construction organization and the external environment

Think about the construction organization and the external environment. How would you briefly describe the construction organization’s task and general environments? With the changes in those environments and the changes that organization has experienced, how has it responded to its changing environment? How has it been successful or unsuccessful?
Discuss the sources of power in an organization. What are the sources of organizational power in the construction organization? In particular, describe those sources of power other than power granted through formal position.
