Abstract

Manageability directly influences a system's reliability, availability, security, and safety, thus being a key ingredient of system dependability. Alas, we do not have today a good way to measure manageability or reason quantitatively about it, and this is a major hindrance in improving systems' ease of management. In this paper, we propose a manageability metric that aims to be objective, intuitive, and broadly applicable. We hope such a metric will help software developersmake the right design tradeoffs and will also foster fair competition on the basis of manageability. We also offer preliminary thoughts on incorporating this metric into a benchmark.
