Tools available for measuring t impact of change of a system through its ar use structural metrics. These metrics t dependencies among the different elements of they fail to capture the semantics of transformation necessary to control the com making changes. To highlight such limita presents a study where we applied a repres metric, called 'propagation cost', to archety transformations known to affect system mo rearchitecting a tightly coupled system to a la observe that in its original form the propagati not provide consistent indications of ar Enhancing this metric based on the semantics pattern and tactics used in the tran improvements. Our results demonstrate that t detect modifiability properties that are not propagation cost metric. Keywords—software architecture; modifia cost; stability; change propagation; dependency
