A Product Family Approach to Graceful Degradation
Design of gracefully degrading systems, where functionality is gradually reduced in the face of faults, has traditionally been a very difficult and error prone task. General approaches to graceful degradation are typically limited to re-implementation of the system for a number of pre-designated fallback configurations. We describe an architecture-based approach to gracefully degrading systems based upon Product Family Architectures (PFAs) combined with automatic reconfiguration.
