Teamwork and effective group functioning. The need to work together in project teams is common in creative environments. Depending on the company, teams depending on the nature of the project, their expertise, the challenge that senior colleagues aim to set to junior staff, and so forth. Staff may join different teams in order to promote a fresh perspective and encourage employees to stretch their work capabilities and interpersonal skills. Tushman and O'Reilly (2002) note that employees need to be encouraged to work and communicate effectively, and that implementation is enhanced when teams work harmoniously, communicate well and have common goals.
