"7.2 Contemporary Structures 2. What contemporary organizational structures are companies using? In recent decades, companies have begun to expand beyond traditional departmentalization methods and use matrix, committee, and team-based structures. Matrix structures combine two types of traditional organizational structures (for example, geographic and functional). Matrix structures bring together people from different functional areas of the organization to work on a special project. As such, matrix organizations are more flexible, but because employees report to two direct supervisors, managing matrix structures can be extremely challenging. Committee structures give authority and responsibility to a group rather than to an individual. Committees are part of a line-and-staff organization and often fulfill only an advisory role. Team- based structures also involve assigning authority and responsibility to groups rather than individuals, but, different from committees, team-based structures give these groups autonomy to carry out their work. 7.3 Using Teams to Enhance Motivation and Performance 3. Why are companies using team-based organizational structures? Work groups share resources and coordinate efforts to help members better perform their individual duties and responsibilities. The performance of the group can be evaluated by adding up the contributions of the individual group members. Work teams require not only coordination but also collaboration, the pooling of knowledge, skills, abilities, and resources in a collective effort to attain a common goal. Four types of work teams are used: problem solving, self-managed, cross-functional, and virtual teams. Companies are using teams to improve individual and group motivation and performance."
