Business Systems
Analysis
for Object Oriented Projects with UML
3 Day Course Description
The key to effective business analysis is to provide
specification of “what” functionality a software system
will provide its users, rather than “how” the software will
be designed. But too often traditional business analysis
produces artifacts and specifications that do not align
with the concepts of object-oriented design and development.
This course focuses on how business analysts and business
systems analysts can provide object-oriented developers
with concise specifications of the problem domain within
which a software solution will be constructed. Students
will learn the power of the Unified Modeling Language version
2 (UML 2) for expressing business concepts and project goals
using object-oriented models, to prepare for either in-house,
or out-sourced, technical design and implementation. Extensive
hands-on exercises using two complete, and parallel, case
studies assure that students see how a concept is modeled,
and then have the opportunity to immediately apply and test
their understanding.
Audience
Business analysts and project managers who need
a common, practical technique for constructing business
analysis specifications of object-oriented systems.
Prerequisites
Experience in analysis is desirable, but not mandatory.
