This book constitutes the thoroughly refereed postproceedings of the First International Workshop on Rapid Integration of Software Engineering Techniques, RISE 2004, held in Luxembourg-Kirchberg, Luxembourg in November 2004.

The 12 revised full papers presented together with an invited paper went through two rounds of reviewing and improvement and were selected from 28 initial submissions. Among the topics addressed are software architecture, software process, component-driven design, dynamic service verification, model checking, model-based testing, exception handling, metamodeling, UML, state machines, and model-centric development.
