Course Description

At the end of this course you’ll not only have a good understanding of the models and methods used in system design, but you’ll also be able to apply them confidently to a multitude of project situations.

For that reason, this course is for all the system designers and software architects, including those working on system enhancements, who want to gain some hands-on knowledge of the best practice techniques to use when designing software solutions that meet business requirements. We’ll look at how requirements specified in a set of deliverables produced by business and system analysts can be achieved using models from the Unified Modelling Language (UML) and supported by more traditional approaches, like data normalisation. On top of that, the course will cover areas such as interface between analysis and design, logical process design and system controls and security.

Target Audience

Business analysts, project managers, solution and systems developers and anyone who requires a practical understanding of the models and methods of systems design. Systems Design Techniques is also a Specialist Practitioner module on the BCS International Diploma in Solution Development.
