Entwicklung hybrider Produkte — Gestaltung materieller und immaterieller Leistungsbündel

Requirements Engineering for Product Service Systems

“…RE has the goal of systematically determining the requirements to a product correctly and completely (Byrd et al 1992). In this way, RE creates the basis for all following development steps (Spath and Demuß 2003). As errors in the requirements specifications often cause project failures and cost-intensive changes at a later point in time (Pohl 2007), RE is seen as a crucial factor in the development process.…”

“…Customer requirements definition: In this phase, the requirements to the PSS are elicited and analyzed (Spath and Demuß 2003). Particularly, the customer needs are in the foreground of requirements elicitation, since they serve as a basis for the subsequent implementation (Sawhney 2006).…”

“…For a successful implementation of both phases, the provider of the solution must know the prerequisites given by the customer. Due to these facts, an integrated development of all PSS components is essential (Spath and Demuß 2003). If subsequent changes in the requirements occur, the task of RE in that case is to update the current specifications and to keep them up-to-date.…”

“…In the development process of PSS, the hardware, software, and service components are developed in parallel, and coordinated by the involved disciplines (Spath and Demuß 2003). Aurich et al (2007) propose a process model for the life cycle management of PSS.…”

“…According to Spath and Demuß's (2003) "hybrid product development" approach, the development of PSS exclusively focuses on the single elements of the solution. Thereby, the requirements are elicited, analyzed, and used for the derivation of the product structures regarding material and immaterial components in the form of a requirements model that has to be updated during the entire development.…”
