Combining Domain-Driven Approach with Requirement Assets for Networked Software Requirements Elicitation

Networked software (NS) is a service-oriented software application that is accessed via human-network interaction equipments. Owing to the characteristics(such as uncertainty, incompleteness, and evolution) of NS requirements, the requirements engineering face challenges in requirements elicitation. This paper proposes a requirements elicitation approach for networked software that builds a bridge over the gap between user requirements for understanding and system requirements for designing. A new language, called SORL, is proposed to describe user requirements with functional and non-functional properties for NS. The proposed approach is capable to transform user requirements with SORL into domain-SORL for reusing domain requirement assets with deep semantic supports. The actual application shows that the approach which discussed in this essay can improve the flexibility of requirements elicitation in networked environment and continuously evolve with lower cost.
