Abstract

Scenario-based specifications offer an intuitive and visualway of describing design requirements of distributedsoftware systems. For the communication paradigm basedon messages, message sequence charts (MSC) offer a standardizedand formal notation amenable to formal analysis.In this paper, we define shared variables interaction diagrams(SVID) as the counterpart of MSCs when processescommunicate via shared variables. After formally definingSVIDs, we develop an intuitive as well as formal definitionof refinement for SVIDs. This notion provides a basis forsystematically adding details to SVID requirements.
