The Business Process Execution Language (BPEL) has become the de-facto standard for the description of Web Service compositions. A variety of formal approaches to de- cide compatibility and consistency for BPEL processes has been presented. Nevertheless, these approaches suffer from high complexity and state explosion. Therefore we present a lean formalization of BPEL 2.0 based on the -calculus, that enables efficient reasoning. Due to our focus on be- havioral compatibility and consistency checking (and not on comprehensive formalization), we are able to reduce ef- fort needed for process verification. Besides the exemplary application of our approach, we also compare it to existing BPEL formalizations by means of complexity.
