“…Requirements define what stakeholders such as users, customers, suppliers, developers, and manufacturers need and how each is satisfied (Hull et al 2005). Thus, one of the initial steps in the design process is to correctly identify and specify the system's requirements because their use and proper maintenance is crucial to the success and efficiency to any design project (Chen et al 2007).…”

“…Requirement changes introduce negative consequences such as increased complexity (Chen andZeng 2006, Palmer et al 2010), potential data loss , and cost and time wasted . A designer could save time and money if it were possible to make a quick, yet accurate, assessment about the overall effects of a design or requirement change before committing to implementing a change (Stahovich and Ollinger 2001).…”

Abstract:For several decades, a wide-spread consensus concerning the enormous importance of an in-depth clarification of the specifications of a product has been observed. A weak clarification of specifications is repeatedly listed as a main cause for the failure of product development projects. Requirements, which can be defined as the purpose, goals, constraints, and criteria associated with a product development project, play a central role in the clarification of specifications. The collection of activities which ensure that requirements are identified, documented, maintained, communicated, and traced throughout the life cycle of a system, product, or service can be referred to as "requirements engineering". These activities can be supported by a collection and combination of strategies, methods, and tools which are appropriate for the clarification of specifications. Numerous publications describe the strategy and the components of requirements management. Furthermore, recent research investigates its industrial application. Simultaneously, promising developments of graph-based design languages for a holistic digital representation of the product life cycle are presented. Current developments realize graph-based languages by the diagrams of the Unified Modelling Language (UML), and allow the automatic generation and evaluation of multiple product variants. The research presented in this paper seeks to present a method in order to combine the advantages of a conscious requirements management process and graph-based design languages. Consequently, the main objective of this paper is the investigation of a model-based integration of requirements in a product development process by means of graph-based design languages. The research method is based on an in-depth analysis of an exemplary industrial product development, a gear system for so-called "Electrical Multiple Units" (EMU). Important requirements were abstracted from a gear system specification list and were analyzed in detail. As a second basis, the research method uses a conscious expansion of graph-based design languages towards their applicability for requirements management. This expansion allows the handling of requirements through a graph-based design language model. The first two results of the presented research consist of a model of the gear system and a detailed model of requirements, both modelled in a graph-based design language. Further results are generated by a combination of the two models into one holistic model.

“…Zeng and Chen [8][9][10][11][12] propose some concepts, which we have adapted for our model, such as defining a product in terms of the elements of its environment, the use of requirement categories based on the product's life stages, and mapping natural language to a standardized representation. However, they do not provide an implementation strategy for actually authoring a PDS.…”
