A company may experience a reduction in the quality of products due to decentralization of core business operations and, subsequently, decreased profits. Operation costs may be higher due to supplier competition which may have kept costs low. Moreover, other factors that may come up and discourage a company to go for vertical integration are suppliers who may order less than the lowest cost-efficient scale needed to produce the product. Vertical integration may also be discouraging where there is over-production, and its subsequent production costs are greatly reduced as overall quantity increases. Furthermore, problems may arise if the core competencies of the integration, due to their differences in operations, are very different.
