I especially like and use the system that Mary Poppendieck recommends. This system is based on three holistic measurements that must be taken as a package (so no, I'm not going to provide 3 answers):
- Cycle time
- From product concept to first release or
- From feature request to feature deployment or
- From bug detection to resolution
- Business Case Realization (without this, everything else is irrelevant)
- P&L or
- ROI or
- Goal of investment
- Customer Satisfaction
I don't need more to know if we are in phase with the ultimate goal: providing value to users, and fast.
