Microsoft Planner, which comes with your Microsoft 365 subscription, provides basic tools for managing tasks with three types of views: Grid, Board, and Calendar. However, it does not include a Gantt chart, which is useful for seeing project timelines and how tasks depend on each other.
If you need more detailed project management tools, like Gantt charts, you can upgrade to a more advanced version of Planner. This version includes features from Microsoft Project, offering a Timeline view (like a Gantt chart) along with the original Board and Grid views. This upgrade gives you a fuller set of tools to manage projects, making it easier to handle more complex tasks and timelines in one integrated platform.
