Create A Use Case Diagram For The Crm System Following The Uml Guideli

Create a Use Case Diagram for the CRM System following the UML guidelines in Appendix A of the textbook. Doc sharing Project Workbook - Week 7 folder, has instructions on how to create a Use Case using Visio (but you can use any MS Office application). Need to include processes for Record Customer Activities, Send Promotions, Generate Point Redemption Coupons, and Generate Customer Reports processes. The hint is to look at the external entities, processes, and data stores from the Level 0 DFD on page 187. Actors: The Customer is a source and a sink - and should be shown as one Actor on our Use Case.

The three data stores will be the other actors: Customer Activity Records. Marketing Database. Product Database. Process: Each of the sub process on page 187 will become a Process reflected in the Use Case. So we have a total of four processes.

Send Promotions. Generate Point Redemption Coupons. Record Customer Activity. Generate Customer Reports. Actors will interact with the processes on the Use Case based on the data flow arrows on the Level 0 diagram. For Example: Product Database Actor will connect to the Generate Customer Reports process as shown on the bottom right of the Level 0 diagram on page 187.

Introduction

The development of a comprehensive Use Case Diagram (UCD) for a Customer Relationship Management (CRM) system is fundamental for visualizing the system’s functional requirements and understanding user interactions. UML (Unified Modeling Language) guidelines promote clarity and precision in representing system functionalities and external interactions. This paper delineates the process of creating a UML-compliant Use Case Diagram for the CRM system, integrating the specified processes and actors based on the Level 0 Data Flow Diagram (DFD) on page 187 of the referenced textbook. It emphasizes the importance of accurately depicting actors, data stores, and processes to facilitate effective system analysis and design.

Understanding the System and Guidelines

The CRM system under review interacts with various external entities and internal data stores. The external entities include the customer, who functions both as a source and a sink of data, and the system must portray this actor as a single entity. Internal data stores include Customer Activity Records, the Marketing Database, and the Product Database, which serve as actors for certain processes. The key processes identified are Record Customer Activities, Send Promotions, Generate Point Redemption Coupons, and Generate Customer Reports. These processes are derived from the Level 0 DFD, ensuring consistency between data flow and functional representation.

Following UML guidelines, each process is modeled as a use case, with actors depicted as stick figures indicating interaction points. The data stores and external entities are represented as actors to demonstrate data exchange. The interactions are depicted via association lines, with arrows pointing from actors to the use cases they initiate or receive data from. This visual structure guarantees clarity in understanding how each actor interacts within the system.

Developing the Use Case Diagram

The first step involves identifying the primary actors:

- The Customer: Acts both as a source and sink, involved in activities like receiving promotions and activity reporting.

- Customer Activity Records: Maintains customer interaction history.

- Marketing Database: Stores promotional and marketing data.

- Product Database: Contains product details relevant for report generation and promotions.

Next, the four core processes are modeled as use cases:

1. Record Customer Activities

2. Send Promotions

3. Generate Point Redemption Coupons

4. Generate Customer Reports

Each process is associated with relevant actors, based on data flow. For example, the Customer interacts with 'Send Promotions' and 'Record Customer Activities' processes. The Product Database connects primarily to 'Generate Customer Reports' as a source of product information required for reporting. Similarly, the Marketing Database interacts with 'Send Promotions' and 'Generate Customer Reports.'

The Use Case Diagram visually represents these interactions, connecting actors and use cases with lines to depict communication and data exchange pathways.

Conclusion

Creating an effective UML Use Case Diagram for the CRM system involves understanding the system’s data flow, external entities, and core processes. By leveraging the Level 0 DFD as a reference, the diagram offers a clear visualization of how actors interact with various system processes, facilitating system analysis and design. Adhering to UML standards ensures the diagram's usability for system documentation, stakeholder communication, and future development efforts.
