System Modelling Techniques (Structured)

Prerequisites:

Those who need to model business systems using structured modelling techniques Those wishing to attain the ISEB Certificate in Systems Modelling Techniques. (These delegates should also book on course code SMTSEX-1). Candidates with special examination requirements should consult the ISEB web site (www.iseb.org.uk) for the ISEB Special Needs policy. Note that the ISEB must be advised at least four weeks in advance of any special requirements.

An understanding of the fundamentals of systems development.

Course Description:

In order to communicate system requirements clearly and accurately to both business and IT stakeholders, it is vital for analysts and designers to be able to construct models from a variety of perspectives. In most cases these models will provide the basis for more detailed design. The starting point for this course is a set of requirements, as defined in the Systems Development Essentials course. It is primarily concerned with modelling systems using structured techniques. It requires delegates to construct four main types of model reflecting different perspectives and to describe the interactions between them. At the end of the course delegates may sit an examination to attain the ISEB Business Systems Development certificate in Systems Modelling Techniques. (These delegates should also book on course code SMTSEX-1). This course may be taken as part of the programme leading to the ISEB Diploma in Systems Development.

This is an intensive four day course that places emphasis on the practical application of the modelling techniques covered. Delegates participate in exercises, and case study tasks. Those delegates taking the ISEB certificate will need to spend 60-90 minutes each evening on revision and example examination questions.

Skills:

• 
  
• Justify the need for modelling and modelling techniques.
• Explain why it is important to model system requirements from different perspectives and identify specific modelling techniques.
• Construct a static structure model (logical data structure, entity-relationship diagram).
• Construct a process model (data flow diagram).
• Construct a simple dynamic event driven model (entity-lifecycle diagram).
• Construct a simple user interface model (user conceptual model, web site navigation model).
• Evaluate how the various models reflect business objectives and system requirements (via critical success factors).
• Appreciate how the various perspectives inter-relate to each other.
