KAOS (software development)

KAOS, is a goal-oriented software requirements capturing approach in requirements engineering. It is a specific Goal modeling method; another is i*. It allows for requirements to be calculated from goal diagrams.[http://www.cs.utoronto.ca/~alexei/pub/Lapouchnian-Depth.pdf Goal-Oriented Requirements Engineering: An Overview of the Current Research]. KAOS stands for Knowledge Acquisition in automated specificationA. Dardenne, A. van Lamsweerde and S. Fickas. Goal-Directed Requirements Acquisition.

The University of Oregon and the University of Louvain (Belgium) designed the KAOS methodology in 1990 by Axel van Lamsweerde and others.[http://www.objectiver.com/fileadmin/download/documents/KaosTutorial.pdf A KAOS Tutorial]. It is taught worldwide at the university levelList of universities teaching KAOS include Michigan State ([http://www.cse.msu.edu/~cse870/Lectures/Notes/02c-kaos-goal-modeling-bhc-v3-notes.pdf lectures]), Pace ([http://csis.pace.edu/~marchese/CS775/Lectures/775L6b.ppt lectures]), Louvain ([https://www.cs.scranton.edu/~mccloske/courses/se507/vanLams_kaos_presentation.pdf lectures]), Coimbra and others. for capturing software requirements.
