You can use the vRealize Operations Manager projects feature to plan for capacity upgrades or optimization in your virtual environment. You create a project to include upcoming changes that affect your capacity and is useful for capacity planning. A project has one or more scenarios where capacity or demand changes on a date in the future. You can visualize one or more projects in the visualization pane to forecast your capacity and demand. When a project is expected to happen, you can commit it, which reserves the capacity needed.
