Motivation/description
Why? The domain objects you are using in the object fl ow of activities have to be
described in order to ensure that all stakeholders reach a uniform understanding
and that they are used consistently in the model.
What? Model the structures of the domain-relevant terms from the system ??™ s view.
How? Model the terms and their structures as domain blocks in a block defi nition
diagram.
Where? The domain knowledge model refl ects the static view of the domain logic; it
is well suited for coordination with the principal and as a design basis.
Guiding questions
?–  What domain terms does the system deal with?
?–  Are the terms known to the principal?
?–  Is a term important enough to justify being explicitly modeled?
