EXHIBIT 7.6 GRANULARITY ANALYSIS ON A COMPOSITE SERVICE STRUCTURE FORMATION
from early stages of the life cycle and throughout management time in production environments.
Thus, the granularity analysis should facilitate a service evolution strategy to plan granularity
development during a succession of projects. To accomplish this task, partition the granularity
matrix into time sections, as depicted in Exhibit 7.7. A one-to-five-year projection reveals an organizational
development strategy and introduces new services and abstractions. As time evolves,
practitioners will be able to continuously adjust the granularity matrix to reflect organizational
business requirements and new technology priorities.
