. They are generally easy to create and understand, making them useful for communicating project timelines to stakeholders who may not be familiar with more complex project management tools. However, the critical aspect of interactivity and the relationships among tasks is not adequately conveyed through a simple bar chart, hence highlighting this limitation.
