So your organization decided to get a new Content Management System (CMS), either replacing an existing CMS or as your first CMS. A strong organizational temptation will probably be to treat implementing the CMS for your institution as a project rather than as an internal product. But in addition to project management, you'll need product management. It's unfortunate that project, product, and program management all have the abbreviation of PM, and that may contribute to the confusion between these terms.
