In order for a team to be successful team roles need to be understood and redefined to fit today 's corporations. Some define (Biddle, as cited in Fulmer, Ingrid, Hollenback, Murray & Stewart, 2005) roles as a set of behaviors that are interrelated with repetitive activities of others and characteristic of the person in a particular setting. From this definition it can be seen that roles are a combination of interactions between team members that result in teamwork. Team roles are also defined as being a single role for a single member. However, in today 's changing workplace team roles should be flexible positions.
