This paper discusses how evolution in software product lines can be supported using framed aspects: a combination of aspect-oriented programming and frame technology. Product line architectures and assets are subject to maintenance and evolution throughout their lifetime due to the emergence of new user requirements, new technologies, business rules and features. However, the evolution process can be compromised by inadequate mechanisms for expressing the required changes. It maybe possible to anticipate future evolutions and, therefore, prepare and design the architecture to accommodate this, but there will eventually come a time when a certain feature or scenario appears which could not have been foreseen in the early stages of development. We argue that frames and aspects when used in isolation cannot overcome these weaknesses effectively. However, they can be addressed by using the respective strengths of both technologies in combination. The amalgamation of framing and aspect-oriented techniques can help in the integration of new features and thus reduce the risk of architectural erosion.
