Situation: about 85 projects in a portfolio. As PMO, want a simple tool for project managers to submit change requests for major changes to their projects, principally to request a change to end date and provide a rationale for why the date needs to change. Ideally, a link from the project plan that allows a form pop-up to include basics (what is changing and why), with an ability at the portfolio level to see across all projects and keep track of the change requests coming in. Allow review of those by leadership and approval to be documented and update the portfolio.
