An Original Design Manufacturer (ODM) is a company which manufactures a product which ultimately will be branded by another firm for sale. Such companies allow the brand firm to produce (either as a supplement or solely) without having to engage in the organization or running of a factory. A primary attribute of this business model is that the ODM owns and/or designs in-house the products that are branded by the buying firm. This is in contrast to a Contract manufacturer or CM.

The interface of the original object needs to be maintained by the decorator.
