In this paper common characteristics of XXL-products are shown and a potential basis for the definition of XXL-products is derived. The proposed definition is based upon the hypothesis that man encounters his technical, organizational and economic limits with the methods and tools available at the time of observation, in the context of the creation of a XXL-product. The proposed definition will provide a clear distinction between conventional products and XXL-products. This enables precise discussions and the development of product-spanning solutions to overcome common challenges of XXL-products.
