This volume contains the refereed proceedings of the ?rst edition of three wo- shops colocated with the International Conference on Formal Techniques for Networked and Distributed Systems (FORTE). The workshops took place in Toledo (Spain) on the 1st and 2nd of October of 2004, and they dealt with d- ferent topics related to the application of formal methods. The names of the workshops were the following: TheFormEMC: 1st International Workshop on Theory Building and Formal Methods in Electronic/Mobile Commerce EPEW: 1st European Performance Engineering Workshop ITM: 1st International Workshop...

Software validation is one of the most cost-intensive tasks in modern software production processes. The objective of FATES/RV 2006 was to bring sci- tists from both academia and industry together to discuss formal approaches to test and analyze programs and monitor and guide their executions. Formal approaches to test may cover techniques from areas like theorem proving, model checking, constraint resolution, static program analysis, abstract interpretation, Markov chains, and various others. Formal approaches to runtime veri?cation use formal techniques to improve traditional ad-hoc...
