Specifically, as regards the role of the CEO, structures will assist those to attain superior performance by their corporations to the extent that the CEO exercises complete authority over the corporation and that their role is unambiguous and unchallenged. This situation is attained more readily where there is also chair of the board. Power and authority are concentrated in one CEO person. There is no room for doubt as to who has authority or responsibility over a particular matter. Similarly, the expectations about corporate leadership will be clearer and more consistent both for subordinate managers and for other members of the corporate board. The organisation will enjoy the classic benefits of unity of direction and of strong command and control. Thus, stewardship theory focuses not on motivation of the but rather facilitative, empowering structures, and CEO holds that fusion of the incumbency of the roles of chair and will enhance CEO effectiveness and produce, as a result, superior returns to shareholders than separation of the roles of chair and CEO.
