Microsoft EPM Capacity Planning
Selecting project portfolios based on ROI or value optimization only does not guarantee that the organization has the right mix of resources or available resources to actually deliver projects as planned.
Availability and utilization of resources has a direct effect on how and when work is completed. A common problem that many organizations face during an annual planning cycle is that prospective projects are front-loaded on the planning horizon. This can potentially result in over-allocation of resources in the first half of the year and underutilization of resources in the second half of the year. Project Server 2010 includes a capacity planning feature for conducting resource constraint analysis that works in conjunction with cost constraint analysis to connect value optimization with resource utilization.
