Create conceptual decision trees for the given business requirements. This
structure should assist with the identification and categorization of conceptual services,
and later on, with the establishment of organizational taxonomy.
110 Ch. 5 Conceptual Service Identification
??? Conceptual services. The final outcome of the service conceptualization phase should
yield three types of conceptual services: atomic, composite, and cluster. These abstract
formations should not only propose preliminary remedies to organizational concerns, but
also be treated as a unit of analysis during the service-oriented discovery and analysis
phase (Chapters 6, 7, and 8).
??? Conceptual services portfolio and service taxonomy. These provide an organizational
taxonomy based on generalized discovered conceptual services. At the conclusion of this
process, the findings should be cataloged in the organization??™s software asset portfolio.
SUMMARY
Decision trees provide an efficient mechanism to identify new conceptual services and to categorize
abstractions and establish organizational service taxonomies.
There are four major methods that can assist with the establishment of service associations:
hierarchical, star, network, and circular. These mechanisms are used to enable future service
reusability, loose coupling implementations, functionality consolidation, efficient granularity, and
consumption and reusability assessment, as well as to set business priorities.
