Homogeneity describes the situation in which a group, team or department has developed ONE particular way of thinking, acting and doing and A LOT of wrongs.

Other words to describe homogeneity would be groupthink, syncronicity, conformity, where one particular knowledge domain is allowed to dominate in any group or organisation.  Homogeneity is thus, according to The Innoversity Model, defined as the dominance of a single knowledge domain, independent of the number of other available domains or differences within a group.
