Scenario Planning Options for the PMO / Ask the Expert

The question gets answered – We are looking for a web-based simple scenario planning/capacity tool where we can input basic project data (i.e. expected size, effort and duration) and then model this against our capacity. We are not looking for a full PPM tool, as we already have a tool in place for the project reporting, RAID, etc.; it’s more about at a high level planning our portfolio roadmap and having the ability to complete simple ‘what-if’ scenarios. This would be a tool used by the PMO rather than project managers.
