ISEB Systems Design & Implementation - 3 days

Systems Design & Implementation Techniques takes a 'tool-kit' approach to systems design, presenting models from the Unified Modeling Language (UML), such as sequence diagrams and state machine diagrams, alongside established models like the normalised data model and structured English. It is appropriate to designers working in all software environments, including those primarily working on system enhancements. The aim is that, at the end of the programme, participants will have a good understanding of the models and methods used but, more importantly, will be able to apply them in project situations.

Systems Design & Implementation Techniques is delivered by trainers who bring their substantial experience of practical systems design projects to the programme. The case study on which the course is built is based on a genuine assignment. A comprehensive manual, containing detailed information about systems design techniques and providing references for further reading, is supplied as part of the course.

Systems Design & Implementation Techniques prepares candidates to sit the examination for the ISEB Certificate in Systems Design & Implementation Techniques. This involves a one-hour, open book examination that may be taken at the end of the course or at a public examination session.

The certificate in Systems Design & Implementation Techniques is a core module for the ISEB Diploma in Systems Development.

The exam fee is included within the course price.
