By Donna Knapp In the context of work, a role is typically defined as a set of responsibilities, activities and authorities granted to a person or team. While a role can, at times, represent a full-time job, this is not always the case. In the course of our work, many of us play different roles (i.e., we wear different hats). For example, we may play different roles within our teams (e.g., team lead or team member), or within practices (or processes) (e.g., practice owner, process owner, or practice/process practitioner), or in the context of a framework or methodology (e.g., customer, user, or sponsor; or product owner, scrum master, or scrum team member). Roles are important because they provide greater flexibility than job descriptions, which are often bound to formalized performance plans and perhaps even to contracts. This flexibility is important because organizations are increasingly adopting operating models that are more evolutionary and less structured than most companies h
