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 different 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 BCS Certificate in Systems Modelling Techniques.
Following your exam you will be sent an email from BCS asking you to register for your exam. Once you have registered and your exam results become available then you will be able to log back into your account and view your results.
This course may be taken as part of the QA programme leading to the BCS International Diploma in Solution Development.
Prerequisites
An understanding of the fundamentals of systems development, or attendance Systems Development Essentials course.
An understanding of the fundamentals of systems development, or attendance Systems Development Essentials course.
This course is ideal for those who need to model business systems using structured modelling techniques and/or those wishing to attain the BCS Certificate in Systems Modelling Techniques.
At the end of this course you will be able to:
- 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 and access path analysis)
- Evaluate how the various models reflect business objectives and system requirements Appreciate how the various perspectives inter-relate to each other
