Course Objectives
This training course is designed for advanced UML system analysts and developers who want to produce a system requirement model using use cases and object oriented analysis model released from the implementation of system requirements.

The rigorous approach in writing the use case ensures that the results satisfy both technical and non technical stakeholders. The models based on UML 2.1 is sufficiently detailed to form the basis for the design of a system that can use a variety of different architectures. The course discusses the advantages of this approach used for the estimation, traceability, development of testing and project management. Each technique is treated with a level of detail that can be used in the context of an actual project.

At the end of the course
Participants will learn the following skills:
  • The basics and the details of UML v2.1 and Object Oriented methodology.
  • How to create a summary view of the functional requirements by using actors and use cases with use case diagrams.
  • How to make effective description of the system based on use cases that will be satisfactory for both technical and non-technical stakeholders.
  • What are they and what are not actors and use cases.

Training method
Theoretical and practical, or course elements will alternate theoretical illustration of specific cases and demonstration of the UML methodology. Delivery will be based on practical-exercises, for which the exercises will be balanced on the basis of the relevance of the topics covered.
