Hi$,$

Thank you for your answer.

Are these functionalities should be separate systems combined in the bigger system of HarmonyCare? Do they need to be reporesented as an expanded use case diagram? Or these are functionalities in one system?

Based on the case study, some key functionalities needed include:

Patient Registration: Register new patients into the system.

Appointment Scheduling: Schedule appointments for patients with healthcare providers.

Billing and Invoicing: Generate invoices for services provided to patients.

Inventory Management: Manage inventory levels and reorder supplies.

Case Study $$ HarmonyCare Limited HarmonyCare Ltd Hospital operates within the private healthcare sector, providing a range of medical services, including consultations, diagnostics, surgeries, and postoperative care in the UK and Germany. The hospital, with around $1000$ employees and $5$ branches in the UK and one branch in Germany, faces challenges in efficiently managing patient records, appointments, and billing across multiple locations. The current market demands advanced healthcare solutions to enhance patient care, streamline operations, and ensure compliance with regulatory standards. However, their existing system lacks of a centralized patient registration system which leads to inconsistent patient data across different departments and locations. Duplicate patient records are created, causing confusion and potential medical errors. Manual handling of patient registration process results in slower workflows and increased administrative burden. There are the reports of overbooking appointments, leading to longer waiting times and dissatisfaction among patients. There are the challenges in allocating resources such as doctors, rooms, and equipment optimally. Patients and healthcare providers face difficulties in receiving timely notifications and reminders about appointments. Their current billing processes increase the likelihood of errors in invoicing, leading to discrepancies in charges and potential financial issues for both patients and the healthcare facility as well as has resulted in delayed processing of bills, impacting the hospital's cash flow and financial stability. Their inventory tracking also makes it challenging to forecast demand accurately, leading to difficulties in planning timely reorder of supplies. Now HarmonyCare has recognized the need to develop an optimised system to address these challenges by automating key processes, improving data accuracy, and providing a centralized platform for seamless information exchange between branches. Requirement With reference to the case study and the new system under proposal: Analyse the business environment stating its current market, services, and problems as well as the benefits of the new system. Recommend an SDLC model for the new development, clearly stating, in relation to the case study, why this has been chosen over the other models.
