Assume you worked for a small company developing Web-based software. Further assume that your company presently makes no use of software metrics. If you were allowed to identify and collect data for only one metric (it can be a complex metric involving many measures), which metric would you choose and how would you use the information you obtained. (Although you are only allowed to identify one metric, assume that you are free to collect data at any time and as often as you like during the development process.)
