Final Project Milestone Three System Requirements Submit

6 2 Final Project Milestone Three System Requirementsubmit Your Syst

The system requirements model is to be submitted as a Word document that is a combination of sections: a requirements model, a data process model, a data flow diagram, a data dictionary, an object model, and a use case diagram. Copy the image of your diagram into your Word document and include text to ensure that the diagram has proper context within the overall system requirements model through written explanations. Your audience is IT management and the IT project team.

Detail the specific requirements of your case, including outputs, inputs, processes, performance, and controls (security). Create visual representations of all relevant data processes, data flow, data dictionary annotations, object modeling, and use case diagrams, each with accompanying explanations that relate these models to your system requirements. Incorporate relevant diagrams, charts, and tables, and ensure clarity in communication.

Follow the formatting guidelines: 4–6 pages, double-spaced, 12-point Times New Roman font, one-inch margins, and APA citations. Your submission should comprise the components outlined, each organized under a specific section header.

Paper For Above instruction

The development of a comprehensive system requirements document is essential to establishing a clear understanding between the stakeholders and the development team. For this project, the focus is on creating a detailed and integrated model that captures all critical aspects of the proposed system based on the selected case study problem. This paper presents the system requirements in a structured manner, including textual descriptions and visual diagrams, to facilitate communication and verification.

Introduction

The chosen case study involves the implementation of a customer relationship management (CRM) system for a mid-sized retail business. The core problem revolves around inefficient customer data management, which hampers personalized marketing efforts, customer service, and sales tracking. Stakeholders such as sales representatives, marketing staff, and IT administrators require a streamlined and accurate system that consolidates customer information, automates processes, and enhances data security. The audience for this requirements document includes the IT management team, responsible for approving system design and overseeing implementation, and the IT project team, tasked with developing, testing, and deploying the system.

Requirements Model

The requirements checklist encompasses essential aspects grouped into inputs, outputs, processes, performance, and controls:

  • Inputs: Customer personal information, purchase history, contact preferences, and feedback data.
  • Outputs: Customer profile reports, targeted marketing lists, real-time dashboards, and notifications for sales actions.
  • Processes: Data entry and validation, customer segmentation, automated marketing campaign execution, and reporting.
  • Performance: System should process customer data within 2 seconds, handle at least 10,000 records efficiently, and provide 99.9% uptime.
  • Controls: Data encryption, user authentication, role-based access control, audit trails, and compliance with GDPR.

Process Model

The context diagram, created in Visio, centers on the CRM system interacting with four entities: Customers, Sales Staff, Marketing Department, and IT Administrators. Data flows include customer inquiries, order information, marketing campaign inputs, and system maintenance requests. The process illustrates how these entities interact with the core system while exchanging data streams suitable for fulfilling specific activities. This model highlights the system's role in managing customer data lifecycle, from input collection to reporting.

Data Model

The primary data process involves a Customer Data Store (CDS). The DFD diagram shows how this data store connects with processes such as Customer Data Entry, Data Validation, and Report Generation. The diagram emphasizes the flow of customer information, such as personal details, purchase history, and communication preferences, through various system modules to support personalized marketing and support services. The visual representation facilitates understanding of data movement and storage within the system.

Data Dictionary

  • CustomerID: Unique identifier for each customer.
  • Name: Full name of the customer.
  • Email: Customer's email address.
  • PhoneNumber: Contact number.
  • PurchaseHistory: Record of all transactions.
  • Preferences: Customer communication and product preferences.
  • Feedback: Customer feedback comments and ratings.

Use Case Model

The use case diagram delineates interactions such as "Login," "Update Customer Profile," "Generate Report," and "Send Marketing Campaign." Actors include Customer, Sales Staff, Marketing Staff, and System Administrator. Each actor's description correlates with their respective responsibilities, illustrating how they leverage system features. For example, Sales Staff can update customer details and view reports, while Marketing Staff can execute targeted campaigns.

Object Models

A state transition diagram illustrates the Customer entity moving through states: New, Active, Inactive, and Churned. The sequence diagram demonstrates the process for a Sales Staff member updating a customer profile, including steps for login, data validation, and confirmation. These models reveal system dynamics and interactions, clarifying process flows and actor responsibilities within the solution.

Summary and Conclusion

This requirements document provides a comprehensive overview of the proposed CRM system, integrating textual descriptions with visual diagrams such as context models, data flow diagrams, data dictionaries, use case, and object models. Taken together, these components establish a clear blueprint that addresses stakeholder needs, ensures security and performance standards, and delineates system functionalities. The detailed requirements serve as a foundation for subsequent system design, development, and implementation phases, instilling confidence that the solution aligns with organizational goals and user expectations.
