Loraine Lawson, Dave Linthicum, and Dan Foody picked up on my recent post on measuring SOA, and provided additional insights to the whole question of service-oriented metrics.
I like how Loraine described the post as the kick-off to the quarterly "how to calculate SOA's ROI" discussion. Loraine also did a great job of distilling many of thoughts Dave, Dan and Red Hat's Mark Little provided (plus additional metrics from Leo Shuster) into 12 succinct points.
These form a great foundation for establishing core SOA metrics:

These form a great foundation for establishing core SOA metrics:
- Return on investment (ROI) per service.
- Revenue per service.
- Service growth rate/reuse,or Number of New Services Generated and Used as a Percentage of Total Services.
- Business agility or Mean Time to Service Development.
- Mean Time to Service Change.
- Reliability or Service availability.
- Service Vitality Index.
- Efficiencies associated with service reuse.
- Integration time savings.
- Related opportunity costs.
- Cost savings/avoidance.
- Reduction in project and maintenance costs.
