Manageability can greatly influence the recurring costs and can increase the chances of a failure. Often a system that is hard to manage is described as fragile since the smallest change can have dire consequences on the system's functionality. |

However, in the absence of means to measure manageability and to quantify the various tradeoffs, it is difficult to get the design right. We proposed a manageability metric that combines management workloads and weightings based on real world studies with direct measurement of the number of steps involved in management tasks and their duration.
