An artefact that is produced, is quantifiable, and can be either an end item in itself or a component item. Additional words for products are material and goods. Contrast with result. See also deliverable. Any input to or output from a project. PRINCE2 distinguishes between management products (which are produced as part of the management or quality processes of the project) and specialist products (which are those products that make up the final deliverable). A product may itself be a collection of other products.
