A grouping of work for which someone is responsible or accountable. Not synonymous with a job title or occupation, though they may coincide, depending on the organization. For example, the work role of “software developer” may apply to those with varying job titles, such as software engineers, coders, and application developers. Conversely, multiple roles could be combined to create a particular job. This additive approach supports improved modularity and illustrates the fact that all learners in the workforce perform numerous tasks in various roles, regardless of their job titles.
