The question addressed is: Is there need, in health care, for one consolidated science of production? For responding to this question, the classical science of production is reviewed and the current approaches to production and service in healthcare are analysed as for their evolution and current status. It is found that these current movements are not self-aware of the restrictions deriving from their backgrounds, and of the resultant partiality in their approaches. It is concluded that improvement of healthcare is slowed down by the fragmentation of the related disciplines; thus one consolidated science of production (of healthcare) is needed
