Using Microsoft Excel, Project, or another project management tool of your choiceand approved by your instructor, develop two milestone-level project plans: one using the waterfall and one using Agile SDLC. The milestones should demonstrate a clear understanding of the inputs and outputs for each phase of a project, based upon the SDLC applied. At minimum, there should be a clear milestone at the end of each project phase, and potentially milestones within phases where applicable. Ensure that each project plan incorporates comprehensive SDLC phases based on each SDLC type.
