GanntProject is named after the industrial engineer who decided to come up with an easier way to plan and forecast projects.
That's the idea behind GanttProject which allows you to break down your project into a tree of tasks and assign human resources that have to work on each one. Most importantly, you can easily establish dependencies between tasks such as: 'this task can't start until this one is finished'. GanttProject then renders your project using two charts, which display how each project is connected.
You may print your charts, generate PDF and HTML reports or exchange data with Microsoft Project and spreadsheet applications. The big plus with GanttProject is that it's extremely easy to use - most project management apps can take some getting used to but GanttProject has you up and running within a few minutes and there's plenty of online help and user forums if you get stuck.
GanntProject is an excellent tool for those who need to plan projects without having to worry about learning a big project planning application.
