Assignment 2: Creating A Use Case

Assignment 2 Creating A Use Case

Using Microsoft Visio or an open source alternative such as Dia, create a use case graphic rendering that shows all actors and all use cases for the RMO CSMS marketing subsystem as shown in Figure 3-11 on pages 79-80 of the textbook. Provide a narrative describing your diagram that includes: an overview of the diagram and an analysis of the actors. Use at least three (3) quality resources outside of the suggested resources. Your paper must follow APA formatting, be double-spaced, in Times New Roman font size 12, with one-inch margins. Include a cover page with the assignment title, your name, the professor’s name, the course, and the date. The cover page and reference page are not included in the page length. Ensure diagrams created in Visio or Dia are embedded into the Word document before submission.

The creation of use case diagrams is a fundamental activity in systems analysis and design, providing a visual representation of the system's functional requirements and stakeholder interactions. For the RMO CSMS marketing subsystem, the development of a comprehensive use case diagram involves identifying key actors and illustrating their interactions with various system functionalities. This process not only clarifies system requirements but also facilitates communication among stakeholders and development teams, ensuring that all functional aspects are appropriately addressed.

In constructing the use case diagram for the RMO CSMS marketing subsystem, it is essential to first identify the primary actors interacting with the system. Actors represent external entities that engage with the system to perform specific functions. Based on the subsystem's scope, the main actors likely include the Marketing Manager, Customer, Sales Representative, and System Administrator. Each actor has distinct roles and responsibilities, which influence their respective use cases.

The Marketing Manager serves as the system's central stakeholder responsible for managing marketing campaigns, analyzing marketing data, and generating reports. The Customer interacts with the subsystem primarily to view marketing offers, inquire about products, and possibly provide feedback. The Sales Representative acts as an intermediary, entering customer data, processing sales, and accessing marketing information to support sales activities. The System Administrator maintains system integrity, manages user access, and handles system configurations and updates.

The use case diagram visually depicts these actors and their associated use cases, such as "Create Campaign," "View Offers," "Process Sale," "Generate Reports," "Manage Users," and "Provide Feedback." For instance, the Marketing Manager might interact with "Create Campaign" and "Generate Reports," while Customers access "View Offers" and "Provide Feedback." Sales Representatives may use "Process Sale" and "Access Marketing Data." The System Administrator handles "Manage Users" and "System Maintenance." These interactions confirm the functional requirements and stakeholder needs, which are critical for system development and enhancement.

Using tools like Microsoft Visio or Dia, the diagram's creation involves drawing actors as stick figures or labeled icons, linking them to relevant use cases shown as ovals or circles. The relationships, such as associations or include/extend dependencies, are represented with lines and appropriate annotations, providing clarity on system functionality and actor engagement. Ensuring all actors and use cases are included completes the visual model, aiding in system understanding and communication.

According to systems analysis principles, accurately identifying all stakeholders and their needs is critical for developing an effective use case diagram. This process involves participatory analysis with stakeholders and applying best practices from established methodologies, including UML (Unified Modeling Language) standards. Validating the diagram through stakeholder review ensures completeness and correctness, aligning the system design with business goals.

In addition to diagramming, a comprehensive narrative analysis contextualizes the use cases within the broader system environment. Describing how each actor interacts with the system's functionalities emphasizes user-system relationships and highlights areas for potential improvement. Furthermore, a literature review of at least three credible sources outside of course materials broadens understanding of best practices and standards in use case development and systems analysis. For instance, sources could include scholarly articles on UML modeling, industry reports on system stakeholder analysis, or authoritative texts on requirements elicitation and modeling techniques.

In conclusion, creating a detailed use case diagram for the RMO CSMS marketing subsystem enhances clarity in system requirements and stakeholder engagement. It provides a visual foundation upon which system design and implementation can be built, ensuring alignment with organizational goals and user needs. Incorporating best practices from reputable sources and validating stakeholder involvement ensures the resulting system is both functional and user-centered.
