August 16, 2017 Hilda Checkpoints: Analysis Class Artifacts > Analysis & Design Artifact Set > Analysis Class > Checkpoints The analysis class name is unique. The class is used in at least one collaboration. The class’s brief description captures the purpose of the class and briefly summarizes its responsibilities. The class represents a single set of cohesive responsibilities. Responsibility names are descriptive and the responsibility descriptions are correct. The responsibilities of the class are consistent with the expectations placed upon it by collaborations in which the class participates. All classes needed to perform the use cases (excluding design classes) have been identified. All actor-system interactions are supported by some boundary class. No two classes possess the same responsibility. Each analysis class represent a distinct set of responsibilities, consistent with the purpose of the class. Relations between use cases (include, extend, generalization) are handled in a consistent way in the analysis model. The complete lifecycle (creation, usage, deletion) of each analysis class is accounted for. The class fulfills the responsibilities required of it, either directly or through delegation. Classe collaborations are supported by appropriate associations. All requirements on the class have been addressed. If the class is a boundary class, all the requirements of the actor have been addressed (including input error).
