ISEB Certificate in Systems Design & Implementation Techniques (3 day)

Course Overview

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.

Audience

This course is appropriate to designers working in all software environments, including those primarily working on system enhancements.

Examinations
