Gantt charts are very important to the project because it highlights the milestones for the project. The critical path is crucial because it ensures the project is running on time and there will be no issues when moving onto the next milestone. The critical path makes sure there will be no deviations. When deadlines are missed, it sets the project back but the team must find a way to make up for the missed milestone. But when the project manager is first creating the Gantt chart, he/she must make sure there is enough time to finish the task within a certain time frame. When given not enough time, it causes the milestones to be missed or the project members to work overtime. The project manager should always leave about 2-3 days buffer for each milestone to ensure it being reached.
