Week 1 Discussion 1when Problem Decomposition Is Not Easy

Consider the development of a simple mobile application that displays personal financial management video clips selected from a central repository. Discuss how you would systematically analyze the requirements of this application and identify its problem components.

Explain how software engineering would help you identify the components and their interconnections.

Developing a mobile application that displays personal financial management video clips involves a systematic approach to requirements analysis and component identification, especially when the problem is complex or not straightforward to decompose. In this context, a structured method such as requirement elicitation, functional analysis, and design modeling facilitates understanding the core functionalities and segregating the application into manageable components.

Initially, requirements collection is essential, and this can involve stakeholder interviews, surveys, or observation to understand what users expect from the application. It is important to define both functional requirements—such as browsing videos, searching for specific clips, and viewing options—and non-functional requirements like security, usability, and performance standards. These requirements serve as the foundation for identifying problem components.

Once requirements are gathered, systematic analysis, such as data flow diagrams (DFDs) and use-case modeling, can be employed to depict how different parts of the application interact. For instance, the core components might include a user interface module, a video repository access layer, a search engine, user authentication, and personalization settings. These components are identified by analyzing the functional requirements—such as the need for user login, video browsing, and recommendation features—and technical constraints.

In complex applications where the problem is not easily decomposed, software engineering provides a set of methodologies to facilitate component identification and their relationships. Techniques like class and object modeling (using UML diagrams), modular design, and service-oriented architecture help organize the system into loosely coupled components that communicate through well-defined interfaces.

Furthermore, software engineering emphasizes the importance of establishing clear interfaces and communication protocols between components, thus ensuring that each module can be developed and tested independently. Architectural patterns like client-server or microservices enable scalable and flexible system structures, particularly crucial when dealing with multimedia content like video clips.

In conclusion, systematic analysis during requirements gathering, coupled with structured design methods such as UML modeling and architectural frameworks, assists in decomposing complex problems into manageable components. This approach ensures that the application can be developed efficiently, with clear understanding of each component’s role and the interconnection among them, even when initial problem decomposition is challenging.
