Homogeneity is the extent to which members are similar or different to one another. The difficulty for most project managers is finding the right balance between overly homogenous and overly heterogeneous. When evaluating team homogeneity, a manager can consider similarities and differences in personal characteristics, education, skills, abilities, generational backgrounds, cultural background, and income levels.
Teams that are homogenous tend to be highly cohesive and can easily develop effective communication methods that reduce conflict. However, too much homogeneity leads to greater instances of groupthink. Alternatively, teams that are highly heterogeneous have an advantage because members are highly diverse, which leads to more instances of creativity, ingenuity, and resourceful productivity. However, teams that are too diverse may limit the degree to which members can relate to one another and effectively communicate.
