Imagine you have been appointed the project manager for the National Aeronautics and Space Administration (NASA), U.S.A to work on developing and launching a rocket and crew vessel that will get people on Mars for vacation. Using a PMLC model, identify and prioritize the main activities you would consider for this complex project and outline an implementation plan. What would be some of the complexities you believe you could face with this project? How could you use the Requirements Breakdown Structure (RBS) to help you handle uncertainties that you might face and to ensure successful delivery of this projects?
