Assignment Title: Optimizing Business Processes through Information System Design

Assignment Overview:
You have been provided a list of case studies that your group should select one of them. You can find this in the Group assignment case studies.pdf. In this Assignment, your group will focus on identifying inefficiencies in one of these. business's existing processes and designing an information system to optimize these processes. The goal is to create a system that improves operational efficiency, reduces costs, or enhances service delivery.

Assignment Tasks and Deliverables:

Assign roles: Project Manager, Business Analyst, System Architect, Data Modeler, and (if needed) Prototype Developer.

Task 1: Business Process Analysis and Requirements Gathering:
Business Analyst: Identify a business with operational inefficiencies and conduct research to gather system requirements.
Project Manager: Oversee the research process, ensuring that all relevant stakeholders are interviewed, and all necessary data is gathered.
Deliverable:
Introduction to the selected project and system description
Objectives of project
Requirement specification (functional and non-functional) and constraints
Description of the proposed system
Logical model design
Data flow diagrams - Context diagram
Data flow diagrams - Diagram 0/Diagram [Diagram 1 is optional]
Data dictionary for all the data stores in level 0 DFD and any 3 selected dataflows of your choice.
You should identify at least 3 inefficiencies and gather 4 requirements.

Task 2: Process Modelling and System Design:
System Architect: Design process models (e.g., Data Flow Diagrams, Use Case Diagrams) based on the requirements gathered.
Data Modeler: Develop data models (e.g., Entity-Relationship Diagrams) to represent the data flow and storage needs of the system.
Deliverable: process models, data models, and an initial system architecture.
Object Oriented Modelling Use a suitable UML diagramming software such as Visual Paradigm (community edition) or Lucid charts to model the following diagrams of your selected project. Hand-drawn diagrams or diagrams developed using office suits are not accepted. Based on your project requirements, you may include the entire model in one diagram or subdivide the model into several subsystem diagrams.
Use case diagrams
Activity diagrams - select at least 2 main use cases from your project and develop activity diagrams
Class diagram
System sequence diagrams - select at least 2 main use cases from your project and develop system sequence diagrams
User Interface Design an overall user interface consisting of screens, commands, controls, and features to enable users to use the system. Choose at least 4 main functionalities of your project to develop user interfaces. Your design should demonstrate how data will be input to the system? That includes the physical layout for input, the input design and procedures, and how data will be output from the system. Use suitable wireframing software such as Lucid Charts online wireframe tool, Balsamiq Wireframes, or figma.com to design your interfaces.

Task 3: System Architecture and Prototyping:
System Architect: Finalize the system architecture, detailing how different components of the system interact.
Prototype Developer: Create a basic prototype or mock-up of the system, focusing on key interfaces and functionalities.
Deliverable: The finalized system architecture, prototype screenshots, and design documentation.
