Users requirements elicitation in the Lyee Software factory

The paper deals with the modelling of user requirements in the Lyee-Sorbonne project and their relationship with Lyee software requirements. The Lyee-Sorbonne project aims to reduce the software development cycle to two explicit steps, requirements engineering and code generation by coupling the code generation features of LyeeALL with an interface to capture user requirements. The paper uses a meta modelling approach to formally define the concepts underlying a user requirements specification, their properties and their relationships. It presents the meta model and illustrates its use through a small example. It also outlines the next steps of the project.
