The objective of the paper is to further understand value creation for the after-sales services. We present the case of the creation of a new business for the after-sales services for the entrance into a new market. The new business is created by two gurus in the aerospace industry. A typology of guidelines is derived, based on organizational and strategic perspectives, for the after-sales services value creation and the guidelines for the creation of a new business as well as for the entrance of into a new market are presented.展开更多
