Gantt Chart

A Gantt chart is a project management tool which illustrates a project schedule
Gantt chart keeps track of task dependencies and displays the progress of theproject.
A Gantt chartillustrates:
- The tasks requiredfor the currentproject
- How long you expectthe projectto take
- Dependencies: in other words, any tasks that must be completed beforeothers can be started
Gantt charts havetwo types of dependency:
- Tasks that depend on the output of other tasks.
- Tasks that depend on people who are also working on other tasks

Break your project into phases and each phase down into tasks
Assign each task to a person or small team
Set an estimated amount of time for the task
Note which tasks are dependent on others
For each tasks; specify who’ll be doing the task; star and end dates; any dependencies on previous tasks
List the days or weeks of the project across the top of the chart
Block out the time period that each task is due to take up
Check that dependent tasks don’t overlap

You may have overlapping tasks as long as they don't need the same resources or people or need input from each other’s output.
You'll need to keep track of your Gantt chart up to date. Your team will rarely meet the target on time. They could complete tasks either early or late.
There will be many dependencies on certain tasks. Particularly later on in a project.
