1. Use Case Model (40 marks)Analyse the case study to determine the high level functional requirements for the new system. Express your understanding of those requirements with:a. A use case diagram capturing at least all critical and significant use cases that the system will have to supportb. A document containing short use case descriptions for the use cases identified in the use case diagram.2. Domain Model (40 marks)Analyse the case study to determine the classes required to express the problem domains structure and operation. Express your understanding of the problem domain in:a. A domain model.3. State Machine (20 marks)Analyse the lifecycle and behaviour of the most complex stateful object* identified in your domain model and express its behaviour in:a. A state machine diagram*Note: a list of appropriate domain objects will be made available during semester. Please contact the lecturer to confirm your selection if you wish to complete this task before that list is available.RationaleThis assignment relates to the following:be able to analyse and verify system requirements;be able to produce and verify analysis and design models for a systemMarking criteriaUse Case ModelCriteriaFail (Bad)Pass (OK)Credit (Good)Distinction (Very Good)High Distinction (Excellent)How well does the Use Case Model address its intended purpose?Incorrect concept of use cases demonstrated.Short use case descriptions missing, largely incomplete, or generally wrong.Presentation poor, bad spelling and poor grammar in use case descriptions.Correct concept of ‘end-goal’ use cases demonstrated.Some critical or significant use cases identified, many missing.Some use cases inappropriately named.Some important/obvious external actors identified, many missing or misidentified.incomplete, or poorly described, some missing.Short use case descriptions generally consistent with use case diagram.Correct concept of ‘end-goal’ use cases demonstrated.Most critical and significant use cases identified.Use cases correctly named with short imperative action statements.
