From the reviews:
“To develop a meaningful measurement system, the authors augmented the goal, question, metric (GQM) method. ... The result is a multi-level view of measurement that is linked by the defined enterprise service to its reusable software objects and respective business processes. This cohesive SOA measurement approach ... would be useful to any organization. The authors provide practical guidance, multiple diagrams that capture the relationships of artifacts and concepts, and a brief example for clarity.” (Nancy Eickelmann, ACM Computing Reviews, August, 2010)
