PMBOK mentions "Plan Resource Management is the process of defining how to estimate, acquire, manage, and use team and physical resources.", but it also use a tool RAM/RACI to "show the project resources assigned to each work package."(PMBOK page317). In Figure 9-4, PMBOK shows a RACI example which mentions team member names Ann/Ben/Carlos/Dina/Ed"
My question: Shouldn't resources be acquired and assigned after "estimate activity resources" and "acquire resource"? how can resource management plan assign resource?
