Software maintainability largely depends on architecture design. The maintainability metrics in architecture phase can offer a basis for the choice of many architecture design projects, and can identify the best architecture design. In order to measure software architecture maintainability, firstly, six kind symbol connectors and their connection semantics are defined according to the relationship between components, and software architecture is described based on symbol connector; Then the ripple-effect of architecture change based on symbol connectors are analyzed, and software architecture maintainability is obtained through computing propagated numbers of connectors; Lastly, by applying this method to a case, the feasibility and effectiveness of the method is fully validated.
