Strategies for Smart Service Prototypes - Implications for the Requirements Elicitation in the Early Development Stages

摘要

The purpose of this paper is to investigate how can prototypes contribute to the requirements elicitation for smart services in the early development stages. Smart services are delivered to or via intelligent objects and are characterized by context awareness, connectivity, and data-driven value creation. Smart services and prototyping are emerging topics in requirements elicitation and pose challenges to existing approaches. This article creates a fundamental understanding for the requirements elicitation by characterizing smart services in a layer model that illustrates the structure, processes, and interaction of the networked components. Based on this, the strategies outline ways how prototypes for smart services can be composed in a result-oriented way and applied in requirements elicitation. The models are based on the results of a comprehensive literature review and demonstrate their relevance using case studies from the mobility sector.
