Introduction

Fundamental Modelling Concepts (FMC) diagrams and Use Case Diagrams are two of the most important tools in system design. Fundamental to comprehending, organizing, and conveying a system's finer points are such visual representations. Here, we'll investigate the value of such diagrams and how they contribute to the creation of systems that meet the requirements of their end users.

A system's design, flow of information, including external dependencies may be better comprehended with the use of Fundamental Modelling Concepts (FMC) diagrams, which offer a thorough visual depiction of the system's components and how they interact with one another. Not only do they play a crucial part in easing conversation, but they also make sure no important aspects of the system are overlooked when it comes to planning.

Use Case Diagrams, demonstrate how users interact with the system from the user's perspective. These diagrams are useful for establishing boundaries, outlining how a system works, and meeting the requirements of the end users. They play a critical role in translating high-level needs into actionable design decisions by facilitating clear communication among designers, developers, and stakeholders.

By delving further into these crucial resources, we'll show why they're so important in system design, using examples from the course and other sources to back up our claims. The development of well-organized, user-centered systems that meet the needs of stakeholders relies heavily on FMC as well as Use Case Diagrams.

Requirements Matrix and Requirements Elicitation:

Requirements Elicitation:

• What do you admire about your rivals' websites that you would like to see in  own online shop? This will aid in identifying features that the customer values most.

• After researching other online merchants, have you identified any areas where you feel you might provide better service to your customers? The purpose of this inquiry is to help the customer identify potential weak spots in their website.

• Have you found any best practices for user interaction or support in other e-commerce platforms that you'd want to see incorporated into your own? The more we learn about these objectives, the more we'll be able to identify the features we'll need to achieve them.

• When communicating with clients, have you run across any problems or restrictions with the features of your present website? This will aid in pinpointing problem areas and setting priorities for change.

FMC Diagram

System designers can't get by without knowing how to draw a Fundamental Modelling Concepts (FMC) diagram. To better understand the structure of the system, data flow, as well as external dependencies can refer to this diagram, which gives a visual depiction of these aspects. It provides a big picture view of the system, which is essential for doing proper design work. In addition, the FMC diagram helps in figuring out the system's ecosystem by locating its external interfaces, including service providers (Hussin et al, 2022). A well-structured and efficient system is the product of careful consideration of all key components and their interactions, which may be communicated effectively through the use of the FMC diagram.

Use Case Diagram

System designers must draw a Use Case Diagram because of its many useful applications. First, it offers a succinct visual depiction of the system's external (business-to-consumer) and internal (staff) user interactions. This graphical representation helps users grasp the fundamental features and needs of the system. Second, the graphic clarifies the scope of the system by showing what kinds of activities fall inside its purview. This is crucial for ensuring that the design process takes into account all necessary user actions and system functionality (Dehning et al, 2020). An good Use Case Diagram may assist designers, developers, and stakeholders have productive conversations that result in a system that better satisfies end-users' requirements and expectations.

Use case specification

System design relies heavily on artefacts like Use Case Diagrams and Fundamental Modelling Concepts (FMC). To better comprehend system architecture, data flow, and external dependencies, stakeholders can refer to FMC diagrams for a visual depiction of system components and their interconnections. Use Case Diagrams show how users engage with a system from their perspective. These diagrams are useful for establishing boundaries, outlining how a system works, and meeting the requirements of the end users.

The importance of such diagrams in system design is further emphasized by examples found in textbooks and outside studies. They play an important role as tools for successful communication between designers, developers, and stakeholders (Amit & Zott, 2020).. Systems that are well-structured, user-focused, and aligned with the expectations of stakeholders can benefit from both FMC and Use Case Diagrams since they aid in turning abstract requirements into practical design decisions.

Conclusion

In conclusion, Use Case and Fundamental Modelling Concepts diagrams are indispensable tools for successful, focused on users, as well as organized system design. System design, flow of information, including external relationships may all be grasped with the use of FMC diagrams. As effective means of information exchange, they improve system design by ensuring that all relevant parts and connections are taken into account.

Use Case Diagrams  focus on the user while still helping to define the system's boundaries and its capabilities. Collaboration among  stakeholders is facilitated by these diagrams, resulting in systems that meet users' requirements.

 The importance of FMC and Use Case Diagrams in system design cannot be overstated, as they play an important part in the development of effective, user-centric systems.
