ISEB Systems Development Essentials

Course features

Systems Development Essentials is concerned with the fundamental skills of systems development in an Agile environment. Its focus is on systems investigation and quality assurance as these underpin all successful systems development. Systems Development Essentials with Agile also introduces the candidate to how the systems development effort could be organised. The course distinguishes between generic lifecycle types, methods and approaches.

Whilst exploring the fundamental differences between object-oriented and structured systems development, the course also focuses on the basic principles of agile systems development and it recognises how a commitment to software package implementation changes the structure of the systems development approach.

Combined with Systems Modelling Techniques with UML this course provides delegates with a complete systems analysis and development course.

Systems Development Essentials with Agile is delivered by trainers who bring their substantial experience of practical systems analysis projects to the programme. A comprehensive manual, containing detailed information about systems development techniques and providing references for further reading, is supplied as part of the course.

ISEB certificates

The course prepares participants to sit a one-hour, open book, examination leading to the certificate in Systems Development Essentials 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.
