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 Modeling 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.
Presented to you by one of the expert training consultants pictured below, each member of our Systems Design Techniques training team bring their substantial experience of software development and systems design to the programme.
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.
COURSE PREREQUISITES:
One thing to bear in mind is that although you don't necessarily need to have any existing knowledge in order to take this module, we do strongly recommend that, given the amount of technical material covered on the course, you have at least a basic understanding of the UML. And in particular, we suggest class models, use case models and interaction models (sequence diagrams). If you're worried that you might not have the right basic knowledge, get in contact and we can see what options are available.
