“A natural companion to the competitive advantage is the synergy component of strategy. This requires that opportunities within the scope possess characteristics which will enhance synergy.”

“This theory maintains that the objectives of the firm should be derived by balancing the conflicting claims of the various 'stakeholders' in the firm: managers, workers, stockholders, suppliers, vendors. The firm has a responsibility to all of these and must configure its objectives so as to give each a measure of satisfaction. Profit which is a return on investment to the stockholder is one of such satisfactions, but does not receive special predominance in the objective structure,”

“We shall approach practical objectives through a series of approximations. Keeping the maximization of the rate of return as the central theoretical objective, we shall develop a number of subsidiary objectives which contribute in different ways to improvement in the return and which are also measurable in business practice. A firm which meets high performance in most of its subsidiary objectives will substantially enhance its long-term rate of return. As will be seen, this road has its own obstacles: the difficulties of long term maximization are replaced by the problem of reconciling claims of conflicting objectives.”
