Marketing operations is a framework for how marketing projects and campaigns are delivered.  A marketing operation will include project management which could be Agile or Waterfall, processes & workflow for campaign delivery, marketing automation, data management, and reporting.  Often marketing operations are limited in scope to marketing automation tools or Martech (marketing technology) management.  However, the operations of marketing reach across brand management, sales and marketing alignment, creative/campaign production, and into technology implementation and support.
