Project Plan Information
Project Plan as of today The project plan as of today should show a skeleton of the project. It will be changed throughout the course of the semester Should mainly show team structure and the main milestones that are set as of right now. Schedule we have provided to you
Project Plan later on As more information is discovered about the system the project plan will change. Think of it in the spiral model way As you discover the modules you are developing they should be placed in the milestones area Tools you may need will be updated
