Lessons Learned Manage your cost! Funding and design should be simultaneously managed. Mitigating high cost. Switching material sizes. Teamwork! - Communicate and divide the project into portions. - Make sure everyone knows everyone else's job. Organization Maintain to do lists between team members. Meet deadlines placed on each other.
