270 CHAPTER 4 SysML??”The Systems Modeling Language
The conform relationship is modeled between a view and a viewpoint ( Figure
4.60 ). The defi nition of views and viewpoints is coordinated with IEEE standard
1471 [3].
4.11.4 Problem
Defi nition
A problem documents an (potential) error or a flaw in the model or in the
modeled system.
It is a stereotype ?«problem?» of the UML element comment.
We usually discover real or potential problems that cannot be solved in an ad-hoc
way during the different system development phases??”analysis, design, implementation,
test, production, and operation. The model element problem allows us to
document this information in the model ( Figure 4.
