I have yet to work in industry, but I do have experience in creating gantt charts in my capstone class in high school and during my undergraduate years in BME. I feel that sometimes the timelines are always off or not effectively predicted. For the next time, I have learned to meet with others to discuss how much time is needed for each event that needs to be completed before setting the date. Certain resources are needed in order to finish the project and gathering project material is also a necessary goal and should be put on the gantt chart. It is also important, like hc255 said above, to have weekly or biweekly meetings with the whole group in order to make sure the deadlines are being met. Although group gantt charts are essential, it is also important to make self gantt charts in order to make sure that your duties are being met and being accomplished on time. I believe that creating and using a gantt chart can make a difference in when a product or project is successful or not.
