In this milestone, you will develop a resource management plan and update your project using MS Project software. When building a project plan, project managers use the resources an organization makes available to complete the work necessary to deliver the project. When a project manager builds a project plan, work packages are created that define the specific work activities that need to be completed. It is essential that a project manager understand what work needs to be completed so he or she can determine what resources $($people$,$ materials, knowledge, money$)$ are needed, for how long $($duration$),$ and when these resources are needed $($schedule$).$ Some of this will be known and some unknown.
