IT 304 Module Three Activity Guidelines and Rubric
In this module, you learned that users of a new system and system analysts work together to develop and model the requirements of a system. You also learned that use case diagrams support the visualization of both requirements and design of a software system. Use case diagrams are considered to be high level to help stakeholders and users understand the system. Meanwhile, use case specifications are low level, and are intended to be used by the developers coding the program. For this activity, you will create use case diagrams and their use case specifications.
Prompt
Imagine you are an employee of a consulting firm. The consulting firm was hired to design a new system that will better automate how a patient checks into a patient care facility for medical services. Part of the consulting services that you will provide include developing use case diagrams and their use case specifications that demonstrate how the various actors will use the IT system. UML should be used to illustrate how the software solution should facilitate certain check-in/check-out services for a patient.
For this week’s activity, you will create:
Use Case Diagrams: The four use case diagrams must illustrate the check-in/check-out process of the patient at the clinic. They must include an identification of:
Actors
Relationships between the actors
System boundaries
Use Case Specifications: The four use case specifications must apply the features, functionality, and operations in the software solution mentioned in the business case.
All required use case diagrams and their use case specifications must be complete, without any missing components, as you will be graded on completion.
The four key services that you will create use case diagrams and use case specifications for are:
Capture patient information/reason for visit
Verify patient insurance
Capture patient copay
Schedule next appointment
You can use a tool of your choice to help you create the use case diagrams, but we recommend using Lucidchart, draw.io, or MS Visio. The following resources can help you complete your use case diagrams:
