The physical structure of any business is important as it imposes oper- ating constraints (practical rules for how resources work and combine to deliver products and services) on managers. However, the effect of oper- ating policies (managers' decision-making processes related to the level of INTRODUCTION coordination and development of activities related to the value chain of the firm) is more relevant to the dynamic behavior of industries because oper- Porter (1998) suggests that not only do investment decisions make it hard ating policies regulate the competitive behavior of firms and, through the to forecast with certainty the equilibrium of industries, but also industries interconnections existing in the market, of the industry.
