This book constitutes the refereed proceedings of the 6th International Conference on Integrated Formal Methods, IFM 2007, held in Oxford, UK. It addresses all aspects of formal methods integration, including of a process of analysis or design application of formal methods to analysis or design, extension of one method based upon the inclusion of ideas or concepts from others, and semantic integration or practical application.
