Each of these four attributes defines a point on the diamond of national advantage; the effect of one
point often depends on the state of others. Sophisticated buyers will not translate into advanced products, for example, unless the quality of human resources permits companies to meet buyer needs. Selective disadvantages in factors of production will not motivate innovation unless rivalry is vigorous and company goals support sustained investment.
At the broadest level, weaknesses in any one determinant will constrain an industry's potential for advancement and upgrading.
