Tamara is leading her team in planning for her project. She completed the work breakdown structure (WBS) as a detailed expression of project scope. She then broke each work package in the WBS down to the activities necessary to deliver each work package, sequenced the activities, estimated resources and durations, and developed the schedule baseline. She then estimated the cost of resources associated with each activity, spread the cost of those resources over time using the project schedule, accumulated those costs over time, and graphed them with costs on the vertical axis and time on the horizontal axis. She has just created: Group of answer choices the cost framework the project management plan the performance measurement baseline the project foundation
