When designing an object-oriented application, who should write a description of the problem domain?

In the process of designing an object-oriented application, several roles come into play, such as project managers, software architects, developers, and domain experts. Each of these roles has specific responsibilities and contribute to different aspects of the application design. It's important to know these responsibilities in order to determine who should write a description of the problem domain.

Let's briefly define the roles and their main responsibilities: 1. Project managers are responsible for overseeing the entire project, managing resources, and ensuring that the project stays on schedule and within budget. 2. Software architects design the overall structure of the application and make high-level decisions about the technologies and patterns to be used. 3. Developers implement the application according to the requirements and the design provided by the software architect. 4. Domain experts are individuals who have deep knowledge and expertise in a specific problem domain. They provide crucial insights and input to guide the project team in accurately representing the problem domain in the application.

Based on the responsibilities defined above, it is clear that domain experts are the ones with the required knowledge to write a comprehensive description of the problem domain. They understand the nuances and specific constraints of the domain and can provide the information necessary for the software architects and developers to design and implement an appropriate solution within the object-oriented application. So, the answer to the given exercise is: Domain experts should write a description of the problem domain when designing an object-oriented application.
