ISEB Systems Modelling Techniques with UML

Course Features

This course provides participants with a framework and a proven set of techniques to use when specifying IT systems. It has been created using UML, the Unified Modeling Language, which has become a de-facto standard for systems specification. During the course, theoretical concepts are introduced and are then reinforced through practical exercises where participants can apply the skills and techniques of analysis through a series of realistic exercises. Participants thus acquire knowledge and the ability to apply UML effectively in project situations.

This programme can be combined with Systems Development Essentials to provide a complete course in basic systems analysis.

A comprehensive course manual, containing detailed information about the UML techniques and their application, as well as providing references for further reading, is supplied as part of the course.

ISEB qualification

This course prepares participants to sit a one-hour, open book, examination leading to the certificate in Systems Modelling Techniques offered by the Information Systems Examinations Board (ISEB). This certificate is a core certificate in the ISEB diploma in Systems Development and is also an optional certificate in the ISEB diploma in Business Analysis.
