Groups created by managerial decision to accomplish stated goals of the organization are called?

The correct choice is formal groups, as these are established by an organization to achieve specific goals or objectives. Formal groups are characterized by a defined structure, specific roles, and are created through the directives of management or organizational policies. Members of formal groups typically have designated tasks and responsibilities, which contribute to the organization’s overall mission and objectives.

In a formal group, there are often established protocols and reporting relationships, which help ensure that the group's activities align with the organization's goals. This structure aids in efficiency and accountability, as members are aware of their roles and how they fit into the larger organizational framework.

While task groups are also designed to achieve specific outcomes, they tend to be temporary and focused on particular projects, which differentiates them from formal groups that can have a broader and ongoing purpose within the organization. Informal groups arise spontaneously and are based on personal relationships or shared interests rather than organizational mandates, thereby lacking the formal structure and objectives set by management. Interest groups may be formed around common interests but do not typically align directly with organizational goals in the way that formal groups do.
