Service-Oriented Analysis Endeavor 5
This service verification process must also confirm if the service design and architecture model
meets business requirements or technical specifications. In other words, the major queries that typi-
cally should be asked during this evaluation activity are related to a service’s capabilities to satisfy
its corresponding consumers’ necessities: “Can a service’s offerings alleviate the identified business
challenges?” “Does the service provide a technological solution?” “Does the service design model
adhere to organizational best practices?”
Authentication Analysis Iteration: Analyze before and during Service Operations. To ensure
flawless execution of a service in a production environment, a service should be certified. This is an-
other analysis effort that should take place before a service is ferried out to production and assumes
the responsibilities that it was designated. Thus the authentication process should be broadened
to include the inspection of internal service functionality as well as external vital aspects of ser-
vice integration, collaboration, interoperability, and configuration. Furthermore, the certification of
a service should not conclude with its deployment effort to a production environment. This process
must persist to meet the challenges that a service might face in production, during which volatile
market conditions, changes to the business mission, technological discontinuity, and disruptions to
transaction processing might occur.
SERVICE ANALYSIS APPROACH. Finally, when pursuing the service analysis process to assist with
carving out a solution, adhere to a methodical approach that not only offers direction and milestones
to attain, but also underlines the importance of achieving predefined goals. The quest for feasible
services that can provide a satisfying remedy to an organizational concern then must be driven by an
analysis road map that is lucid and unambiguous to analysts, architects, developers, modelers, and
managers. The starting point, midpoints, and end point of the service inspection endeavor must be
crystallized by employing repeatable patterns. These are guiding templates that are accepted by the
governance body of an organization whose duties include carving out best practices and standards
to streamline the analysis process.
In the sections that follow we introduce a general template for pursuing a service-oriented
analysis venture.

This is a guiding road map that identifies the four major perspectives of service
inspection process that covers vital aspects of internal and external service design and architecture.
Exhibit 1.2 illustrates this concept. Note that in addition to the four recommended analysis orien-
tations, the practitioner should adhere to the overarching organizational practices that help shape a
service-oriented analysis venture:
1. Look in the Box.
2. Look out of the Box.
3. Look above the Box.
4. Look below the Box.
Look in the Box. The solution that we are commissioned to propose is obviously executed by
internal service operations. This service internal functionality embodies business and/or technical
processes and is the manifestation of business requirements and technical specifications. Therefore,
the practitioner should look in the “solution box” to analyze the service’s internal affairs and the
contribution of its capabilities to rectifying an organizational problem. While analyzing a service’s
internal construct, service interfaces, communication mechanisms, and binding contracts with corre-
sponding consumers are also vital considerations that must be examined. Remember, these internal
service examinations that should take place during the inception, assessment, verification, and au-
thentication service-oriented analysis iterations should persist during a service’s life cycle to perfect
its operations, boost its reusability rates, and increase its performance abilities.
