This scenario-based RE approach allows to validate the requirements by means of simulation (i.e., the play-out algorithm originally conceived for LSCs) and to formally verify the requirements for consistency. However, these scenarios are specified on a plain structural basis that does not reflect the typical structure of component architectures, which are arranged in a hierarchical way and encompass ports, interfaces, and directed connectors.
