Organization is a way of gaining some power against an unreliable environment. The environment provides the organization with inputs, which include raw materials, human resources, and financial resources. There is a service or product to produce that involves technology. The output goes to clients, a group that must be nurtured. The complexities of the environment and the technology determine the complexity of the organization.
