Introduction to UML Class Diagrams - Case Study Example

SЕ STUDY СITY МЕDIСАL СЕNTRЕ (IТ) By Author The purpose The main purpose of the project is design a new computerized system. The current system includes: Patient record system, the patient and insurance billing system as well as the appointment scheduling system. All three systems have significant interaction among their business processes, so connecting them is a good way to increase the functionality of the system. The clinic’s staffs want to get some software to automate the process of mail sending as well as get software that can produce the postcards and mailing labels for the mails. Australian Medical Association is providing the codes for the clinic’s procedures. So, the new system should have the ability to get the codes, create the procedures’ code list and update already existing list. Another purpose of the system is help to collect data for creation of daily and weekly reports as well as help the accountant to collect the necessary information and create the status summary. Also, the system must have ability to process the electronic billings etc. The main goal is design a new computerized system that will join all of the systems to increase the functionality of the system. Stakeholders All the person involve in the system, either they are out of the organization either they are from the organization[Sta]. Internal External Operational IT department Staff (nurses, therapists etc.) Australian Medical Association Executive Manager of personal Patients Accountant Health Funds Post Bank Phone company(provider) Government Australian Tax Office Investors Stakeholders Roles and Responsibilities IT Department Maintenance of electronic equipment, LAN and WAN networks as well as maintenance of the web site clinics, etc. Staff Services to visitors Manager of personal Manage the clinic’s personal: hire, fire, change positions etc. Accountant control of all financial operations of the clinic, creation and providing the status summary etc. Australian Medical Association controlling the activities of the clinic, providing procedural codes, etc. Post Providing delivery service.

Government Granting of a license to operate, quality control, etc. Australian Tax Office Get taxes for all financial operations of the clinic. Investors Give money for the clinic; perhaps get some benefits from it. Patients Get the clinic’s services for free and paid.

Use Case Diagrams: These diagrams gives the overview of the different parts of the system, who is involve, and what effect that person on the system[UML]. User Case Diagram For Get the Appointment List Use Case User Case Diagram for getting the pay Use Case User Case Diagram for Patient Reminder Use Case Specify Use Case Descriptions for some (minimum of two) important Use Cases. Use Case Name Description Actors Send The Message Office Staff generate postcard from Computers, which are send to patient as a reminder, staff can remind the patient by SMSs when there is to come according to schedule. These reminders are usually sent twice in a month. Patient City Medical Center Staff Use Case Name Description Actor Produce Daily Reports This is the report which is generated from IT department for City Medical Center. This report includes appointment times, patient names, services to be received including the procedure code. IT Department City Medical Center Develop the Class Diagram for your system Class diagram shows different types of classes as abstract and concrete classes and their relationship. It shows each class name, its attributes and different methods for interfacing[Bru03]. Develop an Activity Diagram (AD) for one Use Case in your system These diagrams are used to show the activities, sequence, how the operation or activities are performed in a system[UML1]. Develop a sequence diagram (SD) for one Use Case in your system. These are interaction diagrams, which shows how interaction will be done between actors, and what type of messages and actions they perform[UML2]. Develop a State Machine Diagram (SMD) for a Class in your system How entities are communicate, what type of events are performed, are described in state machine diagram[Sta1]. Quality Assurance Statement Purpose For the satisfaction of the City Medical Center Staff, IT Department, patient of the Medical Center, our purpose is to provide excellent quality system to all of the stakeholders of the City Medical center. So that patient can be easily reminded, Staff can easily generate post cards, generate different report of high quality. These Quality Management activities must be sufficient to assure that the Project satisfies the needs for which it was undertaken and that Project risks are well understood and appropriately mitigated or managed. Quality Management Approach The approach to ensure that the appropriate quality management and risk management activities are conducted shall be based on the Project Management Institute’s (PMI) Standards. This includes activities of Quality Management that determine the quality policy, objectives, and responsibilities, and implements them by means such as quality planning, quality control, and quality assurance, and also manage the risks. Quality Check List 1. We prepare the schedule for excellent quality so that all tasks can be completed on time. 2. We ensure that all tasks are working according to the quality management plan. 3. We ensure that all the requirements are completing for every next task. 4. We ensure that all the standards are applying correctly. 5. We ensuring that all risk are properly managed.
