Final answer:
The correct answer is option 4. The specific area of the user's business need that is within the scope of the new system is called the problem domain. It involves identifying customer needs, constraints, resources, and forming a clear problem statement that guides the design process.
Step-by-step explanation:
The specific area of the user's business need that is within the scope of the new system is referred to as the problem domain. Defining the problem domain is a critical step during the initial phase of a design or development project. It encompasses understanding the needs of potential customers, identifying possible constraints such as technological limitations or government regulations, and recognizing the resources available to navigate the design challenge. These elements are then transformed into a problem statement, which expresses a clear understanding of the scope and limitations of the project.
A problem domain outlines what the new system aims to address, including the boundaries of what it should do (functional requirements) and how it should perform within the given constraints. For instance, identifying constraints like budget, time, and available personnel is vital to tailoring the design solutions that fit within these parameters. This process ensures that the final design fulfills the user specifications and aligns with the use cases that depict scenarios in which the system will be utilized. Ultimately, the problem domain guides the development of a prototype, which is tested and evaluated to ensure it meets the client's needs and operates effectively within the specified constraints.
