The benefits of Service Oriented Architectures for business are well recognised, however defining the correct composition of services for a particular business process can be very challenging. In this paper we present the ALIVE approach to composing Web services to meet business goals. Our approach involves the use of agents to enact plans of actions which achieve organisational goals, where each action specifies what should be achieved as opposed to which service to use. When enacting an action, agents use a matchmaking process to determine services that can be used to achieve the desired effects, intelligently handling any errors that may occur. The action plans are based on an organisation model, allowing the set of actions available to the plan synthesis mechanism to be tailored to the goal being targeted at that specific time, further reducing the planning search space.
