Gantt charts:
Gantt chart is a type of bar chartthat illustrates a project schedule, named after its inventor, Henry Gantt
A Gantt chart is a project management tool that assists in planning and scheduling projects of all sizes, although they are beneficial for simplifying complex projects.
This chart lists the tasks to be performed on the vertical axis and time intervals on the horizontal axis. The width of the horizontal bars in the graph shows the duration of each activity.
This chart is constructed to aid in scheduling the activities (tasks) needed to complete a project
The charts show when an activity should begin and when it should end along a timeline.
Gantt charts can also reflect the resources assigned to each task and by what percent allocation.
Gantt charts can also be used to track the achievement of milestones or significant accomplishments for the project, such as the end of a project phase or completion of a key deliverable.
Progress of the entire project can be read from the Gantt chart to determine whether the project is behind, ahead, or on schedule compared to the baseline project plan
The advantage of using a Gantt chart is that it helps you monitor your project’s progress and set priorities.
The disadvantage of the Gantt chart is that it does not show the dependency of tasks to each other, and it does not show which tasks are ‘critical’ to finishing the project on time.
