In todays turbulent environment, manufacturing companies are forced to efficiently change or develop production systems that are robust and dynamic enough to handle changing production situations during its entire life-cycle. To achieve such a production system requires a structured development process that should be carried out simultaneously to the product development process and considers the companys product portfolio. Within a structured development process, the requirements specification of the proposed system is vital since it will guide the design process and the evaluation of the system on a conceptual as well as a detailed level. The aim of this paper is to address the requirement specification process that covers all aspects of the production system to be designed. This paper argues for the need of a holistic view in the requirement specification process of production systems. A holistic view of the overall process will facilitate to manage the various demands and categories important to deal with in the specification of requirements. Based on the holistic view it will be possible to identify the gates and stakeholders of the process itself, but also the substantial content of this process map.
