Master Data Management (MDM) continues to scale as explored in the post about how MDM inflates.
One inflating trend can be named Extended MDM, which is about taking other data domains than the traditional customer, supplier, and product domains under the MDM umbrella and thus creating a governed data hub.
Which entities that will be is industry specific. Examples from retail are warehouses, stores, and the equipment within those. Examples from pharma are own and affiliated plants, hospitals and other served medical facilities. Examples from manufacturing are plants, warehouses as well as the products, equipment and facilities where the produced products are used within.
