This chapter explains elements of organizational design that are vital for executing strategy. Leaders of firms, ranging from the smallest sole proprietorship to the largest global corporation, must make decisions about the delegation of authority and responsibility when organizing activities within their firms. Deciding how to best divide labor to increase efficiency and effectiveness is often the starting point for more complex decisions that lead to the creation of formal organizational charts. While small businesses rarely create organization charts, firms that embrace functional, multidivisional, and matrix structures often have reporting relationships with considerable complexity. To execute strategy effectively, managers also depend on the skillful use of organizational control systems that involve output, behavioral, and clan controls. Although introducing more efficient business practices to improve organizational functioning is desirable, executives need to avoid letting their firms become “out of control” by being skeptical of management fads. Finally, the legal form a business takes is an important decision with implications for a firm’s organizational structure.
