5 Use of Models in Requirements Engineering 10%
Candidates will be able to:
5.1 Explain the rationale for modelling the functional requirements (processing and data)
of an information system and describe how models help the analyst to:
5.1.1 Generate questions in order to clarify a requirement and remove ambiguity.
5.1.2 Define business rules.
5.1.3 Cross-check requirements for consistency and completeness.

represent the functional requirements for an information system, including the
following notational elements:
5.4.1 System boundary.
5.4.2 Actors (user role, another system and time).
5.4.3 Use cases.
5.4.4 Communication relationships (associations) between actors and use cases.
– It should be noted that there is no requirement to understand include and extend
constructs.
5.5 Interpret a UML Class diagram (comprising of classes, attributes, associations and
multiplicities) that represents the data requirements for a given scenario, and
describe the business rules that are represented.
– It should be noted that there is no requirement to understand operations,
association classes, generalisation (and associated concepts of inheritance and
polymorphism), aggregation and composition.
5.6 Explain the benefits to be derived from cross-referencing models and illustrate how
this can be achieved by using a CRUD matrix (of function or event against data).
