BAU – There is often confusion about work that fits under the Business As Usual banner and what falls into the project space. Business As Usual is the work undertaken as part of standard daily business operations. Project work differs in that it has a defined start and finish. Projects also have a separate budget.
PMO – The PMO is your Project Management Office. It has been set up as a place for support for you as a Project Manager. A PMO will usually play the role of governance adviser for your project also, checking that you are completing the right things at the right time. That is why it is imperative that your PMO contains staff with a project management background.
