You can find free templates for virtually anything these days, and that can actually amount to some confusion. What is the difference between project management templates and PMO templates? Or do they just overlap somehow? A post at PM Majik attempts to clarify the situation. It says, in essence, that project teams use project templates to help them manage or report on their project. By comparison, PMOs use PMO templates to record data from various projects or programs, etc. So PMO templates attempt to collect data on a wider scale.
For a list of different types of templates you can expect to see used in projects and PMOs respectively, you can view the original post here: https://www.pmmajik.com/difference-project-pmo-templates/
