No I don't think additional metrics are useful or accurate. Some stories require minimal code changes, but lots of time doing other things such as testing, talking to customers, gathering requirements, going to meetings with stakeholders, analyzing the problem, etc etc. Most of these tasks cannot be easily quantified or reduced to a simple metric.

Its still useful to represent these things as stories, because a story is really a piece of functionality from the customer's PoV. They don't care if it takes 1 line of code or 1000. But a good team will realize that the assigned story points are not simply a function of the code size, there's lots of other pieces of work that need to be done. The types of work are so varied and different that finding a uniform, quantitative way to measure them is pretty hopeless. That's why story points are used -- They are a qualitative estimate based on the team's experience with similar features in the past and what those cost in terms of story points.

I especially agree with the second paragraph. – Hexxagonal Mar 29 '12 at 14:01
In the end, what matters is if the project delivered what the customer wanted and that it was done on schedule, the ultimate qualitative metric. Of course, managers need quantitative measurements to justify hiring/firing, raises and such. – jfrankcarr Mar 29 '12 at 14:16
Thanks for your reply. Velocity indeed seems to be the best, but is it the only way? – Asahi Apr 1 '12 at 10:57
