Abstract. When there are insufficient inputs for a product-level approach to requirements elicitation, a process-level perspective is an alternative way for achieving the intended base requirements. We define a V+V process approach that supports the creation of the intended requirements, beginning in a process-level perspective and evolving to a product-level perspective trough successive models derivation with the purpose of creating context for the implementation teams. The requirements are expressed through models, namely logical architectural models and stereotyped sequence diagrams. Those models alongside with the entire approach are validated using the architecture validation method ARID.

Part 6: Enterprise Modelling CasesInternational audienceAt the analysis phase of an enterprise information system development, the alignment between the process level requirements (information systems) with the product level requirements (software system) may not be properly achieved. Modeling the processes for the enterprise’s business is often insufficient for implementation teams, and implementation requirements are often misaligned with business and stakeholder needs. In this paper, we demonstrate, though a real industrial case, how transition steps and rules are used to assure that process- and product-level requirements are aligned, within an approach that supports the creation of the intended requirements. The input for the transition steps is an information system logical architecture, and the output is a product-level (software) use case model
