Architecture is a blueprint of system design and implementation, and whether it can guide practice correctly largely depends on the architecture verification and evaluation. Executable architecture provides a new way to validate and evaluate the architecture. In order to make all architecture products into a whole executive entity, this paper puts forward a new concept—execution rules description. Execution rules describe the execution, call and data flow relationship between architecture products, and thus provide special background information for the architecture execution. Through standard dynamic executive model interfaces, execution rules can call the models' executable engines, and then attain the aim to run the architecture on the whole. That architecture can run successfully, providing justification for architecture verification, and its executive result also provides justification for architecture evaluation.
