In todays business environment, change must be seen not as an exception but as the normal state of affairs. With its Darwin Architecture, HP addresses business agility, defined as the ability of one enterprise to respond to and anticipate business changes with speed and flexibility while meeting cost, quality of service and risk management objectives. One of the requirements that agility imposes on an enterprise is that their business groups and IT (Information Technology) groups must come together to create an adaptive enterprise in which business needs drive IT response, and business and IT changes are synchronized in real time. When projected onto the space of IT management, this requirement is translated into the need of managing IT in light of the business objectives of an enterprise. We introduce Management by Contract (MbC) as a paradigm to address this need. In this work we present the basic ideas of Management by Contract and we give a motivating scenario describing a hypothetical company that hosts IT infrastructure. We then describe the architecture of our prototype system, report on some experimental results and sketch the future directions of our research.
