A use case diagram and descriptions - draw a use case


Assessment 1 - Task

Background: NewAccess is a mental health intervention which initially targeted youth aged 17 to 25, and is in the process of being expanded to young people as young as 12, and also to Indigenous youth. Headspace is one of several organizations trialing this new system. NewAccess particularly targets depression and anxiety. One of the problems identified was that a young person with a mental illness might see multiple professionals before getting the help they need. Each time they need to re-tell their 'story. Soon the young people clam up and say very little, making it harder for professionals to help them. Initially, they might see a Headspace caseworker, then medical staff in a hospital emergency department, perhaps a General Practitioner, a psychologist, a psychiatrist, and others.

Imagine that you are the analyst tasked with building a system that will capture the 'story' the first time it is told. This will give access to successive professionals, so that case notes and the story can become enriched, and the young person can be assisted more appropriately. An evaluation of the initial NewAccess trial is available under the 'Resources' tab of the subject Interact site.

Complete the Following - You are a Systems Analyst that is part of a project that is being currently being proposed. Your task is to develop a Vision Document for this project.

You are to describe the problem in your own words, and the capabilities and benefits. You need to create a Project Vision Document which contains:

  • Problem
  • Capabilities
  • Benefits

Specific analysis techniques have not been taught yet, so this assignment does not require technical descriptions.

Rationale - This assessment task will assess the following learning outcome/s:

  • be able to describe the context of an information system.
  • be able to formulate and justify system requirement models based on evaluation of given situations.

This assessment aligns with learning outcomes

  • be able to describe the context of an information system;
  • be able to distinguish between requirement gathering techniques and combine these appropriately to apply to a real scenario;
  • be able to evaluate development requirements and prepare a feasibility proposal based on multi-disciplinary (financial, human resource, technological) analyses.

Assessment 2 - Task

Further background - Refer to background information provided in Assessment 1 regarding the NewAccess project. Headspace in NSW was one organization tasked with trialing NewAccess with people aged as young as 12. In 2005 the Australian Government allocated S54 million to establish the National Youth Mental Health Foundation (later to be named Headspace). "Our brief is to make sure services are available at the earliest possible point when problems emerge. The criteria to get help is pretty simple - you must be 12 - 25. That's it." Aimed to address the health and well-being concerns of young people by providing a holistic platform for care. This would give teenagers and young adults comfort that their support will be coordinated and integrated across primary and specialist care, and not just focus on the 'illness' but also social inclusion and recovery.

Youth assigned to a headspace caseworker may subsequently be admitted to the Emergency Department (ED) of the local regional hospital. Currently there the no requirement for the ED staff to notify the headspace caseworker when a client has been released. Sometimes caseworkers are notified, but often not. It means that days and even weeks can transpire before a caseworker becomes aware of that release. In the meantime, the young person tends to return to the environment and circles of influence that led to the mental health problems in the first place, without the coping and support mechanisms that a caseworker can provide.

Complete the Following - Please refer to the marking guide when preparing your response to see what criteria and standards will be used to assess your work and your progress.

Consider that the system is being built for a regional Headspace center in NSW, that is trialing NewAccess with youth as young as 12. The system will need to capture the 'story' the first time it is told, and give access to successive professionals, so that case notes and the story can become enriched, and the young person can be assisted more appropriately. You are the business systems analyst assigned to the project, you will need to produce:

A stakeholder map

  • Draw stakeholder role names on a stakeholder map with 4 quadrants, Internal-Operation, Internal-Executive, External-Operation, External-Executive
  • For each stakeholder, describe why they have an interest in the project.

A questionnaire -

Create one questionnaire that you would send to one stakeholder group with an aim to help you identify further details about the environment, the problem area and/or how the system would operate to help solve the problem.

  • Identify which stakeholder you are going to send the questionnaire to.
  • Write an introduction statement that will go with the questionnaire explaining the purpose of the questionnaire.
  • Write 10 questions, either open and/or closed-ended questions.
  • This should be written as a questionnaire that could be distributed.
  • Only write the questions, you should not write the answers.

A Use Case diagram and descriptions

  • Draw a use case model for the information system.
  • Write brief Use Case descriptions for each Use Case in the diagram.
  • Write one fully developed Use Case description for one of the important Use Cases identified. Select an important Use Case that is a key part of the system, not a basic simple Use Case.

Rationale - This assessment task will assess the following learning outcome/s:

  • be able to describe the context of an information system.
  • be able to compare and contrast the different methodologies of systems analysis and evaluate their appropriateness for different and complex situations.
  • be able to distinguish between requirement gathering techniques and combine these appropriately to apply to a real scenario.
  • be able to formulate and justify system requirement models based on evaluation of given situations.
