The key benefits of using Gantt charts:
Avoid confusion – all stakeholders will have a single document outlining the work to be done, who is responsible for the work, what additional resources are needed, and when the work is to start and stop.
Align task relationships – task dependencies are clearly defined and tasks that are expected to be completed in parallel are identified. Adherence to schedule is easy to maintain.
Team member communication is facilitated – responsible personnel are readily known, so issues either anticipated or real can be discussed.
Critical elements are apparent – team leaders are able to identify the aspects of development that are critical due to the number of dependencies defined.
Each team has already prepared a top level Gantt chart for their prototype development. With http://www.gantt.com/creating-gantt-charts.htm these benefits in mind, this chart must be completed in more detail. The team member responsible for each milestone must work with their sub-team (if any) to further break the milestone into clearly identified tasks/subtasks. It is expected that all team members will access the chart to add their details.
Assignment of resources is not necessary for these tasks, as you have already identified the responsible personnel. Start and stop date is not necessary unless dependencies need to be assigned.
This chart must be consistently available (latest version) on the teams’ websites. The instructor will monitor progress weekly. The completed chart is due at the end of Module 3.
Gantt.com provides excellent tutorials. You may also refer to the lecture available in the resource component of this module.
