Elevator manufacturers such as Schindler and OTIS have been successfully pursuing the path of servitization for many years. Triggered by increasing margin erosion in the new installations business, manufacturers are forced to offer profitable service concepts alongside the traditional product business. Based on in-depth product and application knowledge, a service business can be developed that generates continuous and above-average profitable revenues. In other industries, this realization is reinforced by the possibility of tying consumables ever more closely to one's own product, to the point of technical dependency.
