The document discusses service-oriented analysis which is the process of determining how business automation requirements can be represented through service-orientation. The objectives are to identify what services need to be built, what logic should be encapsulated by each service, and define preliminary service boundaries. The analysis process involves defining business requirements, identifying existing systems, and modeling candidate services to group them into logical contexts.

1. SERVICE-ORIENTED
ANALYSIS

2. SERVICE-ORIENTED ANALYSIS
The processs of determining how
business automation requirements can be
represented through service-orientation is
the domain of the service-oriented analysis.

3. Objectives of service-oriented
analysis
The primary questions addressed during this
phase are:
-what services need to be built?
-what logic should be encapsulated by
each service?

4. The overall goals of performing a service-oriented
analysis are as follows:
• Define a preliminary set of service operation
candidates.
•Group service operation candidates into logical
contexts.
•Define preliminary service boundaries.
•Identify encapsulated logic with reuse potential.
•Define any known preliminary composition models.
•Ensure that the context of encapsulated logic is
appropriate for its intented use.

5. The service-oriented analysis process
-The service-oriented analysis process is a
sub-process of the overall SOA delivery life-cycle.
-Service-oriented analysis can be applied at
different levels, depending on on which of the SOA
delivery strategies are used to produce services.
-The chosen strategy will determine the
layer of abstraction.
-Each layer has different modeling
requirements.

6. What outstanding work is needed to
establish the required business model(s) and
ontology?
What modeling tools will be used to carry
out the analysis?
Will the analysis be part of an SOA
transition plan?
The questions that should be answered prior to
proceeding with the service-oriented analysis
include:

8. Step 1: Define business automation requirements
Requirements are collected for analysis process.
Creation of services in support of service-oriented solution.
High-level automation process can be defined.
Step 2: Identify existing automation systems
SOA will not determine how exactly web service will encapsulate
Web services relate to existing system are iorned out
Step 3: Model candidate services
Introduces the concept of service modeling
Candidates are identified & grouped into into logic context
