Preface to the fourth international workshop on requirements, intentions, and goals in conceptual modeling (RIGiM 2012)

The use of intentional concepts, the notion of "goal" in particular, has been prominent in recent approaches to requirements engineering, producing a body of work focusing on Goal-Oriented Requirements Engineering (GORE). RIGiM (Requirements, Intentions, and Goals in Conceptual Modeling) aims to provide a forum for discussing the interplay between requirements engineering and conceptual modeling, and in particular, to investigate how goal- and intention-driven approaches help in conceptualising purposeful systems. What are the upcoming modelling challenges and issues in GORE? What are the unresolved open questions? What lessons are there to be learnt from industrial experiences?What empirical data are there to support the cost-benefit analysis when adopting GORE methods? Are there applications domains or types of project settings for which goals and intentional approaches are particularly suitable or not suitable? What degree of formalization, automation or interactivity is feasible and appropriate for what types of participants during requirements engineering?
