What term describes the relatively stable capabilities people have to perform various related activities?

The term that describes the relatively stable capabilities people have to perform various related activities is "ability." This concept refers to the underlying capacity or potential that an individual has to perform tasks, learn new skills, and adapt to different situations effectively. Abilities are often seen as innate or developed through experience and practice and encompass a wide range of functions such as cognitive, emotional, and physical capabilities.

In a workplace context, understanding an individual's abilities is crucial for effectively assigning roles, responsibilities, and opportunities for development. Recognizing a person's abilities can help organizations design training programs, select suitable candidates for specific tasks, and enhance overall organizational performance.

While "skill sets," "talent," and "expertise" are related terms, they do not precisely capture the definition of stable capabilities. Skill sets refer to the specific skills a person possesses for particular tasks; talent usually implies an inherent aptitude for certain activities, and expertise denotes a high level of knowledge or proficiency in a specific area developed over time. Abilities serve as a broader concept that encompasses these more specific terms.
