Final answer:
The question pertains to project management or business processes where roles can have defined 'Skills' and 'Mandatory Skills' for cases, which are projects or client engagements. These compulsory skills are essential for effective job performance in various roles, such as software development or customer service.
Step-by-step explanation:
When a student inquires about specific roles that can define both Skills and Mandatory Skills on cases, it suggests they are seeking insight into business processes or project management frameworks where roles come with sets of required expertise. In many business scenarios, especially in fields like IT or consulting, a 'case' may refer to a project, client engagement, or a problem-solving scenario. Within this context, roles indeed can specify certain skills as mandatory. Additionally, this kind of discussion might also be part of a Human Resource Management system where roles have designated skills that are considered mandatory for successful job performance.
The concept of 'mandatory skills' implies that a person in a specific role must possess a certain skill set to complete their responsibilities effectively. For example, a software developer's role might require mandatory skills in coding languages such as Java or Python. Even in customer service roles, certain skills like effective communication or problem-solving could be marked as mandatory.
