This paper presents a distributed change management framework that enables the assessment and minimization of service-delivery disruptions. The framework handles both external change requests, like software upgrades, and changes to mitigate internal events, such as faults. Objective-specific modules assess the impact of change operations on service delivery through their impact on the business values of the corresponding performance or dependability objectives. A centralized component then schedules the changes in order to maximize the business value across all service objectives over a long timehorizon. We evaluate this framework using a realistic change-management scenario.
