What tool is commonly used for project scheduling?

A Gantt chart is commonly used for project scheduling because it provides a visual timeline of a project's tasks, showing the start and end dates, duration, and dependencies between activities. This tool is particularly effective for tracking progress over time, as it allows project managers and team members to quickly assess which tasks are on schedule, which are behind, and how they relate to one another in terms of timelines.

Additionally, Gantt charts help in resource allocation, enabling managers to see at a glance who is working on what and when. This visual representation simplifies communication with stakeholders regarding project status and timelines, making it a widely favored tool for project scheduling across various industries.

In contrast, the other options serve different purposes. PERT diagrams focus on analyzing the tasks involved in completing a project, identifying the minimum time required for each task and their interdependencies, but do not visually represent the timeline as effectively as Gantt charts. SWOT analysis is a strategic planning tool used to identify strengths, weaknesses, opportunities, and threats related to a project, while the fishbone diagram is used for identifying root causes of problems, rather than for scheduling tasks in a project.
