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 selected UML techniques. It requires delegates to construct different types of model reflecting different perspectives and to describe the interactions between them.
Successful delegates 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 (eg class diagram)
- Construct a process model (eg activity diagram)
- Construct a simple dynamic event driven model (eg state chart)
- Construct a simple user interface model (eg web site navigation model)
- Evaluate how the various models reflect business objectives and system requirements (eg via critical success factors)
- Appreciate how the various perspectives inter-relate to each other
An understanding of the fundamentals of systems development, or attendance of QA's Systems Development Essentials course.
The need for modelling and modelling standards; Rationale for the selected approach; The approach and a Systems Development Lifecycle; Place of models within the Systems Development Lifecycle; Modelling the system from different perspectives; Interaction of the models; Validating and verifying models
Systems Modelling in Context
Monitoring analysis against business objectives and system requirements; The bridge to design, software package selection, and development
Use Case Modelling
Modelling user requirements; Use cases; Actors and the system boundary; Use case diagrams; Generalising actors and use cases; Use case associations; Use case descriptions Template, Pre- and Post-conditions, Main and alternative flows
Process modelling; Modelling use case descriptions
Static Modelling of Data
Analysis class modelling rationale; Objects and classes; Representing classes and encapsulation; Defining attributes; Associations; Generalisation, inheritance and abstraction; Class diagrams and object diagrams
State machine diagrams; Use case realisation; Introduction to communication diagrams; Sequence diagrams
Interaction of Models
Activity diagram and Use cases; Use cases and Class Model; State machine diagram and Use cases; Objects and Activity diagrams
Throughout the course a case study is used to allow delegates to practise the modelling techniques.
